What P2764 means
P2764 is the low counterpart of P2763: the lockup solenoid circuit is pulled toward ground. GM's 2018 T87A table defines it as 0.01 Ω or less to vehicle ground, checked while the driver is off every 6.25 ms. In 2016, the T76 six-speed sets it on a ground-short flag in 4.4 of 5 seconds after a single trip, and the T54 CVT when the hardware sees a ground short for 480 ms or longer while lockup is on. FCA's remanufactured-transmission note for the 62TE adds a twist: if P0740 or P2764 come with jerking or slipping and the solenoid tests good, the torque converter itself has failed and must be replaced. Ford's 2012 6R80 also monitors its TCC driver under this code. Lockup is usually disabled until repair.
P2764 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyMedium
- Typical labor0.5 to 8 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P2764
- No lockup and higher fuel consumption
- Jerking or slipping (62TE)
- MIL after one trip on some GM units
Common causes of P2764
- Most likelyControl wire shorted to ground
- PossibleSolenoid winding shorted to its housing
- PossibleFailed torque converter when the solenoid tests good (FCA 62TE)
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2764 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. |
| 64 | The exact fault in that area. |
What to do next
- Note P2764 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 P2764
What does P2764 mean?
P2764 means "Torque Converter Clutch Pressure Control Solenoid Control Circuit Low". P2764 is the low counterpart of P2763: the lockup solenoid circuit is pulled toward ground. It is a generic code, so it means the same on every make.
Is it safe to drive with P2764?
Drive gently and only to a workshop. With P2764 the car can go into limp mode (reduced power) to protect itself.
Will P2764 fail an emissions test?
Yes, it can. P2764 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 P2764 to fix?
Difficulty: medium. A typical repair takes 0.5 to 8 hours of work. This is a job for a workshop.
Will P2764 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
