How to Service and Repair the Automatic Transmission Filter on the 4T80-E Transaxle on 2006 Buick Lucerne?

Question

Accepted Answer

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. Begin by loosening the bottom pan bolts during fluid drainage and afterward remove all bolts and pan with its seal. 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. Install the new left and right scavenger seals and screens before installing the bottom pan along with the seal and bolts which should be lightly tightened. The pan bolt torque procedure starts with 3 nm (27 inch lbs.) followed by 6 nm (53 inch lbs.) and concluding with 12 nm (106 inch lbs.). Put the vehicle into its lowest position and fill it with transmission fluid of dexron-iii type up to the required level.
