If your automatic transmission is showing symptoms related to torque converter engagement—such as harsh shifts, slipping at cruising speeds, or transmission fault codes—the TCC solenoid is a commonly serviced component. Dorman designed this unit to meet the same mounting, electrical interface, and fluid-flow characteristics as the factory part for the specified years and models, offering a cost-effective repair without modifying the transmission or wiring harness.
This solenoid is manufactured to match the original equipment for a range of Chrysler, Dodge, Ram and Volkswagen platforms across several model years. Always confirm compatibility by entering your vehicle into the garage fitment tool and checking the Confirmed Fit bar before ordering.
Dorman engineers the 926-378 to replicate the factory solenoid's key dimensions and electrical connections so it installs without modification. The unit undergoes testing to ensure it controls hydraulic pressure and torque-converter lockup in line with original performance expectations.
A failing TCC solenoid can trigger warning lights, cause rough cruising, or produce diagnostic trouble codes related to torque converter operation. Replacing a worn or faulty solenoid is a standard repair to restore smooth lockup and improve shifting behavior, when those symptoms point to the solenoid rather than the control module or valve body.
Installation is typically a direct swap at the transmission solenoid pack or valve body area and requires standard hand tools and safe jacking/support of the vehicle. Depending on the vehicle, you may need to drain some transmission fluid and clear related fault codes after replacement.
Who is this for: This Dorman 926-378 solenoid is intended for DIY mechanics, independent shops, and fleet technicians who need a reliable, direct-fit replacement for specified Chrysler, Dodge, Ram and VW models. It’s well suited for owners troubleshooting TCC-related symptoms where wiring and electronic controls have been checked, and for anyone seeking a quality aftermarket option backed by experienced product support.
Q: Will this solenoid fix transmission slipping?
A: If diagnostics point to a faulty TCC solenoid and the control module and wiring are good, replacing this solenoid can correct slipping related to torque-converter lockup.
Q: Do I need to change transmission fluid when replacing the solenoid?
A: You may lose some fluid during installation; a partial fluid top-up or filter service is recommended depending on vehicle service history.
