REMOVAL
Transmission
CAUTION: Whenever a transmission has been disassembled to install new parts the
transmission fluid cooler tubes must be cleaned and backflushed. Use a suitable torque
converter/fluid cooler cleaner. If equipped a new oil- to-air cooler must also be installed.
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 use.
CAUTION: After transmission is removed for a major overhaul, it is important to
completely clean all transmission components, including torque converter, oil- to-air cooler if
equipped, cooler inlet tube, main control valve body, clutches and all coasting booster valve
shuttle balls after any transmission repair 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 use.
The cleaning of foreign material from the direct clutch check ball is often omitted. This
omission can lead to repeat repair of the transmission.
If equipped a new oil- to-air cooler must be installed under the following conditions; for
installation refer to Section 307 - 02 .
z 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. Place the transmission range selector lever in NEUTRAL.
2. Disconnect the battery ground cable. For additional information, refer to Section 414 - 01 .
3. Raise and support the vehicle. For additional information, refer to Section 100 - 02 .
4. Remove the dual converter Y pipe. For additional information, refer to Section 309 - 00 .
5. Disconnect the transmission harness electrical connector.
