Silicone RTV on Trans Pan Gasket

Hello, I had my transmission serviced (E4OD) and noticed that when the pan was reinstalled, a lot of silicone sealant was placed between the pan and the rubber gasket. Good bit squeezing out. Is this a bad thing? Never seen sealant used on an E4OD or 4R100. Thanks!

Just had my rebuilt a couple thousand miles ago. New seal leaked on mine so they put that stuff on mine as well----no leaks and no problems so far.

I would use permatex ultra black rtv or the permatex right stuff and/or permatex great stuff on EVERY gasket if I could..i hate cork gaskets..especially pan gaskets, which powerstrokes/idi's dont use(or shouldnt).

Seriously, they are all great sealants, and it is normal that it is squished out, not going to hurt anything. Its only bad if its leaking.

You don't need any sealant on the pan gasket, i have reused the same gasket 4 times. You will have some clean up on the next service, the filter will keep out any silicone that comes off.

Yeah, I wouldnt use sealant and a gasket.

Use one or the other is safe to say. I guess its preference on gaskets or sealant for some things

All this ranting going on, I dont think you need to do anything about it, troy

Thanks huge for the replies! I'll just drive it and not worry about silicone getting where it shouldn't. Thanks again!
