P2761Torque Converter Clutch Pressure Control Solenoid Control Circuit/Open
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- How the car detects it
- P2761 says the TCM has lost continuity to the converter clutch pressure solenoid. GM documents the check in its six-speed TCM tables (16OBDG08 for the MW7 unit in Silverado/Sierra, 18OBDG04 for the T87A): with the driver switched off, an impedance of 173 kΩ or more counts as open, while 9.6 kΩ or less does not; after three hardware counts an intrusive test opens the low-side driver, and two confirming counts set the Type B code. The same tables block the stuck-off test P0741 while P2761 is pending. On 2023 Ram heavy-duty trucks with the 6.7 l Cummins, bulletin 1807223 lists P2761 among codes caused by a leaking capacitor inside the engine controller, so the solenoid is not always to blame.
- What you may notice
- No torque converter lockup
- MIL on after two trips (GM Type B)
- Higher cruise rpm and fuel use
- Likely causes
- LikelyBroken wire or backed-out pin to the solenoid
- PossibleOpen solenoid winding
- RareInternal controller fault (Ram 6.7 l ECM capacitor leak)
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
