Hello friends. Have a Honda Pilot 2004.
Check engine code came after alternator failed. P0748 Pressure Control Solenoid A Electrical.
Soon only Only gear 1 and R work.
Transmission fluid was smelly, medium dark, also low.Changed Pressure Solenoids AB and C. Changed transmission fluid. Issue remains.
