97 chev tahoe transmission/transfer case

[tahoe]

hello folks. new here.
I just found this site and think its great so far. I have a 97 chev tahoe sport 4x4 that I bought 3 years ago. I love the truck but seem to have issues with the transmission. I had to replace the transmission 2 years ago and felt rather burned on that one but it has been great since except on a recently trip to get it serviced - the mechanic was going to repare a seal on the transfer case and it fell out of his hands. The dealership replaced with a new one but now the truck is leaking transmission fluid. Can anyone tell me if this would be related to the repair? Any advise would be much appreciated. Cheers, Stephanie - aka tahoe (kacoa@hotmail.com)
