I've replaced the transmission pan two times already. The first time the generic gasket had holes that were misaligned and it wrinkled and leaked. Badly.
So I bought some fresh black RTV, cleaned everything up really well, applied the RTV to the pan, let skin over for 15 minutes, cleaned off the sealing face as well as I could, then applied the pan without moving it around, tightened the pan bolts up to around 2-3 ft lbs, let cure for 2 hours, then finished torquing to the specified torque. This behavior has always worked for me when sealing with RTV. But I still have a very slow drippy leak, maybe 1-2 teaspoons per day.
I think that the problem was that I let the tranny drip for "only" 4 hours before reinstalling the pan. But it was still dripping slowly. I wiped up inside as far as I could and hurried to get the pan on, but I'm sure that a tiny bit of ATF dripped down in the 10 seconds it took me to mount the pan.
So, I bought a tube of Chrysler ATF RTV. I'm scheduled to drain and replace the pan again. But I don't want to do it and get the same results. I may let the pan drip overnight this time, but if it's still slowly dripping, what can I do? How long do I have to wait for the system to stop dripping? Forever? Will the torque converter, cooling lines, etc. keep dripping for a long time?
Really, I just want to do it right this time, without leaks. So if I had an idea of how long is long enough, that would help. Or is the ATF RTV less susceptible to this kind of contamination of the surface with some liquid ATF? (I cleaned before with a paper towel sprayed with brake cleaner).
Also, the Chrysler tube says to just apply, install and torque. Is there no time for skinning the RTV before installation or set time before final torque?
