To diagnose the P1DF3 code, it typically requires 1.0 hour of labor. The specific diagnosis time and labor rates at auto repair shops can differ based on factors such as the location, make and model of the vehicle, and even the engine type. It is common for most auto repair shops to charge between $75 and $150 per hour.
The purpose of the diagnostic is to monitor the time period of the Electronic Shift Module (ESM) initialization state. The Transmission Control Module (TCM) receives the status of the initialization state from the ESM on the Controller Area Network (CAN) bus while evaluating a counter in the TCM to determine if the initialization time is excessive.
