Picture Of Manual Transmission Fill Bolt On 86 Toyota
Nov 09, 2013 I have a 89 Toyota extenda cab 4×4 I just put a new tranny and clutch in it as well as new master and slave cylinders and the rubber hose between the metal lines the system keeps loosing pressure iv tried every thing from warrantying the master to even using a air powered vacuum bleeder iam at a loss and getting very frustrated this has to be something very simple im over looking any help. Sep 11, 2006 Discuss How to change transmission fluid? Corolla, 1999 Auto in the alt.autos.toyota forum at Car Dealer Forums; I'm trying to change my own transmission fluid but it my manual. Mar 14, 2016 Transmission fluid drain bolt is often too tight. This easy trick will open it easypeezy. Works for all vehicles. Remember: righty-tighty, lefty-loosey. Disclaimer: use all methods at your own risk. Dec 07, 2009 The drain and fill procedure on the Toyota 5 speed AT (mated to the 4.0L V6) is different than that of traditional transmissions. Since this transmission has no dipstick to check fluid level, the correct level must be confirmed by an overflow plug on the bottom of the pan. Jan 13, 2017 I'm wondering because the diagram I saw on alldata showed a speed sensor going into that hole, but your picture looks like it's just a dumb plug. If that's the case, I wonder if on some models of Toyota vehicles there is some purpose for that hole in the transmission (like for another speed sensor or something). I don't know, just thinking as I.

Toyota Corolla TransmissionFluid Change Guide
How to drain and refill the 'ATF'(automatic transmission fluid) in a 9th generation 2003 to 2008 Toyota Corollasedan.
Oct 07, 2007 Car is a 05 Toyota Corolla with a 5 speed manual transmission. 2 quarts of your favorite Manual transmission oil (I've used Mobil 1 gear oil and now Amsoil manual transmission oil and there is NO question what to use between those 2. Its night and day. ) Here is a top view of the engine/transaxle. Close up of Fill plug; And where the drain plug is. Feb 06, 2016 Several options: 1) Remove shifter and pour the oil in from the top until it dribbles out the fill plug. 2) Connect a piece of hose to the bottle and try to find a high spot to hold the bottle, then squeeze the bottle until you get enough in. Reguires several refills and the damn hose will definitely slip off at least once and spill gear oil down your sleeve and/or into your eyes.

2005 Toyota Corolla 1.8L I4 | 1ZZ-FE @ 115,000 Miles | Pull Up Transmission Dipstick |
| Thisautomotive maintenance tutorial was specifically written to assistowners of the ninth generation (2003, 2004, 2005, 2006, 2007 & 2008)Toyota Corolla with the 1.8L I4 engine in performing a simple drainand refill of the automatic transmission fluid or 'ATF'. Owners of other Toyota or relatedPontiac vehicles with similar automatic transmissions such as theMatrix, Vibe, Voltz, RAV4, Celica, Camry, Yaris, Tacoma and Avalonmay also find these DIY instructions to be helpful. Toyota claims that the ATF fluidshould last the 'lifetime' of the vehicle under normal drivingconditions. So by doing a quick drain and refill of about 50% of theATF fluid at least every few years or every 15,000 to 30,000 miles,your car's preventative maintenance will be far ahead of the average Corolla. The items needed to complete thisprocedure include a 14mm socket with a 3/8' drive ratcheting wrench,a used oil catch container, a gallon jug marked in quarts, anautomotive funnel a new crush washer & 4 U.S. quarts ofgenuine ToyotaATF Type T-IV. Optional items include a floor jackand two jack stands or automotive ramps to raise the vehicle foreasier access to the drain plug. | ||
Raise Front of Vehicle | Support With Jack Stands | Gallon Bottle & 4 Quarts ATF |
| This procedureshould be done when the engine is warm to help suspend any contaminantswithin the old transmission fluid and to allow the old fluid to drain outmore quickly. If the engine is very hot, allow it to cool a bit to prevent from burningyourself on the underside of the engine bay or when you drain the ATF fluid. The first two steps are to open the hood andthen pull up the red plastic handled transmission dipstick an inch or two. The dipstick is located at the front right(driver side) of the engine bay next to the 12V automotive battery and belowthe air intake hose. Lifting out the transmission dipstick willhelp prevent a vacuum from forming and allow the old fluid to drain out morequickly. You may be able to reach the transmissionfluid drain bolt with out raising the vehicle. I found it easier to lift the front of thecar with a floor jack at the jack point under the center of the engine bay. Then securely support the vehicle with the twojack stands. | ||
Jug Marked Half Quart Lines | Transmission Oil Pan | 14mm Drain Bolt |
| Gather together theused oil catch container, a 14mm socket and a 3/8' drive ratcheting wrench. I'd recommend wearing Nitrile rubber gloves tokeep your hands clean during the next steps. Used automotive oil may becarcinogenic (cancer causing). Slide under the front driver side of theengine bay and locate the black metal transmission oil pan. The transmissionoil drain bolt is located near the rear edge of the pan with the bolt headfacing down towards the ground. | ||
Slide Basin Under Drain Bolt | Loosen Counterclockwise | Spin Out Drain Bolt |
| Position the usedoil catch basin to just below the drain bolt. Loosen the transmission fluid drain bolt in thecounterclockwise direction with the 14mm socket and ratcheting wrench. | ||
Inspect & Replace Washer | Draining Out Old ATF Fluid | Dark Fluid After 115,000 Miles |
| Spin out the drainbolt, clean it and inspect the metal crush washer. The best practice would be to replace thecrush washer, but you may be able to re-use the washer if it appears to bein good condition. If the washer appears to be falling apart,use a new one. The part number is Genuine Toyota Gaskets 90430-12031. (These are also the same washersfor the 14mm oil drain plug.) Allow the old transmission fluid to drain outfor at least a few minutes or until the flow slows to an occasional drip. This is the first time I have 'changed' thetransmission fluid on our 2005 Corolla with 115,000 miles on the odometer,so I wasn't surprised that it was a very dark brown or black color with aslightly pungent burnt odor. Fresh ATF fluid is a translucent bright redcolor and just smells like most other new petroleum based automotive fluids. I bought the new Toyota T-IV ATF fluidat my local Toyota dealership parts counter but I plan on buying it onlinein the future. | ||
Spin In 14mm Drain Bolt | Tighten Clockwise 13 ft-lbs | Funnel In Measuring Jug |
| Clean off the areaaround the drain hole with some paper towels or a clean rag. Make sure that the old crush washer is notstill attached to the transmission pan. If necessary, attach a new crush washer tothe drain bolt. Spin in the drain bolt by hand a few turns inthe clockwise direction to prevent it from becoming cross threaded. Tighten the drain bolt in the clockwisedirection with the 14mm socket and ratcheting wrench to just past hand tightor about 13 ft-lbs (156 in-lbs) of torque if you have a torque wrench. Double check that the ATF drain bolt is tightbefore moving on to the next steps. | ||
Pour In Old ATF Fluid | About 3.65 U.S. Quarts | Insert Funnel In Dipstick Hole |
| Insert anautomotive funnel in to the gallon jug that you marked with a line everyhalf quart. (To create a measuring jug, just pour in twocups of water from a kitchen measuring cup and mark the level with apermanent marker. Every 2 cups is a half quart and every 4 cups is a quart.) I was able to drain out about 3.65 U.S.quarts of old ATF fluid. That is consistent with what I've read on Toyotaforums of other Corolla owners draining out about 3.5 quarts for a drain andrefill procedure. (If you would like to clean the metalshavings from the transmission pan magnet and replace the filter, here are afew filter kits with their part numbers: Wix 58040, Beck Arnley 044-0330, Purolator P1296,GKI TF1242 and Toyota 35330-12040. If you raised the vehicle, lower it from thejack stands using the floor jack. | ||
Lower Vehicle From Stands | Pour In New T-IV ATF | Poured In 3 U.S. Quarts |
| Insert a smallautomotive funnel in to the transmission dipstick hole. The owner's manual for the 2005 Toyota Corolla Sstates that the automatic transaxle's fluid capacity for a drain and refillis 3.2 U.S. quarts (3.0 Liters or 2.6 Imperial Quarts). Slowly pour in only about 3 to 3.2 U.S.quarts of the new Toyota ATF T-IV in to the transmission fluid dipstickhole. It is far better to have slightly less fluidthat necessary in the transmission than to overfill it. | ||
Run Engine - Check Dipstick | ~3.6 U.S. Quarts Added | Check & Replace Dipstick |
| Temporarily replacethe transmission dipstick while you perform the following steps to check thetransmission fluid level. 1. Turn onthe engine. The ATF fluid level should be somewherebetween the two notches that indicate the 'HOT' range on the dipstick. If the fluid level is far below the 'HOT'range, turn off the engine and slowly pour in more ATF fluid and repeat theprocess until the level on the dipstick reaches the correct range. To keep things simple, I just poured in about3.6 U.S. quarts of new ATF to replace the amount that I had drained andmeasured with the gallon jug. Luckily, the level on the dipstick was almostin the middle of the 'HOT' range. I'd recommend checking the ATF fluid levelagain after your next trip. Be sure to record the ATF fluid change inyour vehicle's service records.

Vehicles made by American Motors Corporation (AMC) and Jeep incorporated a variety of transmissions and transfer case systems. This article covers transmissions used in the following vehicle models and years:
- All American Motors (AMC) passenger cars, 1954-1988
- Jeep Cherokee XJ (1984–2001)
- Jeep Comanche (1985-1992)
- Jeep CJ (1976–1986)
- Jeep Grand Cherokee WJ (1999–2004)
- Jeep Grand Cherokee ZJ (1993–1998)
- Jeep Wagoneer/Grand Wagoneer (1963–1991)

- 2Transfer cases
- 2.1Dana
Transmissions[edit]
Transmissions used in later AMC vehicles came with either a 21-spline or a 23-spline output shaft. Transmissions coupled to four-cylinder engines typically used 21-spline output shafts. The 23-spline manual transmission was universal in the Eagle lines and was generally used with six-cylinder applications. All transfer cases were available with inputs matching either 21- or 23-spline shafts, making transmission swaps possible among various models and years. However, the depth of transfercase input and length of trans output (measured from the mounting flange) changed, and there is 15/16' difference between early and late models.

Aisin-Warner[edit]
The Aisin-Warner four-speed automatic transmission (AW4) was co-designed by AMC and Borg Warner then built by Aisin in their then new facility for use in then all new Cherokee XJ's new inline six-cylinder 4.0 L design. It was manufactured by Aisin-Warner, a member of the Toyota group, in partnership with Borg-Warner. It shares many parts with the Aisin 450-43LE that is used in Toyota off-road vehicles.
The AW4 is also used behind the 2.5 L (150 CID) AMC Straight-4 engine. It has a removable bell housing with a mount for the crankshaft position sensor. Early AW4s used 21-spline output shafts. In 1991 the AW4 was changed to a 23-spline output shaft, concurrent with adoption of the High Output (commonly known as H.O.) inline six-cylinder engine. Some sources state that the output shaft spline change occurred for the 1990 model year. The change most likely occurred during the 1990 model run with early 1990 models receiving 21-spline transmission and later models receiving 23-spline. If swapping transmissions in 1990 model year vehicles either swap the transfer case as well or make sure to check spline count. The input on the transfer case can also be changed to match the output shaft spline count. Rear-wheel-drive-only transmissions all have the same spline count on the output shaft, only 4x4 models are affected by differing spline count.

Gear Ratios for the AW4:
- 1st: 2.80
- 2nd: 1.53
- 3rd: 1.00
- 4th: 0.75 (23-spline, 0.705 21-spline)
Models that used the AW4:
- 1987–2001 Jeep Cherokee (XJ) 4.0 L
- 1993–1993.5 Jeep Grand Cherokee (ZJ) 4.0 L
- 1987–1992 Jeep Comanche 2.5 L
- 1987–1992 Jeep Comanche 4.0 L
Chrysler/TorqueCommand[edit]
For the 1972 model year, AMC began to purchase a variation of the Chrysler-developedTorqueFlite transmission and named it TorqueCommand. All TorqueCommand automatics used 23-spline output shafts. Later on, as AMC revised their mainstay engines to have lighter casting technology, these transmissions were available in both the Chevrolet small V6 engine pattern (used on the AMC 150 I4) and the AMC late model pattern that was used on their I6 and V8 engines. Other than the bell housing pattern (main transmission case) and the torque converter, the AMC version is the same as other Chrysler transmissions—all parts interchange (torque converters do not interchange - unlike the Chrysler torque converters which have a pressed on ring gear for the starter teeth AMC uses a traditional 164 tooth flexplate similar in design to those used by Ford.
AMC used several different 9XX transmission cases for different engines. 1980 up CJs and 1980 to early 1983 AMC Eagles with 4-cyl used a small block Chev pattern. The 1983 up used 60 degree V6 pattern for the 2.5 and 2.8 (outsourced from GM through 1986) engines. The 2.5 L kept the same pattern through the end of production (also shared with FWD Cadillac engines). For 1979 through 1981, there was also an Audi 2.0 L pattern 904.
Transfer cases[edit]
The transfer case is an auxiliary transmission that connects the front and rear axles. It also commonly provides a selectable secondary gearreduction. AMC and Jeep vehicles have used several different transfer cases in their various models.
| Case | Offset | Spline | Ratio | Bolt Pattern | Years Used |
|---|---|---|---|---|---|
| Borg-Warner 13-39 | Both Right | 10 | 2.57:1 | THM400 | 1973–1979 |
| Dana 18 | Both Right | 6 (10) | 1.98:1, 2.42:1, 2.46:1 | Texas | 1940–1971 |
| Dana 20 | Front Right | 6 (10) | 2.03:1 | Texas | 1963–1979 |
| Dana 300 | Front Right | 23 | 2.62:1 | Round (New Process) | 1980–1986 |
Dana[edit]
Jeep has used three different transfer cases made by the Spicer Division of Dana Holding Corporation. They are the 18, 20, and 300 models.
Dana 18[edit]
The Dana 18 is a gear driven part-time transfer case.[2] Both the front and rear output shafts are offset towards the passenger side of the vehicle. Drive modes offered include 2-wheel high, part-time 4-wheel high, and part-time 4-wheel Low. All Dana 18 cases are cast iron and use the 'Texas' bolt pattern with five bolts holding on the transfer case. There are five variations:
- 27-tooth drive gear, 3/4' intermediate shaft and 1.98:1 low range, 3' input hole
- 26-tooth input gear, 3/4' intermediate shaft and 2.42:1 low range, 3' input hole
- 26-tooth input gear, 1⅛' intermediate shaft and 2.42:1 low range, 3' input hole
- 26-tooth input gear, 1¼' intermediate shaft and 2.42:1 low range, 3' input hole
- 29-tooth input gear, 1¼' intermediate shaft and 2.46:1 low range, 4' input hole, Dana 20 case
The normal (3') input Dana 18s are interchangeable, but the input gear must match the transfer case. The 'big hole' (4' input) Dana 18 is transmission-interchangeable with the Dana 20. Almost all Dana 18 and Dana 20 input gears are 6-spline; the only exception is the one used with the 10-spline version of the T14 transmission. Some International Scout Dana 20s with a 727 automatic transmission use a 23 spline 26 tooth gear
All Dana 18s have front and rear outputs offset to the right side. Most vehicles built with a Dana 18 have the rear axle offset to the right side to accommodate this. Most other transfer cases used in Jeeps have a centered rear output that lines up with the input shaft. The Dana 18 always has gears turning, which makes it noisier then some other transfer cases when in two-wheel-drive mode.
Applications:
- 1941-1945 Willys MB
- 1950-1952 Willys M38
- 1941-1971 Willys Jeep Truck
Dana 20[edit]
The Dana 20 can be identified by the center rear output, cast iron construction, and deep oil pan. Like the Dana 18, it uses the Texas bolt pattern to hold the transfer case in place. This is a heavy-duty, gear-driven part-time[2] transfer case with a 26-tooth input gear. The output for the front drive shaft is on the right side and the rear output is in line with the input. This enables 2-wheel High to be direct-drive, which is quieter. Otherwise the Dana 20 offers the same drive modes as the Dana 18. Its low range has a ratio of 2.03:1.
The Dana 20 is generally compatible with the 'big hole' Dana 18. One exception is the version used with the THM400 in full-size Jeep trucks, which used a different spline number on the input gear.
Applications:
- 1963-1979 Willys-Overland Jeepster
- 1979 International Scout with 727TF AT uses the 23 spline 26 tooth gear.
Dana 21[edit]
The Dana 21 part-time gear system with single-speed case with automatic transmission.[3] The Dana 21 is essentially a Dana 20 without a low range (offering only 2-wheel high and part-time 4-wheel high).
Applications:

- 1963-1969 Jeep SJ
- 1963-1969 Jeep Gladiator
Dana 300[edit]
The Dana 300 part-time gear-driven transfer case.[2] That uses a round bolt pattern and has a nearly flat oil pan. It is a heavy-duty, gear-driven transfer case with a 23-spline input shaft. The case is cast iron but the tail housing is aluminum. The ID number C300-15 is stamped on the case. The output for the front drive shaft is on the right side and the rear output in line with the input. Low range is 2.62:1.
One common modification of the Dana 300 is to add oil paddles to the main shaft to prevent oil starvation of the rear bearing.
The Dana 300 was used in Jeep CJs from 1980 to 1986. The 1980 factory original came with a shorter tail housing and a longer rear drive shaft. The Dana 300 should fit behind all TorqueCommand 4x4 transmissions.
Applications:
- 1980-1986 Jeep CJ
New Process/New Venture[edit]
In general, New Process transfer cases are identified by a three-digit code. The first digit (1 or 2) determines the number of gearranges. The second digit is a series number that reflects design, and provides minimal information about torque handling. For example, if the second digit is a 1, there is no two-wheel-drive option; if it is a 2, 2WD is available. Other numbers have similar meanings. The third digit indicates differential type: 1 means locked (no differential), 2 means open, 3 means electric locked, 4 and 5 both indicate an asymmetricaltorque split planetary gear and gear drive, 6 means an electronic clutch pack, 7 means a hydraulic clutch pack (except for the unique 207), and 9 means a viscous coupler.
The AMC Eagle used three New Process transfer cases (Models 119, 128, and 129) that were single speed versions of the models (219, 228, and 229) that were used in 1980 and newer Jeeps. There was no difference between the Eagle versions and the Jeep versions other than the addition of a low range, indicated by the 2 as the first digit.
New Process transfer cases are chain-driven and use a circular 6 bolt, 23-spline input on the case. The output for the front drive shaft is on the left side. The New Process transfer cases used by AMC attach the same as the Dana 300 except that New Process cases have the front output on the left side. Interchange ('flip') is possible, but there is an indexing lug in the pattern, in an attempt to allow the transfer case to attach in only one position. Thus, some modification on the transfer case or the adapter is required.
Because of changes in the name of the manufacturing company, new versions of the NP231 and NP242 are referred to as NV (New Venture) or NVG (New Venture Gear).

↑ The 249 was available in two versions. The early (1993–1996) version had no differential lock and the viscous coupling spanned the center differential, creating a 50/50 torque split. The later version (1996 and beyond) had a viscous front drive, creating a rear torque bias, but included a provision to lock the center differential.
Overdrives and underdrives[edit]
Borg-Warner overdrive was available from early 1960 to 1969. The Borg-Warner overdrive case is 11¾ inches long (less torque tube adapter, if required), including the 11⁄2-inch-thick (38 mm) adapter. A complete T96 with overdrive is 18¾ inches long from front of case to end of tailshaft housing. The overdrive unit is the same for all.
The Dana 18 has a power take-off (PTO) attachment on the case that can be used to drive equipment that accepts PTO input. A unique feature of the Dana 18 is the overdrive that attaches in the PTO port in the back of the system. An adapter allows use of both the overdrive and the PTO attachment, but it is no longer produced.
Laycock de Normanville overdrive was available from 1974 through 1976 for inline six engines with the 150T and for V8 torque tube cars with the T89.
Transmission to transfer case adapters and clocking[edit]
Transmissions end with a splined tail shaft, more commonly called an output shaft. When one or more auxiliary units are bolted to the main transmission, these are called adapters, extension housings, or tail housings. All factory applications with a four-wheel drive transfer case require an adapter, and many upgrade transmissions that would otherwise be incompatible can be adapted to Jeep transfer cases.
Clocking refers to the angle at which the transfer case is tilted with reference to the horizontal plane. Stock Jeep clocking for the Dana 300 (1980–1986) is usually 23° and stock Eagle and Jeep/New Process clocking is usually 13°. Many factors, most notably ground clearance and front drive shaft clearance, can necessitate a change in the clocking angle. Some aftermarket adapters feature flanges with multiple clocking options.
Bell housings[edit]
The bell housing bolt pattern for the old AMC 196 Straight-6 engine is the same as for the more modern early 199 and 232 (used from 1964 to 1971), but the 196 had different dowel pin sizes. AMC's 1956 to 1966 V8s used a different bell housing bolt pattern that was slightly larger in diameter than the six cylinder bell. When AMC discontinued their first V8 engine design after 1966, the bell housing changed; all 1966-up V8 bell housing bolt patterns are the same. The bell housing for six-cylinder engines changed to match the V8 in 1972 when AMC switched from Borg-Warner to Chrysler transmissions automatic. The flywheel also changed from 153 teeth (a common Chevy size) to 164 teeth (a common Ford size). Starter motors used with the 1966-up V8 bellhousing were sourced from Motorcraft which interchanges with the Ford V8 and some of their inline sixes (which uses a separate starter solenoid) - the Jeep 4.0 L uses a Mitsubishi-designed starter which has an integrated solenoid which is lighter in weight but retaining the two mounting bolts with a threaded top hole and unthreaded hole which bolts to the transmission bellhousing.
The Iron Duke I4 used by AMC in Jeeps from 1980 to 1983 used the standard small block Chevrolet bolt pattern bell housing. The later (1984-02) AMC I4 had the GM 60 degree V6/I4 bolt pattern, and this was retained for the life of the engine. AMC often used lighter duty transmissions with the four cylinder engines.
