P0752 means Shift Solenoid A Stuck On. Shift solenoid A appears to be staying on when the computer commands it off, so the transmission does not change gear as expected. It is a generic OBD-II code, so the definition is the same on any make, but the most likely cause varies by engine; confirm with a scan tool and the service information for your vehicle before buying parts.
What P0752 means
Electronically controlled automatics are run by a transmission control module (TCM), a separate box or part of the engine computer. It reads speed sensors, the range sensor and fluid temperature to decide when to shift, and drives solenoids that apply clutches and the torque converter clutch. Many basic code readers only show the generic P0700; a scan tool that reads the transmission module shows the specific fault. Check fluid level and condition first, since low or burnt fluid causes many transmission codes.
P0752 symptoms
- Stuck in a gear
- Missing upshifts
- Harsh engagement
Common causes of P0752
- Sticking solenoid or valve from debris
- Contaminated fluid
- Wiring short keeping the solenoid powered
How to diagnose P0752
- Check transmission fluid level and condition first
- Command the solenoid off with a scan tool and watch the gear
- Check the circuit for shorts
- Inspect the valve body
Can you drive with P0752?
Only as needed until repaired.
P0752 tips
A solenoid that is stuck on is usually mechanical (debris or a sticking valve) rather than electrical. A fluid and filter change sometimes helps if the fluid is contaminated.
Will P0752 clear itself?
If the fault stops, the computer turns off the check engine light by itself after several drive cycles without seeing it again, and the code stays in memory as history for a while. Clearing P0752 with a scan tool after a repair is fine, but if the cause is still there the code returns, sometimes within one drive. Disconnecting the battery also clears codes on most vehicles, but it erases learned fuel trims and idle settings as well.

When it is more than a sensor
If the fault turns out to be internal (worn clutches, a failed converter or a damaged valve body), compare a rebuild with a replacement in transmission rebuild vs replacement and transmission replacement cost, identify your unit with what transmission do I have?, and browse our transmissions.
