P282A Pressure Control Solenoid K Stuck On

P282A reports the reverse of P2829: K holds the selector mechanism in its pressurized state after being switched off. GM's 2023 Corvette dual-clutch software uses the same synchronizer integrity routine, this time with a test case whose selector target is hydraulic off. When the measured rod motion matches the on position and the selector pilot valve's current profile check keeps failing, the TCM blames the pilot valve rather than the selector spool and stores a Type A fault. Ford's TR9070 summary lists the matching stuck-on case for its selector pilot valve as P27DA. A pilot valve hanging open may route pressure to the wrong shift rod, so the controller can lock out gears or choose a limp mode. Dirty fluid and worn valve bores are the usual mechanical reasons.

Likely causes

Selector pilot valve stuck in the applied position
Worn valve bore causing internal leakage
Contaminated fluid jamming the valve

Symptoms

  • Gears locked out or limp mode
  • Clunk or unexpected rod movement during shifts
  • MIL on
