Okay it been about a month since i got my truck back from the dealer. They had to replace the tranny due to the rear bearing falling causing the case to crack. Today i was getting ready to install my muffler delete pipe and noticed a bunch of oil on the under carriage. So i traced it up to the back of the tranny where it conects to the t-case. Does anyone have an idea what could be the problem. its a 2007 ctd quad cab 4x4 w/ 6spd.
