Considering I have had seals replaced before, and the engine replaced, maybe someone stripped the 12mm and found that as a replacement. Lots easier IMHO.

Anyways, looks like the seals are leaking , and of course this is out of warranty, just wondering what the going rate/price is to have the TC seals replaced? It appears there would be lots of labor involved.

Im in Canada, and I got quoted $2500 from the Dealership and $1700 from a local mechanic. I think they said 15H labour?

Ive got a slow leak too, but not very much, so I just have the mechanic check and top up the TC fluid during oil changes, I will eventually have it fixed but I figure keeping an eye on it and topping it up should keep it going until I can afford to fix it.

I just did the Transfer Case and Rear Diff this weekend and can provide some tips on those fill bolts.

The TC fill bolt is a challenge to get to. I used a Craftsman dogbone wrench to loosen it and a stubby ratcheting flex wrench (flex to fit in there better) to unscrew it the rest of the way. Craftsman has a ratcheting dogbone, but it doesn't have 12mm on it. The dogbone wrench loosened the fill bolt very easily as it's a 6 point wrench with a lot of meat to it. It didn't require any liquid wrench.

For the fill bolt on the rear differential, there's a hole in the frame that you can insert your socket through. Doing so with a short socket extension, it was very easy to undo that bolt.

Hope this helps anyone having trouble with the TC or Diff.
