P0757: Shift Solenoid B Stuck On
What Does P0757 Mean?
P0757 is a diagnostic trouble code indicating: Shift Solenoid B Stuck On. This code relates to the transmission system. It has been reported in NHTSA complaints across 4 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 P0757
- ⚠️ 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

"My vehicle began jumping when switching from drive to reverse. When I placed the car into reverse, it stalled and would not switch into reverse or neutral. The car stalled in the middle of a parking lot. The check engine light did not come on initially, and when it did, it did not remain on for very"
