REMOVAL & INSTALLATION
See Figures 1, 2 and 3
- With the emergency brake fully engaged, place the vehicle in NEUTRAL with blocks behind the rear wheels to prevent any vehicle movement.
- Raise the vehicle and safely support it on jackstands.
- Place a suitable drain pan under the transmission pan to catch the fluid.
- Remove the retainer bolt securing the transmission fluid tube bracket to the transmission body.
- Loosen all the bolts securing the pan to the bottom of the transmission. Remove all the bolts except two at either end of the pan. As the bolts are removed, transmission fluid will begin to pour out.
- Once a majority of fluid has poured out of the pan, remove the remaining two bolts and lower the pan and attached filler tube out of the way.
- Clean all gasket mating material from the pan and transmission body.
- Using a new gasket between the pan and transmission body, raise the pan into position making sure the filler tube bracket is located properly along the transmission assembly.
- Install the pan retainer bolts and tighten each to 8-10 ft. lbs. (11-13 Nm).
- Connect the filler tube bracket using the retainer bolt. Tighten the bolt to 18-21 ft. lbs. (23-27 Nm).
- Lower the vehicle and fill the transmission with the correct amount of Dexron® type fluid. Start the vehicle and check the level. Add fluid if needed.
TRANSMISSION FILTER SERVICE
See Figure 4
Normal maintenance and lubrication requirements do not necessitate periodic automatic transmission fluid changes. If major service, such as a clutch band, bearing, etc. is required in the transmission, it will have to be removed for service. At this time, the converter, transmission cooler and cooler lines must be thoroughly flushed to remove any dirt which may be present.
When used under continuous or severe conditions, the transmission and torque converter should be drained and refilled with fluid as specified. Before adding fluid, make sure it meets or exceeds the manufacturer's specifications. The A4LD, 4R44E and 4R55E automatic transmissions use Dexron® II or III type transmission fluid. The use of incorrect type transmission fluid can result in transmission malfunction and/or failure. Refer to the Capacities Specification Chart for transmission refill recommendations with and without the torque converter.
To service/inspect the transmission filter, proceed as follows:
- Raise the vehicle and support it safely on jackstands.
- Place a suitable drain pan beneath the transmission.
- Loosen the pan attaching bolts slowly, allowing one side to tip down and drain the fluid. This removes all fluid from the pan, but not from the torque converter.
- When all fluid has drained from the transmission, remove and thoroughly clean the pan and screen.
- Remove the filter retaining bolts and lower the filter. Inspect the filter for metal particles which could signal potential transmission problems.
- Install a new filter using the retainer bolt to hold the filter in place.
- Discard the pan gasket and clean all gasket material from the mating surfaces. Install the pan and screen with a new gasket.
- Add 3 qts. of fluid to the transmission through the filler tube, then start the engine and shift the transmission through all gears, pausing briefly as each gear engages.
- Place the transmission in PARK and check the fluid level with the engine idling. Set the parking brake firmly.
