Removal
Special Tools:
CAUTION: Whenever a transmission has been disassembled to replace worn or damaged parts the transmission fluid cooler tubes must be cleaned and backflushed. Use the torque converter/oil cooler cleaner. The oil-to-air (OTA) cooler must also be replaced. When internal wear or damage has occurred in the transmission, metal particles, clutch plate material or band material may have been carried into the torque converter and fluid cooler. These contaminants are a major cause of recurring transmission troubles and must be removed from the system before the transmission is put back into service.
NOTE: After transmission is removed for a major overhaul, it is important to completely clean all transmission components, including torque converter, oil-to-air cooler, cooler inlet tube, main control valve body, clutches and all coasting booster valve shuttle balls after any transmission service that generates contamination. These contaminants are a major cause for recurring transmission concerns and must be removed from the system before the transmission is returned to service.
The cleaning of debris from the direct clutch check ball is often omitted. This omission can lead to a repeat servicing of the transmission.
The oil-to-air cooler must be replaced under the following conditions. ^ Evidence of transmission assembly or fluid contamination is found due to the following transmission or converter failure modes:
^ major metallic failure
^ multiple clutches or clutch plate failures
^ sufficient component wear which results in metallic contamination.
1. Install a memory saver.
2. Disconnect the battery ground cable.
3. Raise the vehicle on a hoist.
4. Remove the radiator air deflector.
5. Position a drain pan under the vehicle.
6. Drain transmission fluid.
Loosen the transmission fluid pan bolts and allow fluid to drain. After fluid is drained remove the bolts and the pan.
