P2724 - Pressure Control Solenoid 'G' Stuck On
The P2724 code indicates that the Powertrain Control Module (PCM) has detected the pressure control solenoid 'G' (part of the transmission valve body) is stuck in the 'on' position, meaning it is continuously applying pressure to the hydraulic circuit. This solenoid regulates line pressure for clutch application; when stuck on, it can cause harsh shifts, slipping, or transmission overheating. The issue is often due to internal solenoid failure, contaminated transmission fluid, or wiring problems.
01. Most Common Causes
- Faulty pressure control solenoid 'G'
- Contaminated or degraded transmission fluid
- Short circuit or open in solenoid wiring/harness
- Internal transmission valve body damage
02. Symptoms You Will Notice
- Harsh or delayed shifts
- Transmission slipping or overheating
- Check Engine Light illuminated
- 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; replace if burnt or contaminated.
Step 3: Test solenoid 'G' resistance and power/ground circuits with a multimeter.
Step 4: Perform a transmission pressure test to confirm solenoid operation.
Step 5: If solenoid is faulty, replace it and flush the transmission fluid.

05. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended. Driving with a stuck solenoid can cause transmission damage, slipping, or overheating. Have it diagnosed and repaired promptly.
How much does it cost to fix?▼
Repair costs typically range from $150 to $400, including parts (solenoid and fluid) and labor. If valve body replacement is needed, costs can exceed $1,000.
