RTV Dry time - or use gasket
How long to really wait for RTV gasket maker to dry, before adding AT fluid?
Last time I changed tranny fluid, I'm sure I used RTV gasket maker silicone for the pan (don't remember a gasket).
I noticed the new filter includes a rubber gasket. Maybe should just use that?
Now, reading the package of Permatex Blue RTV, it says
* put the pan on while sealant's still wet
* finger tighten the bolts till sealant begins squeezing out
* let dry ~ 1 hr - then torque to specs
* allow drying 24 hours before filling w/ fluids or returning to service.
1) No shop or dealer waits 24 - or 3 - hours - if they use RTV at all.
2) Last time, I'm sure I wouldn't have waited 24 hours, but don't remember the exact time.
Thanks.

No, because I also use a gasket. I only use enough RTV to keep the gasket in place when reinstalling the pan or cover.
I know it goes against what we were all taught - never reuse a gasket - but in the case of Ford tranny pans just clean up the surfaces and reuse the original gasket as long as it's not damaged.

The Ford Factory transmission pan gasket is rubber bonded and is re-useable. DO NOT use the crappy gasket that came with the filter kit !!!!
If you need a replacement rubber bonded gasket, assuming you have a 4R70W, order it form here; http://www.transmissionpartsusa.com/...-0027141hd.htm
