Lets see your tricks for stopping that pesky trans leak
Hey guys,
I don't know about you but I have never owned a automatic trans that has not leaked. I just got mine rebuilt by a professional trans shop and it still leaks. Who has some tricks for stopping this problem?
Thanks in advance!

i'd take it back to the trans shop and have them fix the leaks, as for my camaro, I just put a rubber mat with some towels over it under the camaro, since it leaks maybe 1/4 quart a month.

thats not the problem. I should have clarified. The problem is with the pan gasket sealing.

If it was on real good, they might (or someone previously) may have bent the pan in getting it off.
If that's the case it might be a new $30 pan to take care of that problem....

how about burning a whole in the speedo cable, and having that leaking? lol i did that a while back. buddy told me the gear might not be seated, and centrifigual force was pulling fluid up the cable to the hole.
pulled the housing and reinstalled it, hasn't leaked since.
i also had a problem w/ my dipstick, that was a horrible mess. took it out and bent the bracket back, and then added about half a pound of rtv on the o ring and the tube and everything in between. that stopped leaking too, lol.
i know how you feel...

If it has one of those cork gaskets replace it with one of the rubber/neoprene not sure if thats how you spell it. I could never get the cork to seal, but the rubber one works great. I think the one i just bought from advance is made by pro king.

Mine is doing the EXACT same thing... now I know what the hell is going on now.
not really tricks just good assembly pratices. flaten out the bolt holes in the pan. i like something ( like high tack or rtv)to stick the gasket to the pan so it doesn't shift when i install the pan. don't over tighten the pan bolts. never install a seal dry. make sure the o ring doesn't get cut installing the dip stick.

If you ever have the tranny out, replace the pump to torque converter seal and the tail shaft bearing and seal. Got done installing a tranny and forgot to install a new pump seal and i had to deal with a tranny leak for about a year. probably why the thing went out on me too.
