when codes are cleared you may get a few shifts out of it. When it shifts it shifts good.

Thank you for that information.

Basically, what those codes are telling me is that there is too much resistance on the circuit coming from the TIPM to the TCM, which is setting code P0882. Then, as the PCM (which is integrated with the TCM but has its own separate power and ground circuits) sees that, it sets P0700.

I can tell you that the fix from Chrysler is to replace the TIPM along with the harness. However, there's a chance you might be able to remove the TIPM and find and repair the cause of the high resistance - in most cases you'll find the connectors underneath corroded.

Please let me know what you find and if there's anything else I can help you with.

Best Regards.
