I recently had my tranny fixed and after it was fixed I drove 1100kms and my engine light went on which pointed to the governor or solenoid so I took it back in and the replaced the governor I go on another trip 2 weeks later and approx. 1200kms into my trip the engine light goes on again. so I stop and see if it is doing the same thing (take off being slow) and it is doing the same thing so I made it back and took the truck to the dealership they are saying it is my PCM that is showing an active failure so it needs to be replaced. my question is can the issues I was having on those 2 trips have cause my PCM to fail?

That's where diagnosis comes in: PCM's do fail on there own, and other components going to the PCM can fail causing the PCM to fail. The voltages are sent out to components and returned to the PCM. If these voltages are fed back at the wrong voltage it could damage it. Other reason as well, maybe you can understand this much.

so your saying yes it is possible?

I thought that as well but how do you prove that? impossible really. The original parts that I know were replaced were some bands of some sort and the Solenoid and the governor once it came out it worked good till it went out again and again I am fighting it because I don\t think I have to pay since their is no proof that the other components didn't cause the PCM to fail

Agree with the others. It is plausible, not that it does you any good at this time. A misdiagnosis should have been evident immeadiately and it isn't appropriate for them to have also done the module as a CYA when they did the other repairs. FWIW, governor solenoid failures are common and any failures cause the computer to turn the control solenoid relay off and you end up in limp in mode.

Actually it does do me some good because I told them not to fix it and contacted dodge directly because I really don't think I should be paying for it for the simple fact there is no proof that the other components didn't cause this, when I asked the service guy he even said it is possible so that to me means that it's not impossible therefore they should pay for it. I had to do 2000 kms in total on a failure that they failed to identify to me that extra stress on them parts may have caused it to fail. Maybe I am sucking wind here but I have to give it a try.
