DeVille DTS V8-4.6L VIN 9 (2002)
Fluid Filter - A/T: Service and Repair
Scavenge Screens and Seals Replacement
Removal Procedure
1. Raise the vehicle and support. Refer to Vehicle Lifting.
2. Place a drain pan under the transmission bottom pan in order to catch the fluid.
Important: Removing the bottom pan on the Hydra-Matic 4T80-E only partially drains the transaxle fluid. The side cover and the torque converter
hold the remaining fluid. To drain fluid from the side cover, remove the drain plug in the case after bottom pan removal. There is no need to drain the
torque converter during most service procedures.
3. Loosen the bottom pan bolts. Drain any fluid in the pan.
4. Remove the bottom pan bolts, pan, and seal.
5. Inspect the bottom pan for dents or nicks on the sealing surface. If damaged, replace.
Important: The bottom pan seal is reusable. Replace with a new seal only if sealing surface is damaged.
6. For proper sealing, clean and dry the bottom pan and the case sealing surfaces. In order to maintain proper bolt torque, the bolts and tapped holes
in the case must be clean and dry.
7. Remove the left and/or right scavenger screens.
8. Remove the seals. Use a small screwdriver to pry the seals from the case. Do not score or damage the case.
