The P0750 code in your 2010 Chrysler Town & Country indicates a malfunction in the Shift Solenoid A circuit. This solenoid is part of the transmission solenoid pack that controls gear engagement in the 6-speed automatic transmission. Symptoms typically include harsh or delayed shifts, stuck in one gear, or transmission failsafe mode.
Understanding Solenoid Pack Function
The 2010 Town & Country uses the 62TE 6-speed automatic transmission with an internal solenoid pack containing multiple shift and pressure control solenoids. Solenoid A controls specific gear engagements, and when it fails, the transmission can't properly execute certain shifts. P0750 can indicate electrical failure, mechanical sticking, or hydraulic flow problems affecting that solenoid.
Common Causes
Electrical failure within the solenoid is most common—the internal coil may open or short. Contaminated transmission fluid causes solenoids to stick. Wiring or connector issues between the TCM and solenoid pack create circuit problems. The solenoid itself may be mechanically stuck open or closed. Low transmission fluid level affects solenoid operation and can trigger codes.
Diagnostic Process
Check transmission fluid level and condition first—low or dirty fluid affects solenoid operation. Retrieve freeze frame data to understand conditions when the code set. Test solenoid resistance with the transmission pan removed if accessible. Check wiring continuity between TCM and solenoid connector. Monitor solenoid operation with a scan tool capable of bidirectional control. Some shops can test individual solenoid flow rates.
Repair Solutions
If a single solenoid has failed, the entire solenoid pack is typically replaced—individual solenoids aren't usually sold separately. The solenoid pack is accessible by dropping the transmission pan. When replacing the solenoid pack, also replace the filter and fluid. If the problem is wiring-related, repair connections without replacing the pack. A quality remanufactured solenoid pack can save money over OEM pricing.
