What P0752 means
A shift solenoid is an electrically switched valve in the valve body; together the solenoid states select the gear, and the module checks the result by gear ratio, slip or a pressure switch – the pattern of wrong gears shows which solenoid hangs off or on. P0752 means solenoid A is commanded off but its clutch stays applied. GM's 6T70 flags slip of 400 rpm for 2 s five times after one trip and then runs only reverse, first and third with maximum pressure; GM's T43 a ratio of 3.83–4.23 (first instead of fourth); GM 4-speeds the pattern 1-1-4-4 after two trips; Allison its pressure switch after 2 s. Ford calls it 'functionally failed on'. A clutch that does not release can tie up the transmission.

Symptoms of P0752
- Wrong, often too low gear, engine revs high
- Tie-up or jolt on shifts
- Limp mode (GM: reverse, 1st, 3rd only)
- Check engine light
Common causes of P0752
- Most likelyShift spool sticking in the applied position
- PossibleSolenoid stuck open or leaking
- PossibleClutch not releasing (burnt or stuck)
- PossibleContaminated or wrong fluid
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |

| 52 | The exact fault in that area. |
What to do next
- Note P0752 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 P0752
What does P0752 mean?
P0752 means "Shift Solenoid A Stuck On". A shift solenoid is an electrically switched valve in the valve body; together the solenoid states select the gear, and the module checks the result by gear ratio, slip or a pressure switch – the pattern of wrong gears shows which solenoid hangs off or on. It is a generic code, so it means the same on every make.
Is it safe to drive with P0752?
Drive gently and only to a workshop. With P0752 the car can go into limp mode (reduced power) to protect itself.
Will P0752 fail an emissions test?
Yes, it can. P0752 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 P0752 to fix?
Difficulty: hard. A typical repair takes 1.5 to 12 hours of work. This is a job for a workshop.
Will P0752 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
