Re: Shift Solenoid A engine code
If the transmission is shifting normally, you could first try to reset the fault and see if it comes back. The shift solenoid is part of the solenoid block inside the tranny.
If the fault comes back or there are shifting issues, you could first try to clean the big connector on the tranny. If that doesn´t help, you most probably have to change the solenoid assy. If you have reasonable mechanics skills, you could do this change yourself, no rocket science.
