anybody had trouble with tranny in 2008 ext/cab 4x4 with 5.3? It seems as though it is slipping going from 1st to 2nd and also from 2nd to 3rd, the truck will rev to 3,000rpm and then slips in not a deffinent shift. Reason I think slipping is due to the brownish red tranny fluid. The truck has 85,000kms and was fine when first purchased 2 months ago. Really bad when towing last night. Any suggestions????
