I aquired a 02 chev D/A 2500HD Crew cab long bed.
I pull a 12k 5th wheel. When working through the gears to highway speed, 4th gear winds up to about 2600rpm and shifts up to 5th gear and automatically goes into T/C lock up. That drops my rpm to about 1700 and then the engine sounds like it is groaning untill it gets up to about 2000rmp and then runs fine. Should there be a time when it shifts into 5th gear that it should start out in T/C unlock to help get the rpms higher and help you get past the low rpm engine groaning stage. once it gets to 2000rpm it runs great but it really drags at low rpms. This is all new to me so any help will be great.
