P0757 on Pontiac
Shift Solenoid "B" Stuck On
P0757 on Pontiac vehicles indicates shift solenoid "b" stuck on. Au7o has documented this code across 1 Pontiac model — most commonly on Grand Prix. This code means the transmission control module commanded shift solenoid B to turn off, but it detected that the solenoid (or its hydraulic valve) is stuck in the ON/applied position. Shift solenoids control the flow of transmission fluid that engages different gears, so a stuck solenoid prevents the transmission from shifting correctly. You may notice harsh shifts, the transmission being stuck in one gear, or no shift at certain points. Continued driving can stress and overheat the transmission.
Common Causes of P0757
- •Failed or stuck shift solenoid B
- •Debris or contamination in the valve body
- •Dirty or degraded transmission fluid
- •Low transmission fluid level
- •Wiring or connector fault to the solenoid
- •Internal valve body wear or sticking
- •Faulty transmission control module (less common)

- 4T65-E Automatic Transmission Hard Shifting and Failure2001-2008
The exact corpus supports 4T65-E shift and failure conditions throughout the frozen 2001-2008 range, but not one cause. Examples include P0756/P0757 shift faults, P0741/P0742 TCC paths, pressure-control and valve-body work, second-clutch shudder, V8 torque-converter conditions, slips/no drive/reverse and code-specific valve-body reconditioning (including 10025065 for 2001-2008). The frozen accumulator, clutch-pack, solenoid and pan-magnet explanation collapses distinct unit/RPO, calibration, hydraulic, electrical and mechanical paths.

What does P0757 mean on Pontiac?▼
P0757 stands for "Shift Solenoid "B" Stuck On." This code means the transmission control module commanded shift solenoid B to turn off, but it detected that the solenoid (or its hydraulic valve) is stuck in the ON/applied position. Shift solenoids control the flow of transmission fluid that engages different gears, so a stuck solenoid prevents the transmission from shifting correctly. You may notice harsh shifts, the transmission being stuck in one gear, or no shift at certain points. Continued driving can stress and overheat the transmission. On Pontiac specifically, this code is documented across 1 model.
What causes P0757 on Pontiac vehicles?▼
