    Degreased the 02 to look for a leak and found that the trans pan gasket is the culprit. Looks like it took a little hit on the drivers side. Tried to snug her up a little bit which, of course, made it worse. So my question: Have you had better luck with a gasket or RTV?????

    I know I gotta make sure the pan lays flat where the flange was dented.

    Gasket. Always. Sounds like a different pan is needed as well.

    Get a new pan. Got a molar pan on eBay for 50 or less I think. Get a rubber gasket from the auto parts store. And get the transmission fluid specific RTV. There is special RTV just for use with at trans fluid. Use it. It works great. Permatex makes it

    That is what got my 2002 needed to finally seal

    Are you saying that you use a rubber gasket and RTV? I'm gonna check the pan to see if it's warped and go from there. There's just a tiny little dent in the flange that's actually hard to see.

    Use either/or. Both is a sure sign of amateur cobbling.

    Like stated go down to the dealership and buy a new pan(cheap) and while you are there pick up a tube of Chryslers RTV for the trans pans(good stuff).


    All Chrysler trans are not machined for gaskets and more then anything they will leak with a gasket and never use RTV and a gasket together.Basically use the correct RTV and all will be well and a much better seal then a gasket.

    Yea I think I used both. I thought my pan was ok to...but when it still leaked twice....I replaced it. It can look ok, but way easier to just get a new pan. I think I did use both...not sure though. But definitely the transmission RTV for sure.

    When dealing with certain parts like diff covers, trans pans, oil pans etc...this is what I go by:

    Stamped sheet metal=Gasket

    Cast aluminum w/machined mating surface=Permatex The Right Stuff sealant (no gasket)

    Got the pan off and all cleaned up. It looks good and did not take a hit but does have a very slight warp to it when I put it on a glass table top. I picked up a Fel-pro gasket at Autozone but I can't tell if it's paper or rubber. The plan is to install it tomorrow and see what happens unless you guys think I'll have problems. Anyone happen to know the torque spec for the pan bolts?

    Decided to go the RTV route. That Permatex Trans pan sealer is a bear to get out of the tube!!! I think I pulled a thumb muscle!!!!:) Got everything finger tight right now and will be doing the final torque in an hour like the directions state. Fingers crossed she seals up OK!!!!!

    I did end up using the guide stud trick and it worked really well. I just cut the heads off two bolts and used them to guide the pan on.

    Still have a slight leak but it appears to be coming from a sensor mounted on the passenger side. Anyone ever have this issue and is it easy to seal up? Will I lose any Trans fluid if I pull it???

    passenger side would be the pressure sensor.
    wont loose much or any for that matter if you pull it out.

    yeah, I'm going to try to replace the o-rings.
    It's apparently non-serviceable unlike the other two sensors on the driver side.

    I assume this sensor is threaded into the trans case? Wouldn't a little teflon tape on the threads do the trick???

    I might try this tomorrow. Been doing it for a while but doesn't seem to drip if I'm parked level.

    The sensor does not thread into the tranny.
    It uses O-rings. the sensor is secured down with an external bolt to the tranny much like the CPS or CKS if you've replaced those before.
    It is not like the coolant temp sensor or the crankcase pressure sensor where it is threaded into the engine block.

    If you get around to it, please let me know the O-ring size you use.
    Wont be able to get to it this weekend.
    Thanks!
