What Does P075A Mean?
Shift Solenoid G in the automatic transmission has a general malfunction. The TCM has detected that solenoid G is not functioning within its expected operating range. Solenoid G is typically found in transmissions with 7 or more speeds and controls specific gear application. A malfunction can result in harsh shifts, missed gears, or limp mode activation.
Common Causes
35%
Failed shift solenoid G with internal electrical or mechanical failure
25%
Wiring fault in the solenoid G circuit between TCM and transmission
20%
Contaminated or deteriorated transmission fluid affecting solenoid operation
15%
Valve body issue affecting the hydraulic circuit controlled by solenoid G
5%
TCM software issue or hardware failure affecting solenoid G driver circuit
Diagnostic Steps
1
Review freeze frame data and all stored codes to determine if solenoid G is the only affected solenoid or if a broader issue exists.
2
Measure solenoid G resistance at the transmission connector and compare to the manufacturer specification.
3
Inspect the external transmission connector for signs of corrosion, damaged pins, or fluid intrusion.
4
Use a bi-directional scan tool to command solenoid G on and off while monitoring for proper response.
5
Check for TSBs related to the specific transmission — solenoid G issues may have manufacturer-recommended procedures.
6
If the solenoid is confirmed faulty, replace solenoid G and service the transmission fluid and filter.

The most common cause of P075A (Shift Solenoid G Malfunction) is: Failed shift solenoid G with internal electrical or mechanical failure
Typical repair costs for P075A range from $250 to $1,200, depending on the vehicle, location, and whether you do it yourself or go to a shop.
The vehicle may enter limp mode or fail to engage certain higher gears. Short-distance driving at low speed is possible, but the transmission should be repaired before normal driving resumes.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P075A to identify the root cause.
