P0750 — Shift Solenoid A Malfunction

Severity: Warning Can you drive? With caution: limp mode possible, have it checked soon Make: All makes (OBD-II standard)
MeaningThe transmission control module has detected an electrical issue with the primary shift solenoid valve, which controls fluid flow to engage specific gears. When this circuit fails, the transmission cannot shift properly between gears as commanded.
FamilyPowertrain (P)

Typical symptoms

The transmission gets stuck in a single gear, usually second or third (limp mode)
Harsh or delayed shifting when moving the gear selector
Check Engine light is illuminated on the dashboard

Common causes

Internal electrical failure within the shift solenoid itself
Corrosion, damage, or loose pins in the transmission wiring harness connector
Low transmission fluid level or severely contaminated fluid affecting valve movement
Internal failure inside the transmission control module

What to do

Have a technician check the external wiring and connector to the transmission first, as these are exposed to road debris and moisture. You should address this soon to prevent internal wear inside the transmission from driving in a limited gear.
