What Does P075D Mean?
The electrical circuit for Shift Solenoid G has a fault. The TCM has detected an open circuit, short to ground, or short to battery voltage in the solenoid G wiring. This is a purely electrical fault code indicating the solenoid cannot be properly driven by the TCM, preventing the associated gear from engaging or disengaging correctly.
Common Causes
35%
Open or short circuit in the solenoid G wiring harness
30%
Shift solenoid G internal coil failure (open or shorted windings)
20%
Corroded or damaged transmission connector causing high resistance or intermittent connection
10%
TCM solenoid driver circuit failure
5%
Ground circuit issue for the solenoid pack
Diagnostic Steps
1
Measure solenoid G resistance at the transmission connector — an open reading or near-zero resistance confirms a coil failure.
2
Check for voltage at the solenoid G circuit at the transmission connector with the key on to verify the TCM is sending a signal.
3
Inspect the external transmission harness connector for corrosion, bent or pushed-back pins, and fluid contamination.
4
Perform a continuity and short-to-ground test on each wire in the solenoid G circuit from the TCM connector to the transmission connector.
5
If wiring is good and solenoid resistance is out of spec, replace solenoid G.

The most common cause of P075D (Shift Solenoid G Electrical) is: Open or short circuit in the solenoid G wiring harness
Typical repair costs for P075D range from $150 to $900, depending on the vehicle, location, and whether you do it yourself or go to a shop.
The transmission may default to limp mode. Driving at reduced speed to a repair facility is generally safe, but shift quality may be severely degraded.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P075D to identify the root cause.
