P0761 Shift Solenoid C Performance/Stuck Off

EmissionsRelevant

A shift solenoid is an electrically switched valve in the valve body; the module checks whether its clutch follows the command by gear ratio, shift time or a pressure switch. P0761 means solenoid C is commanded on but its clutch does not follow. GM's Honda-built five-speed (Saturn Vue) combines a ratio check – first gear running in the window of second for 1.2 s – with a 3–4 shift faster than 0.8 s, after two trips. The 2007 Allison 1000 checks pressure switch 3 for 5 s, after one trip. Ford's 'functionally failed off' covers the CB26 brake circuit; Dodge's Aisin AS6 uses the code for solenoid 3, while Mitsubishi uses it for pressure switches.

Likely causes

Clutch or brake of this circuit leaking or worn (piston seal, linings)
Shift spool or proportional valve sticking (dirt, debris)
Fluid level or quality
Pressure switch faulty (Allison, Aisin)

Symptoms

  • Gears missing or skipped
  • Slip or engine flare on shifts
  • Limp mode
  • Check engine light
