Pressure Control Solenoid "F" Control Circuit Range/Performance
P2737 indicates the transmission control solenoid F is not operating within the expected range or performance parameters. This solenoid controls transmission fluid pressure and gear shifting; when it fails, the transmission may enter limp mode and shift improperly.
What You Might Notice
- Check Engine Light illuminated
- Transmission slips or hesitates during shifts
- Hard or harsh shifting (banging into gear)
- Increased fuel consumption
- Transmission overheating
Most Common Causes
- 1
Faulty Pressure Control Solenoid F
The solenoid coil is damaged, stuck, or has failed electrically. This is the most common cause and requires solenoid replacement.
- 2
Wiring or Connector Issues
Corroded, loose, or damaged wiring and connectors to the solenoid prevent proper electrical signal transmission.
- 3
Low or Contaminated Transmission Fluid
Insufficient fluid level or dirty fluid reduces solenoid responsiveness and causes shifting problems.
- 4
PCM or Transmission Control Module Fault
A malfunctioning engine or transmission computer may send incorrect signals to the solenoid or misinterpret feedback.
How to Diagnose It
- 1
Check Faulty Pressure Control Solenoid F — The solenoid coil is damaged, stuck, or has failed electrically. This is the most common cause and requires solenoid replacement.
- 2
Check Wiring or Connector Issues — Corroded, loose, or damaged wiring and connectors to the solenoid prevent proper electrical signal transmission.
- 3
Check Low or Contaminated Transmission Fluid — Insufficient fluid level or dirty fluid reduces solenoid responsiveness and causes shifting problems.
- 4
Check PCM or Transmission Control Module Fault — A malfunctioning engine or transmission computer may send incorrect signals to the solenoid or misinterpret feedback.
How to Fix It
- 1
Replace Pressure Control Solenoid F
Remove and replace the faulty solenoid with a new or remanufactured unit. Verify proper wiring and connector installation.
- 2
Inspect and Repair Wiring
Check all wiring harnesses and connectors for corrosion, breaks, or loose connections. Repair or replace damaged sections as needed.
- 3
Flush and Service Transmission Fluid
Perform a complete transmission fluid and filter change to remove contaminants and restore proper solenoid operation.
- 4
Reprogram or Replace PCM/TCM
If solenoid and wiring are functional, the transmission control module may need reprogramming or replacement by a qualified technician.
