Pressure Control Solenoid A Control Circuit Range/Performance
What it means
P0961 means the transmission control module sees the "A" pressure control solenoid responding outside its expected range. This solenoid regulates hydraulic line pressure for shifting, so a range/performance fault usually shows up as harsh, delayed, or slipping shifts rather than an engine problem. The engine still runs and starts normally.
Can I keep driving? Usually drivable, but expect harsh or delayed shifts and possible limp mode; get it looked at soon to avoid transmission wear.
Real-world scan data
Figures reflect only diagnostic scans recorded through our own apps and tools. Cars are typically scanned because a symptom or warning light prompted it, so these counts describe our scan records — not the incidence of faults in any model, and not the quality, reliability, or safety of any vehicle. No comparison between manufacturers or models is implied. All trademarks belong to their respective owners; no affiliation or endorsement is implied.
Common symptoms
What you'll notice
- Check-engine light on
- Delayed or harsh gear changes
- Transmission slipping or holding gears too long
- Transmission may drop into limp (fail-safe) mode
Common causes
Most likely first
- Failed pressure control solenoid ALikely
- Damaged wiring or connector in the solenoid control circuitCommon
- Loose or corroded electrical connectionsCommon
- Low or contaminated transmission fluid affecting hydraulic responseLess often
- Faulty transmission control module (TCM)Less often
How to diagnose & fix
Work through it in order
- Read freeze-frame data and check transmission fluid level and condition first.
- Inspect the solenoid wiring and connector for damage, corrosion, or loose pins.
- Measure the solenoid resistance and control-circuit voltage against spec.
- Replace the pressure control solenoid A if it is out of range.
- If wiring and solenoid test good, have the TCM diagnosed. Clear and road-test.
