Tranny/ T-case question

I pulled out my tranny and t-case to do a slave conversion and noticed there is no gasket in the mating surface of the two. Should I rtv it when I put it back together? I called the local auto parts store and they said they don't show a gasket for it but it just seems wired that there isn't one. On the other hand it's never leaked fluid from there.

Also I have ax/5 manual w/ np207
Thx!

no gasket. There should not be any fluid in that area unless the shaft seal is leaking

There is actually a gasket between the transfer case and the transmission it comes in the transmission overhaul kit. The idea of the gasket is to keep dirt and debris out not to keep fluid in. If you don't have the gasket a bead of RVT silicone will work just as well.

Thanks, I put a small bead of rtv on it. After looking at the back side of the tranny I could tell there was a gasket in it at one time. Now on to a new problem I broke the master trying to drill it out to fit my jeep. Guess I'll start another post if I can't fix it.

It is true that a gasket is not required between the Tranny and the T case, and in all the tranny rebuild kits I have bought there is indeed a gasket that seems to be for this purpose. In all of the previously unmolested Tranny/T case combos I have pulled, I have never found a gasket or gasket remnants here. On my rebuilds, I never use the gasket, but they could come in handy as a "clocking ring" if anyone ever needs to redrill the extension housing of a tranny to reclock the T case. RTV isn't necessary here either. If you find any fluid between the Tranny and T case, you should replace the seals around the shafts and go from there.

Did you happen to take any photos of what you feel was a gasket remnant on the back of the tranny? I've just never seen one.

Sorry, no I didn't . I was just trying to get it done fast as I could. I just scraped it w/ a putty knife and wiped it clean. I think my jeep may have been molested a few times over. I paid a big tranny shop to replace the slave within the first few weeks of owning it. To my own ignorance I had them put an internal back in..... Live and learn right.
