Title: Transfer Case Leak
Post by: yakimarcher on July 12, 2011, 12:43:08 PM: After a weekend of hard scouting for early season elk i came home to find a pretty bad leak coming from where the trans meets the transfer case in my 95 yukon. I haven't driven it since, i has hoping someone on here could shed some light on possible causes for this problem, my buddy and I are going to try to fix it this weekend.

Me too! Have it done at a shop, you will be better off in the long run and you won't end up with an ATF bath.

I checked the trans fluid on friday in Yakima, drove up to raven roost and back to Yakima, on saturday i went back up to the then went to Tacoma to see Ted Nugent, then I stayed at my buddys house in Everett and drove home sunday morning. well over 500 miles driven without losing any fluid.

There isn't an output seal on a 4L60e-4L80e 4x4 transmission, the leak is in your transfer case.

The fluid leaking is from the transfer case. It is seperate from the transmission. Like FC said, the transfer case is leaking, not the transmission. There's a seal keeping the fluid in the t-case and another seal keeping the fluid in the transmission. 2 seperate fluids although I think they're both ATF(the same type of fluid in both).
