P2737: Pressure Control Solenoid Control Circuit Range/Performance
The P2737 code indicates that the Powertrain Control Module (PCM) has detected a range or performance issue in the control circuit of the pressure control solenoid, typically for the transmission. This solenoid regulates hydraulic pressure for clutch engagement. The PCM monitors the solenoid's electrical feedback; if the actual current or voltage deviates from expected values, this code sets. Common causes include faulty solenoid, wiring issues, low transmission fluid, or internal transmission problems.
01. Most Common Causes
- Faulty pressure control solenoid
- Wiring or connector issues in the solenoid circuit
- Low or contaminated transmission fluid
- Internal transmission mechanical failure
02. Symptoms You Will Notice
- Check Engine Light illuminated
- Harsh or erratic shifting
- Transmission slipping or delayed engagement
- 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 up or replace if necessary.
Step 3: Visually check wiring and connectors to the pressure control solenoid for damage, corrosion, or loose connections.
Step 4: Test the solenoid resistance and compare to manufacturer specifications; replace if out of range.
Step 5: Perform a transmission pressure test to verify hydraulic circuit integrity.

05. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended. Driving with P2737 can cause harsh shifting, slipping, or transmission damage. Have it diagnosed promptly.
How much does it cost to fix?▼
Costs vary from $200 to $600 depending on the cause. Solenoid replacement is typically $150-$400, plus labor. Wiring repairs may be less.
