    Just trying to confirm something real quick - for a TH350...cork pan gasket = no rtv, just clean and bolt up...rubber pan gasket = rtv on both sides?

    I've never been a big fan of cork gaskets, but the risk of squeezing too much rtv into the tranny case kindof worries me, hehe.

    i'm not a fan of any silicone products in use with a gasket.. the slippery nature of silicone RTV doesn't jive well with either style gasket..

    i'm a proponent of gasket adhesives such as Hi-Tack, etc...

    I've always used cork and no sealant for the trans pan. Much easier to deal with if you change the filter once a year.

    I try to get the OE gasket at the dealership. I've always had problems with the ones from the parts stores. Ever since I started getting them from the dealership I haven't had a problem yet. :D

    If you don't go crazy with RTV, you don't have to worry about it. If you decide to use it, let it set up before installing, and let it sit and dry for awhile before you dump fluid in it.

    I'm not saying the trans filter is a preventative measure for overuse of silicone, but it IS there for a reason. :)

    I always used silicone on the pan side because I was too cheap to buy new pans every time I worked on a tranny. Even with straightening as best as you can, there is still the possibilty of leaks. Just have to learn that the bolts don't need 40ft lbs of torque, and a super thin smearing of RTV isn't going to hurt anything.
