    Ok, I think I have tracked down my tranny leak and I'm hoping it is this simple. My tranny pan gasket sticks out a hair all the way around the pan. I can squeeze it and see the fluid come out. Is this normal?

    The other place where I think it is leaking is on the driver side of the tranny pan, where the shifter goes into the tranny (I *think* it's the shifter...help here, I'm an idiot). I can see the fluid and I think it runs down onto the gasket and then spreads around the pan. Is this possible?

    Thanks! /forums/images/graemlins/grin.gif

    The tranny pan and gasket should be perfectly dry. Drop the pan and replace the gasket ( Dont forget to do the filter while you are in there )When you buy a gasket make sure it is flat and not folded up in a box.

    Hope this helps

    always use a felpro gasket never use a cork casket /forums/images/graemlins/thumb.gif oh and don't over tighten the bolts or you will pinch the gasket and it will leak /forums/images/graemlins/frown.gif

    better to spend a little money and get a higher quality tranny filter kit with a better gasket in it, try to snug all the bolts about the same but if you squeeze it so tight it is pushing the gasket out, then that is too much /forums/images/graemlins/eek.gif

    The shifter could be leaking. The seal can be replaced by dropping the pan, disconnecting the shift linkage and pulling the shaft out. The seal should be available from a tranny shop or a dealer.

    Try cleaning everything up and then checking it again in a day to track the leak down.

    There is nothing wrong with cork gaskets. I've used them before with no problems. In fact, if your pan isn't perfectly straight, cork is the way to go.

    Then again, I once had that problem. I fixed it permenantly by swapping out my automatic. /forums/images/graemlins/smile.gif Then my 4 speed leaked so I sealed it up with 2 tubes of silicone. (I definitely don't recommend this be done on an automatic!!)

    Can I get the felpro gaskets locally, at a Pepboys, Advance Auto Parts, NAPA??? I'm on their websites and I'm not seeing felpro.

    Oh, and thanks to all...exactly the info I was needing! /forums/images/graemlins/thumb.gif /forums/images/graemlins/thumb.gif /forums/images/graemlins/thumb.gif

    I agree.
    It's in the prep. It has to be absolutly oil free before you install the cork. I always wipe the surface the gasket seals to wil brake cleaner on a paper towel.

    77Jimmy, you might want to inspect the tranny fluid cooling lines that fit into the passenger side of the tranny. If there is a leak there it will drip down to the pan giving the illusion your pan gasket is leaking. and snug them pan bolts up!

    Mine seems to always be "juicy" and i've replaced it a few times and torqued the bolts to spec. Maybe it is a leak elsewhere, don't know.

    Anyone just use silicone and no gasket? This seems to work on other parts /forums/images/graemlins/1zhelp.gif
