Trans pan gaskets?

[Lakota]

So far I've changed the gasket on my TH350 trans three times and they all leaked. The last time I changed the pan and the gasket. Normally I use a cork gasket with the red goop sealant. What do you guys use?

I've always used the re-usable rubber gaskets with no problems.

I don't follow instructions when do this. I put a VERY THIN layer of black gasket sealer on both sides of the gasket, then tighten the bolts. I know you are not supposed to use sealer on both sides of the gasket, but I do it anyway and it works for me. Never had one leak.

I use the clear silicon gasket sealer on the gasket. I snug the pan bolts down. Let it sit overnight and re-snug the bolts.

If it still leaking,Take the pan off,Flip it over and go over the entire bolt flange with a light hammer or rubber mallat.The flange is probably warped from being over torqued.Then use light silcone on pan and both sides of gasket.Let dry and then refill.You should be ok.

if the pan is the chrome kind, get rid of it. problems up the wazzzoooo.

get a felpro gasket, not the cork one they make but the blue rubberish one...and some of the black form-a-gasket stuff and put about an 1/4 inch tall bead between the gasket and trans

you could do both sides of the gasket just to make sure there are no leaks but there really isn't any need to.

tighten down bolts...let sit 24 hrs then retighten and go have fun!

The chrome pans work IF you wire wheel the chrome off the lip so that the sealant has something to stick to. Otherwise the sealant just squishes out when you tighten it.
I'm using a stock pan, but I think this time I'll use the rubber type of gasket instead of the cork. The cork never seems to fit right. I'm also thinking about using a contact cement between the pan and the gasket, to keep it in place when I tighten it. Thanks for the tips guys

Those pans warp easy if you use a screwdriver to pry them off. I use a putty knife or something thin.

Maybe that's my problem. Mine never stick. I have to hold the pan while I undo the last two bolts.

Another thing that can cause problems with sealing is over-tightening the bolts. I don't know the torque specs for that trans, but they should be followed. Find them in your repair manual.

C'mon moto, you're takin all the fun out of dropping a tranny pan. . The fluid shampoo is traditional.

i dont mind all the tranny fluid on my head......its all the metal shavings that makes me itch lol

Drain plug??? I usually insert a long hose and suck all the fluid out. I really should buy some sort of a pump to get it out, it gives me the runs for a whole week.
