Transmission Pan Gasket Leak Help
I had the transmission on my 2002 Grand Cherokee rebuilt recently and now the transmission pan gasket is leaking. The rebuilt transmission is under warranty and I’m going to take it back in to have the leak fixed.

Question: What is the best type of gasket to use? Rubber, Cork, or something else? My local Jeep dealer is telling me to omit the gasket and just use a bead of ATF RTV sealant.

What do you folks think?

The Jeep is a stock 2002 Grand Cherokee Lerado 4x4 with the 4.7 V8 non H.O.

Re: Transmission Pan Gasket Leak Help
I always used RTV for the tranny pan, but after the rebuild they also put a gasket in between. It started leaking a bit and i fastened the bolts a bit, but next time i will use RTV again. It gives a little bit more work, especially during the cleaning, but if you apply it evenly, it will not leak.

Re: Transmission Pan Gasket Leak Help
have only used this for the past 6 years now,
Can be found at your local auto parts store normally. I use a rubber tranny pan gasket. These have less of a tendency to squish out when tightening the bolts. I put a bead on the pan, smear it evenly, set the gasket on the pan, put the bolts in the pan (the gasket holes are normally smaller so it holds the bolts in place) Set the pan up and thread the bolts in. I usually run 2 magnets in the pan due to Jeeps being notorious for failure. Any additional protection/prevention should be done on these.
