Pressure Control Solenoid 'D' Control Circuit Range/Performance
Code P2825 indicates that the Powertrain Control Module (PCM) has detected a range or performance issue in the control circuit of the pressure control solenoid 'D'. This solenoid regulates hydraulic pressure to the transmission clutches and bands for proper shifting. The fault may be due to electrical problems (open, short, high resistance) or mechanical issues within the solenoid or transmission.
01. Most Common Causes
- Faulty pressure control solenoid 'D'
- Wiring or connector issues (open, short, corrosion)
- Low transmission fluid level or dirty fluid
- Internal transmission mechanical failure
02. Symptoms You Will Notice
- Check Engine Light illuminated
- Harsh or delayed shifting
- Transmission slipping or stuck in gear
- Reduced fuel economy
03. Step-by-Step Diagnosis
Step 1: Scan for additional 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 connectors for damage, corrosion, or loose connections.
Step 4: Test solenoid resistance and power/ground circuits with a multimeter; compare to specs.
Step 5: If electrical tests pass, perform a transmission pressure test or solenoid actuation test with a scan tool.

05. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended. Driving with a transmission solenoid fault can cause erratic shifting, overheating, and potential internal damage. Have it diagnosed promptly.
How much does it cost to fix?▼
Repair costs vary. Replacing a solenoid can cost $200-$400 for parts and labor. If internal transmission damage is found, costs can exceed $1,500.
