P0750 on Mazda
Shift Solenoid A Malfunction
P0750 on Mazda vehicles indicates shift solenoid a malfunction. Au7o has documented this code across 3 Mazda models — most commonly on 626, MPV, Tribute. This code indicates the transmission control system detected a malfunction in shift solenoid 'A', one of the electrically operated valves that direct hydraulic fluid to engage gears. The computer commands these solenoids to control upshifts and downshifts, and it monitors their circuits and the resulting gear changes. When solenoid A doesn't respond electrically as expected — or the resulting shift doesn't happen correctly — this code is set. You may notice harsh, delayed, or missing shifts, or the transmission may enter a fail-safe (limp) mode. Typical repair costs on Mazda range from $200 to $3,500, depending on the specific model and root cause.
Common Causes of P0750
- •Failed or stuck shift solenoid A
- •Open, shorted, or chafed solenoid wiring
- •Corroded or loose transmission connector
- •Low, dirty, or degraded transmission fluid
- •Clogged solenoid or valve body passages
- •Internal valve body or hydraulic fault
- •Faulty transmission control module (TCM)
P0750 on Mazda by Model
Mazda 626(1 issue)
- CD4E Automatic Transmission Failure1998-2002
The 1998-2002 626 uses the Ford CD4E automatic transmission, which is notorious for premature failure. The transmission develops harsh shifting, slipping, and complete failure typically between 60,000-100,000 miles. Internal servo bore wear, solenoid failures, and torque converter issues are common. This is the same problematic transmission used in the Ford Escape and Mercury Cougar of the same era.
Mazda MPV(1 issue)
- Automatic Transmission Slipping and Harsh Shifting2000-2006
The second-generation MPV's 5-speed automatic transmission (shared with Ford) develops slipping, harsh shifts, and delayed engagement between 80,000-120,000 miles. The torque converter lock-up clutch wears, and the valve body solenoids stick. The transmission fluid often shows signs of degradation (dark color, burnt smell) well before problems are felt. Towing or heavy passenger loads accelerate wear.
Mazda Tribute(1 issue)
- CD4E Transmission Failure2001-2008
Same CD4E automatic transmission as the Ford Escape, prone to premature failure. Internal clutch and servo bore wear. V6 models with CD4E are most affected.

What does P0750 mean on Mazda?▼
P0750 stands for "Shift Solenoid A Malfunction." This code indicates the transmission control system detected a malfunction in shift solenoid 'A', one of the electrically operated valves that direct hydraulic fluid to engage gears. The computer commands these solenoids to control upshifts and downshifts, and it monitors their circuits and the resulting gear changes. When solenoid A doesn't respond electrically as expected — or the resulting shift doesn't happen correctly — this code is set. You may notice harsh, delayed, or missing shifts, or the transmission may enter a fail-safe (limp) mode. On Mazda specifically, this code is documented across 3 models.
