P07F2 — Transmission Range Control Module Communication Circuit
General fault on the communication line between the TCM and a separate transmission range control module (used on systems where the rotary/push-button selector lives in its own intelligent module that talks to the TCM via CAN or LIN).
General code reference. Confirm the definition and diagnostic procedure for your vehicle's year, model and engine. A stored code alone does not identify a failed part.
Affected components
- Range control module
- Communication bus
Possible causes to check
These are possible checks, not a ranked diagnosis. Follow the vehicle manufacturer's test procedure before replacing parts.
- Bus fault between modules
- Failed range control module
- Gateway module routing CAN messages incorrectly
Possible symptoms
- Check engine or transmission warning light on
- Harsh, delayed, or missing shifts
- Possible limp mode (locked in one gear)
- Slipping or shuddering during gear changes
Diagnostic notes
- The malfunction indicator lamp may illuminate

Check each reference's vehicle and model-year scope. General background links do not establish which fault is most likely on your vehicle.
Diagnostic information is provided for reference only. Confirm the code with a compatible scan tool and follow the vehicle manufacturer's service procedures before replacing components.
