Shift Solenoid G Stuck On

What Does P075C Mean?

Shift Solenoid G is mechanically stuck in the on position. The TCM detects that solenoid G remains energized or that the gear ratio it controls stays engaged when it should be released. This can cause the transmission to stay locked in an incorrect gear, create bind-up conditions between gears, or produce very harsh downshifts.

Diagnostic Steps

1

Check live data for the gear solenoid G controls — verify it remains engaged even when the TCM commands it off.

2

Disconnect solenoid G electrically and check if the stuck-on condition clears, indicating an electrical vs. mechanical issue.

3

Measure solenoid G resistance and check for a short to power in the wiring circuit.

4

Inspect the transmission valve body for a stuck shift valve in the solenoid G hydraulic circuit.

5

Replace solenoid G and service transmission fluid if contamination is present.

What causes P075C?

The most common cause of P075C (Shift Solenoid G Stuck On) is: Shift solenoid G mechanically stuck open due to debris or internal spring failure

How much does it cost to fix P075C?

Typical repair costs for P075C range from $300 to $1,400, depending on the vehicle, location, and whether you do it yourself or go to a shop.

Is it safe to drive with P075C?

A stuck-on solenoid can cause gear bind-up or prevent proper downshifting. This creates unpredictable driving behavior. Limit driving to reaching a repair facility and avoid high-speed roads.

How do I diagnose P075C?

Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P075C to identify the root cause.
