Need help sealing Transfer Case to Transmission

[YukonRog]

My memory isn't the greatest but I think this area is supposed to be dry and only becomes fluid filled when one or the other seal fails. Precision Transmission's youtube videos talk about this relationship as does the shop manual.

Yeah I've watched a lot of videos lately. Like that guy Richard. Is he ill or retired now? How about a photo of that page from your manual buddy?

Richard is around. He was off for surgery and a vacation but he's back to work.



No difference between tail adapters, same o-ring and seal.

Hey Thanks! Glad to hear he's okay. He's a good ol boy. And I like pictures. Kinda what I expected though. Poor design in my mind. I believe they put a seal in with a snap ring on the 6L80E?

I don't recall.

Pretty funny, I just watched that video a couple hours ago! This is not a great photo, but it shows the snap ring holding the seal in a 6L80E. Waay better idea.

So just going over some things, I found this write up and I believe there's a typo at the end where he recommends the ATF fluid type. It says Dexron III, or IV. Shouldn't it be VI? What do you think?

If the write up is old enough, maybe Dexron VI was not out yet. I used Dexron VI and it covers all the preceded it.

If you have the NVG246 transfer case it takes Auto Trak II fluid. Your owner's manual should list what it takes.

Yes Sir, I found this (attached) so it was correct I guess. For a time, you could use IV. I saw it as a typo for VI. Which is backwards compatible.

Dexron IV was an upgraded version of Dexron III, which was used by GM only briefly. ... It is also the specified ATF in certain non-GM models that use GM transmissions, such as BMW.
