  • I have this code, 2008 Dodge Ram 1500 4.7l and this is the only code I have active. It's intermittent, when it's active the trucks slams into reverse,and only had high gear. Had it to the dealer twice, but didn't show the code when I took it there. One transmission shop claims it was the TIPM. I changed that and it wasn't it. The dealer wants to just start changing parts to see if it will fix it and I'm not doing that. But there positive it's an electrical problem.

  • Unfortunately, if the problem is not consistent, anyone will have hard time diagnosing the problem. You could either wait until the problem gets more consistent or try different parts. BTW, the service manual does not recommend replace the TIPM for that problem. See "Possible Causes" above.
