Shift Solenoid G Stuck On
The P075C code indicates that the transmission control module (TCM) has detected that shift solenoid G is stuck in the 'on' position. This solenoid controls hydraulic pressure to a specific clutch or band within the automatic transmission. When stuck on, it can cause improper gear engagement, harsh shifts, or transmission slippage. The issue may be electrical (wiring, connector, TCM) or mechanical (blocked solenoid valve, contaminated transmission fluid).
01. Most Common Causes
- Faulty shift solenoid G
- Damaged wiring or connector to solenoid G
- Low or contaminated transmission fluid
- Internal transmission mechanical failure
02. Symptoms You Will Notice
- Check Engine Light illuminated
- Harsh or delayed shifts
- Transmission stuck in one gear
- Reduced fuel economy
03. Step-by-Step Diagnosis
Step 1: Scan for codes and record freeze frame data.
Step 2: Inspect transmission fluid level and condition; top off or replace if necessary.
Step 3: Visually check wiring and connector to solenoid G for damage or corrosion.
Step 4: Test solenoid G resistance and power/ground circuits using a multimeter.
Step 5: If electrical tests pass, remove transmission pan and inspect solenoid G for debris or sticking; replace if faulty.

05. Frequently Asked Questions
Is it safe to drive with this code?▼
Driving with P075C is not recommended as it can cause transmission damage or unsafe driving conditions. Have the vehicle towed to a repair shop.
How much does it cost to fix?▼
Repair costs typically range from $150 to $400, including parts and labor. Solenoid replacement is often $50-$150 for the part plus 1-2 hours of labor.
