P2764: Torque Converter Clutch Pressure Control Solenoid Control Circuit Low
A generic powertrain (engine and transmission) trouble code, same meaning on every brand.
Yes, moderately - typical result is the converter clutch staying unlocked: economy drops, heat rises, but the car drives. Watch the temperature and skip mountain grades and towing until fixed.
Symptoms
- RPM higher than usual at cruise
- Fuel economy down
- Possible shudder at steady speed
- Check engine light
Likely causes, most common first
- TCC solenoid circuit shorted low
- Solenoid coil failed
- Chafed wiring to the transmission
- Corroded case connector
Read P2764 yourself before paying for diagnosis
A basic Bluetooth OBD-II scanner ($20-40) plugs into the port under the dashboard and shows this code with live sensor data on your phone - useful both for confirming the fix and for talking to a shop from an informed position.
What is going on and how it gets diagnosed
P2764 is the electrical-low complaint for the torque converter clutch pressure solenoid - the computer sees a circuit reading beneath plausibility, meaning a short, a dead coil, or wiring dragging the signal down. Where its hydraulic sibling P2757 shudders, this one usually just gives up: the computer stops commanding lockup it cannot verify, and the converter slips at cruise full-time.
A slipping converter is not dramatic, but it is a heater - slip becomes heat in the fluid, and sustained heat is the great ager of transmissions. Hence the practical guidance: flat-land commuting is fine, prolonged grades and towing are not, and a temperature warning is a stop. Electrically this is the measurable kind of fault - solenoid resistance at the case connector against specification settles coil-versus-harness in minutes, the same happy property as the other electrical solenoid codes in this family.
Repair options and cost
Typical US independent-shop ranges, parts and labor. Dealers run higher; regional labor rates vary.
Owner reports mentioning P2764
“When I drove the car, All most all light on the dashboard are on onthe road, and when I stop and tried to go, the car is somewhat not controled.

“Cvt codes p0700 and p2764 came on. The dealership said that it needs a whole new transmission as fixing just the torque converter will not fix the issue. All warning lights came on and none of the safety features will work. The car was doing this from a starting point and stayed on no matter speed.
