Transmission Control Module (TCM) MIL Request Circuit

There is a DTC look up sticky at the top of this forum. Beyond what it says, I have no idea. Sounds like an issue in the TCM.

My invoice from dealer says same code. This is probably how they know I have a tuner in it. But they reset tcm and its fine. You can reset it with your tuner also. Drive it calm and let tcm relearn.
