P0757: Shift solenoid B stuck on
Shift solenoid B in the automatic gearbox is stuck on, so it picks the wrong gears or stays in one. Dirt jamming the valve is common.

What P0757 means
Shift solenoids route fluid inside the automatic gearbox to move from one gear to the next. Exactly which job solenoid B does is up to each manufacturer. The control unit sees the valve still acting when it shouldn’t, as if it had jammed in the on position.
Most common causes
- Dirty gearbox fluid holding the valve in place
- Shift solenoid B mechanically jammed
- Control wire shorted to earth, keeping it switched on
- Dirty or worn valve body
- Transmission control unit (uncommon)
Symptoms
- Engine warning light on
- Gearbox selects the wrong gear
- Pulls away in a high gear with little power
- Stays in one fixed gear (limp mode)
Can you drive with P0757?
With care You can drive, but the gearbox often sticks in a single gear, so the car feels weak or over-revs. Drive calmly to a garage and avoid fast roads if it won’t change up.

How to check it
Note when it happens: cold or hot, when stopping or moving off. With a scanner, see if the code returns straight after clearing it: instantly usually means electrical, later on more likely mechanical.
How to read and clear P0757 with Final OBD
Plug an OBD2 scanner in under the steering wheel, switch the ignition on and open Final OBD. Under Faults you’ll see P0757 with its description and whether it’s confirmed, pending or permanent.
This code is usually stored by the gearbox control unit. If the car reports it over standard OBD, you read it for nothing with FREE; to read it straight from the gearbox control unit, with its description and clearing, you need PRO.
Clearing the code only turns the light off: if the cause is still there, it comes back. Clear it once it’s fixed, and not right before an inspection. It’s all in how to read and clear fault codes and in inspections and OBD.

How do you clear P0757?
With an OBD2 scanner and an app like Final OBD, which clears it for free if it’s stored by the engine control unit. But clearing it only turns the light off: if the cause isn’t fixed, P0757 comes back.
Read it on your car
Final OBD reads and clears engine faults through standard OBD for free, each one explained in plain English. With PRO it also reads the faults of every control unit, each make’s own codes included, and clears them in all of them.
