Aurora V6-214 3.5L VIN H SFI (2001)
Fluid Pan: Service and Repair
4T80-E
Oil Pan 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 not reusable. Replace with a new seal after removing the bottom pan for any service.
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.
Installation Procedure
1. Install the bottom pan, new seal, and bolts. Finger-tighten the bolts.
Notice: Refer to Fastener Notice in Service Precautions.
