P2735 code meaning
Pressure Control Solenoid F Intermittent
What P2735 means
By its standard title P2735 reports that solenoid F or its circuit fails only now and then, so a static check in the workshop often finds nothing. GM uses the code differently on the dual-clutch gearbox of the 2023 and 2024 Corvette: there valve F is the clutch cooling valve, and P2735 stands for a stuck lube valve. The TCM triggers a current-profile test on the valve during stable driving with fluid at 60 °C or warmer and a cooling flow target below 3 l/min; if the result keeps indicating failure, it sets the code. GM rates it Type C, so it does not switch on the MIL. Other makers do not document P2735 publicly. Intermittent wiring or connector faults on valve F are the generic reading, while the Corvette case points to the cooling valve itself.
P2735 at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyWorkshop only
- Typical labor0.5 to 8 hours
- Clears after repairAfter a drive cycle
Symptoms of P2735
- Often no noticeable symptom, code stored without MIL (GM)
- Occasional harsh shift or clutch judder
- Clutch overheating warning after hard driving
Common causes of P2735
- Most likelyClutch cooling/lube valve sticking (GM Corvette dual-clutch)
- PossibleLoose or corroded connector causing dropouts
- PossibleContaminated fluid affecting valve movement
- Less likelyHarness chafing that opens under vibration
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2735 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 7 | Area: transmission. |
| 35 | The exact fault in that area. |
What to do next
- Note P2735 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P2735
What does P2735 mean?
P2735 means "Pressure Control Solenoid F Intermittent". By its standard title P2735 reports that solenoid F or its circuit fails only now and then, so a static check in the workshop often finds nothing. It is a generic code, so it means the same on every make.
Is it safe to drive with P2735?
P2735 does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will P2735 fail an emissions test?
P2735 is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is P2735 to fix?
Difficulty: workshop only. A typical repair takes 0.5 to 8 hours of work. This is a job for a workshop.
Will P2735 clear itself after the repair?
After the repair the car has to complete a drive cycle (a mix of city and highway driving) before the test runs again. Until then the readiness monitor shows "not ready", which can fail an inspection.
