Truck Is in sig- recently had trans overhauled and threw p1740 TCC/OD solenoid- took it back and they replaced TC/OD solenoid and it took care of my issue for about 250 miles- CEL is back on and reading P1740 TCC/OD and now P0606 which looks like PCM- trucks is reining and shifting great have not had an issue- batteries were replaced last month- any thoughts?

 

Problem solved - turbo timer in slot 31 when it needed to be in 21
