    A little grease can help it stick...I think that was already suggested. Also, easy on the tightess. Tighten bolts in a cross pattern to avoid bending the pan.

    Why would putting a little gasket sealer on the tranny gasket to hold it is place cause transmision problems?

    Just like silicone can clog oil pump pickups, it can plug up transmission pickups.

    I hate silicone period, but in some places you just have to use it. A tranny gasket isn't one of them.

    I am simply offering my opinion. I'd take the pan down and re-do it.

    If you used the Perma-tex #2 brown goo it will be fine so long as you just brushed a light coat on it.
    I use High tac on gasgets, the spay kind.

    Transmission gaskets dont require anything now days. Just put the gasket on there and tighten up the bolts till you see the gasket start to smash out. Transmission oil will eat through silicon after awile and start to leak and can plug your tranny.

    Not a big deal. Let it be for future reference.

    do not use any sealent ,
    not only will the tranny fluid eat through
    the sealent , but you also take a chance on getting some
    of it floating around in your tranny and wasting it.

    i remember the fist time i used sealent along with the gasket ,
    and i drove thr miles , went and watched my son play ball ,
    then went back to a huge puddle under my truck.

    Well what do you use to get the gasket stay on the pan? It was impossible before I put the gasket stuff on to hold it. Should I redo it with grease? any other suggestions?

    Don't worry about it unless it leaks. Period the end. I've heard it both ways as well. In a perfect world, no gasket or sealant would be needed, the surfaces would be perfectly smooth, and no fluid would leak with a metal to metal finish. It's not a perfect world, and stuff leaks. If you can get it to leak without silicone or sealant, great! If you can't, use the stuff, just be careful of how much and where you use it.

    I've tried both ways on all the trannies I've worked on, with silicone, I typically have no leaks, without, sometimes I do. I use it on the diff cover as well, and same as the tranny pan, you'll hear tons of different ways that are "right". What they are, are ways that have worked for people.
