P0975: Shift Solenoid B Control Circuit Range/Performance
What to do
Note which gears still work. If more than one solenoid is reported, that pairing usually has a single cause.
What this code means
The control circuit for shift solenoid B is responding outside its expected window. Read alongside P0972: control circuit faults on two solenoids together are far more often one shared cause — a common supply, a shared connector, or a failed driver stage — than two independent failures.
Likely causes
Start here
- High resistance in solenoid wiring · moderate
- Failed shift solenoid · moderate
- Corroded transmission connector · moderate
Less common
- Control module driver failure · specialist

Information, not instruction
CarGeek is a reference, not a service manual. Its pages are written from public sources and from what other people have found, never from a manufacturer's own service information, so they can be wrong or incomplete for your particular vehicle. Some of what they describe carries real risk: high voltage, fuel under pressure, stored energy, hot and moving parts.
Have anything you intend to act on checked by a trained person against the manufacturer's own procedure for your vehicle. Nothing here replaces that procedure.

What makes one worth reading:
- The car — make, model, year and engine. The same fault behaves differently on each.
- What you measured, not only what you replaced.
- What actually fixed it — or that nothing did, which is worth knowing too.
