P0761 on GMC
Shift Solenoid 'C' Performance or Stuck Off
P0761 on GMC vehicles indicates shift solenoid 'c' performance or stuck off. Au7o has documented this code across 1 GMC model — most commonly on Sierra 1500. Set when shift solenoid 'C' does not respond as commanded or is stuck off, so the gear engagement it controls does not occur properly. Typical repair costs on GMC range from $600 to $2,500, depending on the specific model and root cause.
Common Causes of P0761
- •Shift solenoid 'C' stuck off
- •Debris in valve body
- •Low/contaminated fluid
- •Wiring resistance
- •Worn solenoid

- P0700 — Transmission Fault Flag from Failing 6L80/6L90 Internal TEHCM2007-2018
P0700 itself is only a flag: the Transmission Control Module has stored one or more transmission faults and is requesting the MIL. On Sierra 1500s with the 6L80 (and 6L90 on heavier variants) 6-speed automatic, the notable design issue is that the TCM is integrated into the valve body as a TEHCM (transmission electro-hydraulic control module), bolted inside the pan and sitting in 180-250°F fluid. Repeated heat cycling degrades the module and its integrated pressure switches and solenoids. When the TEHCM or a shift/pressure-control solenoid begins to fail, it sets specific sub-codes (e.g., P2534, P0742, P0761) plus the umbrella P0700, and the truck can exhibit harsh or missed shifts, slipping, or limp mode. Critically, on the 6L80/6L90 the solenoids are over-molded into the non-serviceable TEHCM and generally can't be replaced individually.
