What P2762 means
P2762 covers a solenoid circuit that is neither open nor shorted but does not behave as commanded. In GM's six-speed TCM tables for the MW7 (2016) and T87A (2018) the module compares desired with measured solenoid current; a gap of 0.5 A or more in at least 40 of fewer than 80 samples sets the code as Type B, with battery voltage above 10 V. For the T76 six-speed of 2016, GM instead calls it a rationality test that fails when the hardware layer reports an out-of-range voltage in 4.4 of 5 seconds, and lists it without MIL. Rising coil resistance, a weak supply or ground, or a current-sensing fault in the TCM are typical. Lockup may feel harsh or soft, since the pressure no longer follows the target.
P2762 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modeNot expected
- Repair difficultyMedium
- Typical labor0.5 to 5 hours
- Clears after repairAfter a drive cycle
Symptoms of P2762
- Harsh or slipping converter lockup
- Shudder at light throttle in higher gears
- Warning lamp depending on application (GM T76 none)
Common causes of P2762
- Most likelySolenoid coil resistance out of specification
- PossibleWeak supply voltage or poor ground at the TCM
- PossibleHigh-resistance terminal in the circuit
- Less likelyCurrent sensing fault inside the TCM
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2762 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 7 | Area: transmission. |
| 62 | The exact fault in that area. |
What to do next
- Note P2762 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P2762
What does P2762 mean?
P2762 means "Torque Converter Clutch Pressure Control Solenoid Control Circuit Range/Performance". P2762 covers a solenoid circuit that is neither open nor shorted but does not behave as commanded. It is a generic code, so it means the same on every make.
Is it safe to drive with P2762?
Usually yes, for a short time, if the check engine light is steady and the car drives normally. If the light flashes or the car runs badly, stop and have it checked.
Will P2762 fail an emissions test?
Yes, it can. P2762 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P2762 to fix?
Difficulty: medium. A typical repair takes 0.5 to 5 hours of work. This is a job for a workshop.
Will P2762 clear itself after the repair?
After the repair the car has to complete a drive cycle (a mix of city and highway driving) before the test runs again. Until then the readiness monitor shows "not ready", which can fail an inspection.
