P0757 on Pontiac by model: symptoms, diagnosis and fix
The 4T65-E in 2001-2008 Grand Prix models has several different shift and failure conditions, not one single 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). A single accumulator, clutch-pack, solenoid or pan-magnet explanation does not fit them all; the cause depends on the unit/RPO and calibration and on whether the fault is hydraulic, electrical or mechanical.
Common Symptoms
- Transmission slips
- Hard or harsh shifting
- No overdrive
- Check engine light with shift or torque-converter clutch codes
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. Confirm the unit/RPO, the failed component, calibration, part number and VIN fitment before buying a solenoid, valve body, clutch kit, accumulator, magnet or transmission.

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.
