P0753 Isuzu Code - 1-2 Shift Solenoid Fault
Quick Answer
1-2 Shift solenoid valve is turned ON or OFF by the Transmission Control Module (TCM) in response to signals sent from the park/neutral position (PNP) switch, vehicle speed and Engine Control Module (ECM) (throttle opening). Common causes include Low transmission fluid level, Dirty transmission fluid, Faulty shift solenoid valve. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.
