OBD-II Generic Error Code P2737: How to Fix It

Q: Can I drive my car with a P2737 code?

You can drive short distances with P2737 active, but it is not recommended for extended driving. This code often causes harsh shifting, gear slipping, or triggers limp mode, all of which can worsen transmission wear over time. Address the fault as soon as possible to prevent more costly damage.

Q: What causes the P2737 code?

The most common causes of P2737 include a faulty or stuck Pressure Control Solenoid F, damaged or corroded wiring and connectors in the transmission harness, low or contaminated transmission fluid, a clogged transmission filter, or in rarer cases, a failing transmission control module (TCM).

Q: How much does it cost to fix a P2737 code?

Repair costs vary widely. A simple fix like a wiring repair or fluid change may cost $50–$150 in parts. Replacing a pressure control solenoid typically runs $150–$400 in parts, plus $200–$500 in labor at a shop. If the TCM needs replacement or reprogramming, costs can reach $500–$1,500 or more depending on the vehicle.

Q: Will changing transmission fluid fix P2737?

If the code was caused by low, dirty, or degraded transmission fluid interfering with solenoid operation, a fluid and filter change may resolve the issue. However, if the solenoid itself is electrically faulty or the wiring is damaged, a fluid change alone will not clear the code permanently.

Q: Is P2737 the same as other pressure control solenoid codes like P2720 or P2731?

They are related but not identical. Codes in the P2720–P2740 range all relate to different pressure control solenoids (labeled A through F) in the transmission. P2737 specifically refers to Solenoid F's control circuit range issue. The diagnosis process is similar across all of these codes, but the specific solenoid location and wiring circuit will differ.

Abstract

The OBD-II error code P2737 indicates a problem with the Pressure Control Solenoid F control circuit being out of its expected range — typically inside an automatic transmission. This solenoid regulates hydraulic pressure to control gear shifts, and when its electrical signal falls outside normal parameters, the transmission control module (TCM) logs this fault. Left unaddressed, P2737 can lead to harsh or erratic shifting, transmission slipping, or even limp mode, so diagnosing it promptly is important.
