As we speak my truck is at the dealer getting 3 new lines put in... the same 3 tranny lines that were done 1500 miles ago
, my best friend is a GMC salesman and says it's a common problem as they get them from a lousy suppler.as long as you own the truck they should pay to replace them, as it was a problem before the warranty was up.
So I'd check them every 1500 miles or at least every 3k oil change.
I had the steer shaft done also.
What do you expect for $47,000.00 anyways??
