P0750 on Volvo
Shift Solenoid A Malfunction
P0750 on Volvo vehicles indicates shift solenoid a malfunction. Au7o has documented this code across 3 Volvo models — most commonly on C70, S70, V70. 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 Volvo range from $400 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 Volvo by Model
Volvo C70(1 issue)
- Automatic Transmission Solenoid Failure2006-2013
The Aisin-Warner automatic transmission develops harsh shifting and delayed engagement due to worn solenoids in the valve body. The transmission fluid change interval is often exceeded, accelerating wear.
Volvo S70(1 issue)
- AW50-42 Automatic Transmission Failure1998-2000
Like the 850, the S70 shares the Aisin-Warner AW50-42 automatic transmission that develops internal failures. The valve body, solenoids, and torque converter are common failure points, especially in turbocharged models.
Volvo V70(1 issue)
- AW55-50/AW55-51 Automatic Transmission Solenoid Failure1998-2007
The Aisin-Warner AW55-50 and AW55-51 automatic transmissions used in V70 models are known for solenoid failures, particularly the SL1 and SL2 linear solenoids that control shift pressure. Failed solenoids cause harsh or delayed shifts, transmission slipping, and limp mode engagement. The solenoids deteriorate due to ATF contamination and heat, especially when fluid changes are neglected.

What does P0750 mean on Volvo?▼
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 Volvo specifically, this code is documented across 3 models.
