P0746: Pressure Control Solenoid A Performance/Stuck Off
What Does P0746 Mean?
P0746 is a diagnostic trouble code indicating: Pressure Control Solenoid A Performance/Stuck Off. This code relates to the transmission system. It has been reported in NHTSA complaints across 12 different vehicle models.
The automatic transmission is controlled by the TCM using input from speed sensors, temperature sensors, and pressure sensors. When the TCM detects a fault, it may activate limp mode (2nd or 3rd gear only). Shift solenoids are electromagnetic valves inside the valve body controlling hydraulic fluid flow. Modern transmissions use 4-8 solenoids in combination for each gear. Solenoid failures are often caused by contaminated fluid — worn clutch material and degraded fluid create varnish that sticks solenoids. Always check transmission fluid first: level, color (red/pink good, brown/black bad), and smell (burnt = internal damage). Transmission DTCs escalate fast — a $200 solenoid fix can become a $3000-$5000 rebuild if ignored.
Symptoms of P0746
- ⚠️ Check engine/transmission warning light on
- ⚠️ Harsh, delayed, or erratic shifting
- ⚠️ Transmission stuck in one gear (limp mode)
- ⚠️ No upshift or no downshift
- ⚠️ Transmission slipping
- ⚠️ RPM flares between shifts
Common Causes
- 🔍 Faulty shift solenoid
- 🔍 Contaminated transmission fluid
- 🔍 Wiring issue between TCM and solenoid
- 🔍 Valve body wear
- 🔍 TCM internal failure
