P2737
Pressure Control Solenoid F Control Circuit Range/Performance
Automatic transmission (pressure control solenoid)
Generic OBD-II
Medium
What it means
P2737 means the transmission's pressure control solenoid 'F' circuit is working but reading outside its expected range, so line pressure isn't what the module commands. That leads to harsh shifts, slipping, or limp mode. Common causes are a failing solenoid, dirty fluid, or a wiring/valve-body issue — the engine still starts and runs.
Medium
Can I keep driving? Yes but with care — out-of-range line pressure can cause harsh shifts, slipping, or limp mode; extended driving risks transmission wear, so repair soon.
Common symptoms
What you'll notice
- Harsh or erratic shifts
- Transmission slipping or flaring
- Limp mode (fixed gear)
- Check-engine light on
Common causes
Most likely first
- Faulty pressure control solenoid F (out of range)Likely
- Dirty or contaminated transmission fluidCommon
- Wiring or connector fault raising circuit resistanceCommon
- Internal hydraulic leak or blockage in the valve bodyLess often
- Transmission control module fault (least likely)Less often
How to diagnose & fix
Work through it in order
- Check transmission fluid level and condition first.
- Inspect the solenoid connector and internal harness for resistance or corrosion.
- Back-probe and measure solenoid F resistance and commanded vs. actual response.
- Service the valve body/internal harness if discrepancies are found.
- Replace the solenoid if it fails; consider the module only after checks pass.
FAQ
Quick answers
Is it safe to drive with P2737?+
Short-term, gently. The transmission may shift harshly or slip. Because slipping wears the transmission, get it diagnosed soon.
Can I just clear P2737?+
You can, but a failing solenoid or wiring fault will bring it back. Check the fluid and connector before clearing.
