It seems to be leaking from a drain hole on the bottom of the bellhousing. There's a huge puddle.

2001 Jeep Grand Cherokee Transmission 42RE Fluid and Filter Part 2

It seems to stop, then comes right back. I've never changed a transmission before, so- can anyone give me any advise as to: 1 a good manual 2 tools needed 3 what type of transmission it is 42RE or 44RE? Also there were 2 transfer cases: one full-time and the other part time. First you disconnect the front and rear driveshafts from the transfer case. Then, while supporting the transmission with a suitable device, remove the transfer case You're looking at a bit of a project there; but if you're lucky - it might just be the seal for the torque converter.

Might not need a rebuild. Onthe other hand, it could be more serios, like a cracked case - in which case it would be beyond rebuilding. It needs to come apart to see what's going on.

Lead, follow, or get out of the way. If its shifting fine then just fix the leak. Generally an easy task. Most leaks will come from one of 3 places. It's a 44RE. I just ordered a Haynes. So, I talked to my uncle and the leak is actually from the transfer case in two spots. He looked at the transmission fluid and the color is good and it doesn't smell burnt. My next question is: do I have to go to a dealership for the seal and gasket?

Oh boy- how do I know which transfer case I have, full-time or part time?


Thanks for your help!! It has 3 main positions plus a neutral. I was curious if I could keep driving mine Do you want me to take pics and make a tutorial? Let me know! I have another truck that Im driving until I can get into it and see whats going on. Would love to know what you find out. Thanks Scott E-mail- kiblerscott hotmail. I still have a bad leak from the bell housing. Any ideas?Chrysler produced the 42RE and 42RH four-speed automatic transmissions.

42re transmission leak

The 42RH was a medium-duty transmission, while the 42RE was a heavy-duty version of the same transmission. They featured identical gear ratios, but the 42RE used electronic components to shift gears. The 42RH used a mechanical hydraulic system. Both transmissions matched engines in Dodge Dakotas and Jeep Cherokees, among other Chrysler vehicles.

Chrysler used the transmissions mostly in rear-wheel drive Dodge trucks, vans and its Jeep lineup with engines displacing from 3. The two transmissions were available starting in Both transmissions featured a Only fourth gear had the overdrive component.

The 42RE version had a new valve-body transfer system not compatible with any other Chrysler four-speed automatic. Its governor body and electronic components were also different from other electronically controlled automatic transmissions. The transmission was smaller than the 42RH because it did not need the mechanical governor components and tubes. The 42RH operated its bands, clutches and planetary gear sets via hydraulic mechanical components by applying pressure to the governor for shift speed control.

The transmission also featured a transmission temperature-control system that worked in tandem with the radiator temperature sensor to keep the transmission cool. The 42RE and 42RH had the same gear ratios: 2.

The two transmissions transmitted power from the engine to vehicles with a gross vehicle weight rating of 7, pounds or less. They also matched the to Dodge Dakotas equipped with the V-6, the to Jeep Grand Cherokee equipped with a 4-liter in-line six-cylinder engine and the to Jeep Grand Cherokee equipped with a 5.

Applications The two transmissions transmitted power from the engine to vehicles with a gross vehicle weight rating of 7, pounds or less.The control solenoid is an essential component of the transmission system.

It helps regulate the torque converter lockup, pressure control, and shifting and kickdown for passing gears. One common symptom of a faulty control solenoid is that your transmission may experience problems shifting gears. While in motion, your vehicle will slip out of gear.

Problems with the control solenoid are often accompanied by you seeing the check transmission light illuminated on your dashboard. Once you have verified that your transmission control solenoid has gone bad, you need to repair it immediately.

Consider replacing the component, rather than attempting to rebuild your entire transmission. Drive your vehicle to an automotive parts store. Ask a technician to connect a diagnostic computer code device to your vehicle. Most automotive stores will do this for free.

Use the diagnostic code to identify which transmission solenoid has gone bad. Your vehicle may utilize as many as six solenoids. Purchase a replacement solenoid from the automotive parts store.

Drive your vehicle to a safe place to complete your repairs. A well-ventilated garage may be a suitable option. Ensure the area you choose has an even ground and is fairly clear of obstacles.

Park your vehicle and turn off the ignition. Apply wheel blocks to the rear tires to help prevent the vehicle from rolling while you are replacing the solenoid. Raise the front-end of the vehicle using a car jack. Place the front axles on jack stands to keep the vehicle elevated.

Crawl underneath the hood area of the vehicle. Inspect the transmission carefully. Notice that there is a fluid compartment attached to the bottom of the transmission. Place an oil pan directly underneath this fluid compartment. Remove the bolts that secure the fluid compartment to the transmission using a wrench-and-socket set.

You may to try a few sockets before finding the right size socket for the transmission mounting bolts. As you are loosening the transmission bolts, transmission fluid will likely spill from the fluid container. This is normal and to be expected. Adjust the oil pan as necessary to catch the leaking transmission fluid.TorqueFlite also seen as Torqueflite is the trademarked name of Chrysler Corporation 's automatic transmissionsstarting with the three-speed unit introduced late in the model year as a successor to Chrysler's two-speed PowerFlite.

In the s, the TorqueFlite name was dropped in favor of alphanumeric designations, although the latest ZF-based transmissions with the eight-speed automatic has revived the name. Torqueflites use torque converters and Simpson gearsetstwo identical planetary gearsets sharing a common sun gear. Chrysler Corporation licensed this gearset from Simpson in The first Torqueflites provided three speeds forward plus reverse.

Gear ratios were 2. The transmission was controlled by a series of pushbuttons located on the vehicle's dashboard. The buttons were generally at the extreme driver's side end of the dash, i.

However, this was not always the case; the Dodge Phoenixa right-hand drive export model sold in Australia and South Africa, used the U. Button arrangement varied by vehicle model and year; sequence was reverse, neutral, drive, second, and first, from top to bottom with vertically arrayed buttons, from left to right with horizontally arrayed buttons, and clockwise starting at upper left with clustered buttons.

A parking lock was not provided until the advent of the aluminum-case Torqueflites in standard-duty A and heavy-duty Aat which point a lever was added adjacent to the pushbuttons: Moving the lever to the "park" position placed the car into neutral and engaged a lock pawl on the transmission's output shaft.

Moving the park lever out of "park" position unlocked the shift buttons so that a driving range could be selected. The buttons were replaced by conventional steering column- or floor-mounted shift levers in all automatic Chrysler-built vehicles for the model year, though floor levers were available in certain sporty models.

Like a vehicle with a General Motors Hydramatica vehicle with a Torqueflite transmission starts out in first gear when the drive or second position is selected. This is in contrast to vehicles with several automatics from Ford and Borg-Warnerwhich start out in second rather than first if the second position is selected. With came the addition of a canister-style fluid filter installed in the cooler line. Forthe canister filter was eliminated, and the transmission's internal intake screen was replaced by an efficient Dacron filter.

Forthe twin-cable shift and park control mechanism a holdover from the push-button operation was replaced by a solid shift control linkage consisting of a series of pushrods, rotating rods and levers.

The rear pump was eliminated, which simplified and cost-reduced the transmission but rendered push-starting impossible; Chrysler engineers reasoned that improved electrical and fuel systems reduced the need to push-start vehicles, and safety concerns weighed against doing so. With the elimination of the rear pump the oil filter was designed with a single oil port. Inpart-throttle downshift functionality was added to A transmissions used with six-cylinder engines.

This feature permitted the transmission to shift from third to second gear in response to moderate accelerator pressure. Previously, an automatic downshift occurred only if the driver pushed the accelerator to the floor. This change was made to maintain acceptable in-town performance with taller final-drive ratios in the rear axle — 2.

Part-throttle downshift functionality was extended to V8 As inand to most A transmissions in to Inmost Torqueflite transmissions gained a lockup torque converter clutch to mechanically connect the converter's impeller and turbine, eliminating slip for better highway fuel economy.

This addition required the removal of the torque converter drain plug. Fora wide-ratio gearset was released for the A, A and A, with 2. Torqueflite was an available option or standard equipment, depending on model and year, on all Chrysler products: PlymouthDodgeDeSotoChrysler and Imperial. It was also used by American Motors beginning inwhere it was named Torque-Commandas well as by JeepInternational HarvesterMaserati QuattroporteMonteverdi [1] and Bristol [2]as well as several brands of light and medium-duty trucks and panel vans.

When installed in Dodge trucks and vans, the transmission was marketed as LoadFlite. In the s, the transmissions were renamed, however the original Torqueflite design remained the basis of many Chrysler designed and built transmissions through and FWD transaxles through Torqueflite transmissions and transaxles made through were assigned arbitrary engineering designations consisting of the letter "A" followed by three digits.There is a common issue with shifting on a number of Jeep Grand Cherokee models as they age and their mileage increases.

You're often still able to drive the vehicle, but it only operates in one or two gears. For example, you may find that you're only able to drive the car in the automatic transmission's third gear, only being able to select the other two gears when you shift the transmission manually.

The most common cause of transmission problems is the easiest to fix: check the fluid level in the transmission and restore it to the proper levels. Very often, this will solve the problem. But Jeep Grand Cherokees seem especially prone to more serious transmission problems, and some owners are quite vexed at their inability to determine the causes. On models with OBD onboard diagnostics systems, a code scanner plugged into the diagnostic port gives you a reading to help identify the problem.

However, easy solutions still exist even if you don't have a code reader. Below, you'll find the list of Transmission Fault Codes for Jeep automatic transmissions.

You may or may not be skilled enough to actually fix the problems indicated by the flash codes yourself, but you're better-armed with an understanding of where the issues lay as you seek help from a mechanic. Matthew Wright.

Updated September 16, Immediately begin counting the number of flashes displayed by the Overdrive Off Switch indicator lamp. There will be two sets of flashes, separated by a pause. The number of flashes in each group indicates the first and second digit in the flash codes. A code 55 identifies the end of flash code transmission.The leak can easily be mis-diagnosed as a leaky pan gasket.

A lot of unsuspecting consumers may end up spending a thousand dollars or more to rebuild a transmission with a leak like this. The vehicle that the transmission leak occurred in, in this case was a Jeep Grand Cherokee Laredo 3. The transmission fluid leak appears to be coming from the pan seal or gasket at the right front corner.

However the common leak is from around the electrical connector housing for the wiring that goes into the transmission. The fluid leak can progress to a fairly rapid leak. This trans. The plug is undone by twisting the plastic tab downward while slightly pulling outward.

Start with a cold engine, since the service area is near the exhaust. Place a drip pan under the transmission to catch fluid. Disconnect the wiring harness connector by turning to the left or downward. Be sure to clean area where the o-rings will contact and that the old o-rings are removed. The 7mm screw should be tightened with hand tools only and caution taken not to forcibly start it. After it is started it should NOT be over-tightened. Clean the fluid off from the work area with a part cleaner such as brake clean.

Dry area with compressed air. Check transmission fluid level with vehicle running and top off if necessary.
