P0972: Shift Solenoid A Control Circuit Range/Performance
What to do
Note exactly which gears still work — that pattern identifies the failed solenoid faster than a scan tool will. Then ask whether a hydraulic fault for the same solenoid is also stored, since that decides between a wiring repair and a valve body one.
What this code means
The module's control circuit for shift solenoid A is responding outside its expected window. The same division applies as for the pressure control solenoids: this code is about the drive circuit, while P0750 and P0751 are about whether the solenoid did its hydraulic job.
For shift solenoids there is an extra piece of information available at no cost, and it is the one from P0750 worth repeating here because it works just as well: which gears still function identifies which solenoid failed. The module runs solenoids in combinations, so one out of action removes a specific set of gears and leaves a specific set working. An owner can gather that on the drive to the garage.

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.
