VEHICLE REPAIR
Fluid Pan, Gasket and Filter
1. Normal maintenance requires periodic automatic transmission fluid changes. If a major repair, such as a clutch, band, bearing, etc., is required, the automatic transmission will also have to be
removed for repair. At this time, the torque converter, transmission cooler and tubes must be
thoroughly flushed to remove any dirt. The transmission fluid needs to be changed if evidence
of fluid contamination is found. When used under continuous or severe conditions, the
transmission and torque converter should be drained and refilled with fluid as specified.
2. CAUTION: Do not use any supplemental transmission fluid additives or cleaning
agents. The use of these products could cause internal transmission components to fail;
this will effect the operation of the transmission.
CAUTION: Use of a fluid other than specified could result in transmission failure.
Refer to the vehicle certification label affixed to the LH front door lock face panel or door pillar
for the transmission code.
3. When filling a dry transmission and torque converter, refer to General Specifications chart in this section for capacity. Check the fluid level.
Removal
1. Disconnect the battery ground cable. For additional information, refer to Section 414 - 01 .
2. Raise and support the vehicle. For additional information, refer to Section 100 - 02 .
3. Place a drain pan under the transmission fluid pan.
4. Drain transmission fluid. zLoosen the transmission fluid pan bolts and allow fluid to drain. After fluid is drained
remove the bolts.
