P08D7 Shift Solenoid K Stuck On

Check engine lightOn
EmissionsRelevant
Drive cycleRequired
Limp modePossible

Stored when shift solenoid K is switched off but the circuit it feeds stays pressurised, so a clutch remains applied. No manufacturer documents this code publicly. GM's P0752 for solenoid A is the documented analogue: with third gear commanded, the TCM fails the valve when gearbox slip reaches 400 rpm while the transmission actually sits in first or second, and the MIL lights after a single trip. Ford flags stuck-on solenoids from the gear actually reached during its mechanical check. CARB demands this functional monitoring. P08D6 is the opposite fault, P08D8 and P08DA to P08DD the circuit faults. Drivers may notice a wrong starting gear, binding, harsh engagement or emergency mode.

Likely causes

Valve or shift spool jammed in applied position
Metal debris in the fluid after internal wear
TCM output or shorted wire keeps the solenoid energised

Symptoms

  • Check engine or transmission warning light on
  • Wrong gear when pulling away
  • Binding or harsh engagement
  • Limp mode
