P2732 Pressure Control Solenoid F Performance/Stuck Off

P2732 says that the clutch behind valve F does not take up torque although the solenoid works electrically, so the gearbox slips wherever that clutch is needed. On GM nine-speed units valve F serves clutch C6; the TCM counts a failure when C6 slip stays at 200 rpm or more for 3 s, and three such events give a Type A fault after one trip (tables 18OBDG04 and 20OBDG03A). GM bulletins name the code solenoid valve 6 stuck off. On the 10L80 in 2024 Silverado and Sierra 1500, PIP6002 and 24-NA-181 replace the valve body, and 25-NA-014 and 25-NA-080 trace the loss of reverse and of gears above third to a wrongly stamped spacer plate together with a worn check ball. On the 10L1000 with the 6.6 gas engine, 24-NA-148 pairs P2732 with P2714 and a worn C4 piston seal.

Likely causes

Mis-stamped spacer plate or worn check ball in the valve body (GM 10L80)
Worn clutch piston seal losing apply pressure (GM 10L1000)
Solenoid F or regulator valve sticking closed
Low fluid level or aerated fluid

Symptoms

  • No reverse
  • Transmission will not shift beyond third gear
  • Slip or flare and MIL on
