Pressure Control Solenoid Intermittent
The P2735 code indicates an intermittent fault in the pressure control solenoid circuit, which regulates transmission line pressure. This can cause erratic shifting, slipping, or harsh engagement. The issue may stem from electrical problems (wiring, connectors, solenoid resistance) or internal transmission wear. Intermittent faults are often triggered by temperature, vibration, or moisture, making diagnosis challenging.
01. Most Common Causes
- Faulty pressure control solenoid
- Damaged wiring or connectors in solenoid circuit
- Low transmission fluid level or contamination
- Internal transmission mechanical failure
02. Symptoms You Will Notice
- Check Engine Light illuminated
- Erratic or harsh shifting
- Transmission slipping or delayed engagement
- Reduced fuel economy
03. Step-by-Step Diagnosis
Step 1: Scan for codes and record freeze frame data to capture conditions when fault occurred.
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 with a multimeter and compare to manufacturer specs.
Step 5: Perform a transmission pressure test to verify solenoid operation.

05. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended to drive long distances as intermittent solenoid failure can lead to transmission damage or sudden loss of drive.
How much does it cost to fix?▼
Repair costs typically range from $150 to $400, depending on whether the solenoid is replaced individually or as part of a transmission service.
