Need to do a trans pan reseal, any tips?

The pan on my 98 V8 is leaking. I want to get that fixed that so I can park in my driveway haha. I thought I've read about people upgrading or switching to a different pan? It looks like I have the stock pan and some type of RTV was used to seal it but it didn't do a very good job. I thought I recalled coming across a thread saying there was a factory jeep gasket that worked well but maybe I'm mixed up. I would like to get this leak corrected even if it means spending a few extra bucks to do it right. Whats the best way to get this fixed?

Ive read some about getting a different, better pan. These ones are thin and I think tend to warp- especially when you drag em over a bunch of rocks and ****. I think a common problem is people over tightening the pan bolts. Itll smoosh out the gasket and loose the seal. Get a torque wrench

Get a new pan. Get the factory re-usable pan gasket. It's plastic with a rubber o-ring type sealing surface. Don't use any RTV or other stuff on it.

I've had the same one for years and it's been on and off many times for other trans jobs and it still doesn't leak a drop. You could put a straight edge across your existing pan once it's off and see if it's deformed at the pan rails or not.

I ordered a new one anyways, mine has some dings in it. 20 bucks from Jeep for a new one. Hell the gasket almost costs more than the pan haha.

Yep, pan and the mopar gasket, torque is only like 13ft lbs on the bolts so don't over tighten.

Do yourself a favor and get a small torque wrench. Mine will go down to 14 but in the manual it says its only good down to 20 and they were right.

use a jack to hold the pan up so you can align the gasket better

After all these pan gasket replacements, I never once thought about that.... Good tip.

High tac is a good option as well. It'll keep the gasket in place while fitting the pan. Used it many times for different gaskets and has never let me down.

If you use an ATP gasket, there are four tabs on the gasket. The hole near each tab is smaller and will hold a bolt and that keeps everything aligned for installation.
