Shift solenoid A — malfunction
Where to start
Shift solenoid A is not responding. Solenoids live in the valve body and often stick because of dirty fluid rather than failing. First check the fluid level and condition and the transmission connector — it is on the outside and easy to reach.
A code is not a diagnosis. It says which check failed, not which part to replace. Clearing it without repair only means the car will report it again in a few trips.

How the app helps
CarScan reads this code from your car through an OBD-II adapter, shows whether it is active now or only stored, names the module that reported it, and puts it into a plain-text report for your mechanic.
