Transmission: GM 4T65E
Fluid Pan Gasket: FEL-PRO TOS18717 reusable type
After a few thousand miles, a drop of fluid will form on the tip of each individual bolt head. If I wipe the pan clean including all the bolt heads, the next day I can run my finger along the parting surface between the pan and the transmission and get a wet finger.
Questions:
- If these gaskets are reusable and never wear out, why are there new ones for sale?
- At which point do you replace yours?
- Do you replace yours with a reusable type, or do you prefer to go with a single use gasket doctored up with sealant?
Final comment:
Whenever I've used a rubber impregnated cork gasket coated on both sides with Permatex 2B, I've never had a leak. But I'm trying to stay with the OE type gasket because I'm trying stay OE as much as possible. We're supposed to trust the GM engineers.
