tranny problems
I have a 06 3500 5.9 with an automatic. it is stuck in 2nd gear. I have had the gov solenoid changed and many other diagnostic things done the shop says its the ECM. Is this something that only can be fixed by the dealer? I have heard conflicting reports that the dealer is the only one the can flash a ECM? What is my best option?
