Thanks for the suggestions guys. I'll let you know if the tcase fixes it totally. |
Call Gmc and see if they will repair it .....even if your not the original owner they may do it if you cause enough stink. Cite the examples on their own web site about the case leaking problems due to factory defects and see what they say.....you got nothing to lose. I got a complete head gasket repair from Toyota by doing the same thing and I was the 3rd owner with 150,000 miles.
