EIS strives to provide our customers with the greatest quality products and service!

Why a Custom Transmission Build?

At EIS we build towards application! With that said, each custom build is different. A custom-built transmission can be for performance or overall longevity. Customers often want custom tow transmissions, which include customers towing travel trailers, boats, horse trailers, and work trailers etc. This towing often takes a toll on a stock transmission, which is why EIS strives to provide the best quality custom builds and packages for each customers unique needs!

Custom Transmission Builds

With each EIS custom transmission build comes trust and quality service! We know at EIS that custom transmissions are a huge expense. For this reason, we strive to work with each customer on their exact needs. With each custom transmission build EIS is looking to reach peek towing ability as well as peek performance. Once EIS has completed a custom transmission build our team then custom tunes the new transmission to the truck’s engine. This process is one that cannot be missed when upgrading and building a custom transmission. With each custom package EIS works with customers to determine if any other engine components need to be upgraded along with the custom transmission. At EIS we’ve allied ourselves with the most cutting-edge parts manufacturers and stay up on the latest training and transmission service techniques with continuing education!
