OK for codes I got paid and p0731. 731 is gear 1 ratio incorrect. It slipped bad in gear 1 shifted to second and felt good. I assume the clutches I gear 1 are shot. Does anytime think so too
I have a 03 duramax. I am getting shift range inhibited. It feels like. The transmission is slipping in forward. Reverse works fine. Does it sound like the transmission is bad.
