When I picked up the truck for Pro-Tech originally, after the first repair, I didn't drive more than 50 clicks before I had transmission fluid everywhere. It was a mess! I guess the housing was cracked or something like that. So the first try it was not too good. After a weekend off, when I was not really able to drive my truck because I was worried I would lose to much liquid, I brought it back to the shop again. The second try went very well. I don't see any leeks or anything. As for the service, for $2000 they were friendly enough and tried to help me out, but again the first try was not so good.
