P0757 on Pontiac by model: symptoms, diagnosis and fix
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.
Common Symptoms
- transmission RPO identified
- codes and operating conditions captured
- fluid, debris, cooler flow and pressure checked
- electrical, hydraulic, converter and clutch paths separated
How to Fix
Identify the transmission by VIN/RPO and capture codes, freeze-frame, commanded/actual gear, shift timing and temperature. Inspect fluid/debris, cooler flow and line pressure, then follow the code- and unit-specific tree before solenoid, valve-body, converter, clutch or unit replacement. Do not buy a solenoid, valve body, clutch kit, accumulator, magnet or transmission from this page; unit/RPO, failed path, calibration, part number and VIN fitment must be established first.

Frequently asked questions
What does P0757 mean on a 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 it is documented across 1 model: Grand Prix.
What are the most common causes of P0757?
The most common causes of P0757 are: 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). The specific cause varies by vehicle.
How much does it cost to fix P0757 on a Pontiac?
Repair costs vary widely with the root cause and Pontiac model; each issue on this page carries its own estimate where one is published.
