Electrical systems and electronics have made today’s vehicles more refined and more durable, and infinitely more complex. Transmissions have benefited from this electrical revolution.

When the time comes to repair these systems, Transtar has the parts you need to do the job right, the first time, every time. Whether you are looking for a harness repair kit, a replacement solenoid, or the complete valve body with all the solenoids and sensors installed, Transtar has you covered.
Electrical Transmission Parts
All electrical items sold by Transtar meet or exceed the O.E. fit, form and function. When an OE part is not available Transtar works to develop a solution.

Whether you need a rebuild kit for a solenoid or a connector repair kit, Transtar offers solutions that allow the repair to be made and the vehicle to be restored to the original factory standards.

Berkeley Standard

Berkeley Standard remanufactures a variety of electronic control modules for a wide range of transmissions made by American, European, Japanese, and Korean OEMs. Our remanufacturing process restores both hardware and software of the module to 100% OE specification. Each module is disassembled, cleaned, inspected, and tested down to the smallest component level, and any part that does not meet OE specs are 100% replaced. Modules are unlocked, virginized, and made ready for programming or SCN coding..  Learn More



Remanufacturing is a complex process to take an existing part and rebuild it so it performs like new. In partnership with Dorman Products, Transtar offers thoroughly re-manufactured TEHCM replacements for more than 26 million vehicles on the road.  Learn More
