How to Service and Repair the Automatic Transmission Filter on the 4T80-E Transaxle on Buick Lucerne?

A:
The fluid filter servicing procedure for 4t80-e automatic transaxle requires vehicle elevation with support alongside setup of a drain pan beneath the transmission bottom pan. Draining transaxle fluid requires the removal of the bottom pan but leaves some fluid trapped by the side cover and Torque Converter since removing the Drain Plug from this cover after bottom pan removal serves most service operations.

Aluminum bottom pans should be examined for damage to the sealing surface since a replacement is needed only if there is evidence of damage but the seal is reusable unless damage exists. Proper sealing depends on dry and clean conditions of both bottom pan and case sealing surfaces and clean and dry bolts and tapped holes need to be ready for torque. Use a small screwdriver to uninstall left and right scavenger screens and their seals while being cautious to protect the vehicle case.
