Pressure Control Solenoid Stuck On (P282A)
The P282A code indicates that the transmission control module (TCM) has detected a pressure control solenoid stuck in the 'on' position, meaning it is continuously applying pressure. This solenoid regulates hydraulic pressure to the transmission clutches and bands. When stuck on, it can cause harsh shifting, slipping, or transmission overheating. The issue is often due to internal solenoid failure, contaminated transmission fluid, or electrical faults.
01. Most Common Causes
- Faulty pressure control solenoid
- Contaminated or low transmission fluid
- Wiring or connector issues in the solenoid circuit
- Internal transmission mechanical failure
02. Symptoms You Will Notice
- Harsh or delayed shifts
- Transmission slipping
- Check Engine Light illuminated
- Transmission overheating
03. Step-by-Step Diagnosis
Step 1: Scan the vehicle for codes and record freeze frame data.
Step 2: Inspect transmission fluid level and condition; replace if dirty or low.
Step 3: Test the solenoid resistance and voltage supply using a multimeter.
Step 4: Perform a solenoid actuation test with a scan tool to verify operation.
Step 5: If solenoid fails, 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, overheating, and unsafe shifting. Have it diagnosed and repaired promptly.
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 labor for fluid flush and installation.
