How to Fix Error Code P2735
-
Read the Code and Check Freeze Frame Data
Do not clear the code without recording freeze frame data – it's critical for diagnosis. -
Inspect Transmission Fluid Level and Condition
Use only the manufacturer-recommended transmission fluid. -
Check Wiring and Connectors to Solenoid F
Disconnect the battery before working on electrical connectors. -
Test Solenoid F Resistance
-
Replace Pressure Control Solenoid F (if faulty)
Transmission fluid is hot and messy. Allow the transmission to cool. Use a drain pan and wear gloves.

When to Call a Professional
If you're not comfortable working with transmissions, or if the fluid is burnt (indicating internal wear), take the vehicle to a professional transmission shop. Also seek help if the code persists after solenoid replacement – the issue could be in the TCM or internal wiring harness.Frequently Asked Questions
Can I still drive with a P2735 code?
You can drive short distances, but it's not recommended. Intermittent solenoid issues can cause erratic shifting and may lead to transmission damage. Get it diagnosed as soon as possible.
How much does it cost to fix P2735?
Cost varies. DIY solenoid replacement runs $50-$200 for parts and fluid. Professional repair can be $200-$800+ depending on labor rates and if the solenoid pack requires transmission removal.
What does 'Pressure Control Solenoid F Intermittent' mean?
It means the transmission control module (TCM) detects an intermittent electrical problem in the circuit of the 'F' solenoid. This could be a wiring issue, a faulty solenoid, or a TCM problem.
Will a transmission flush fix P2735?
A flush may help if the code is caused by dirty fluid clogging the solenoid. However, if the solenoid or wiring is faulty, a flush alone won't fix it. It's best to diagnose the root cause first.
