P2725 covers an unspecified electrical fault of pressure control solenoid E. The driver notices a coil current or voltage that does not fit the command but does not classify it further. No manufacturer documents P2725 publicly. GM splits the electrical checks of valve E into P2727, P2729 and P2730; on the Allison 1000 these are Type A tests on the solenoid GM calls PCS 1, including a ground-short check every 6.25 ms. Ford's 2024 summary uses the same three codes for its TR9070 line pressure pilot valve. CARB demands circuit monitoring of transmission solenoids. A controller using P2725 would point to the same suspects: coil, connector, harness or driver. Depending on the gearbox the result is a default gear or a pressure fallback.

Likely causes

Faulty coil in solenoid E
Corroded or loose connector
Damaged wiring between TCM and solenoid
Defective TCM output stage

Symptoms

  • MIL lit and default gear
  • Firm shifts from fallback pressure
  • Code returns at once if the fault is permanent
