- Faulty Transmission Control Module (TCM)
How do I fix code P1DF8 JEEP?
Check the “Possible Causes” listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins.
Cost of diagnosing the P1DF8 JEEP code

P1DF8 JEEP Description
The purpose of the diagnostic is to monitor if the Powertrain Control Module (PCM) executed the torque requested by the Transmission Control Module (TCM). This is determined by comparing the PCM’s executed torque to the original torque requested by the TCM over the Controller Area Network (CAN) bus. These torque requests only occur during shift operations. This diagnostic checks for engine torque reduction too high.
