DIY M6 seal change
Has anyone attempted? If so, any tips or cautions? My tranny is leaking at the rear case seal; seems to be worse at high(er) temps.
Looking for your thoughts!
Also, can anyone recommend competent dealer service shops in the Columbus, IN to Indy, IN area?
Thanks!

Re: DIY M6 seal change (XS)
I did mine myself a little over a month ago and seems to be holding up pretty well. Mine was leaking at the first seal in front of where it mounts to differential. I had it resealed once under warranty only for it to leak again about 5,000 miles later when it was out of warranty.
It was pretty easy, but it took me a while to get it done. Here's what I did:
I put the car up on 4 jackstands
Drained tranny fluid
Unbolted diff from subframe (two bolts beneath it)
Unbolted the tranny at the leaking area
Then I just pulled the diff back to split the tranny open, leaving a couple of inches to work with (I also had a jack supporting front part of tranny)
Cleaned the surfaces with degreaser
Applied factory GM sealant on the surface, a little thicker and heavier than the existing seal was
Bolted everything back together and waited a little while to let cure
Filled tranny up with Mobil One Synthetic and haven't had a problem since
I know this probably isn't the way you're supposed to do it, and I didn't torque everything back exactly (no room for torque wrench), but heck it works with no problems.
