E40D & 4R100 Transmissions

Custom tuned. Forged parts. Built specifically for you.

Brian's Truck Shop began building transmissions in 1990. The engine performance was always there, but the Ford factory transmissions were not. We have spent years learning and developing transmission modifications that meet the needs of an ever-growing performance market.

Transmissions are built to order and customized by horsepower, tire size, and performance goals for your truck. Whether you have a Ford Lightning you race regularly, a Powerstroke dually that you pull your trailer with, or your wife's daily driver, our BTS transmission is suited for all conditions.

Come see us & have your transmission installed at our shop or ship the built transmission to you!

Our Transmission Fluid Provider:

High Performance Lubricants is not your typical oil company. When making a lubricant it’s all about choices. Although there are only a few base oil suppliers and only slightly more additive suppliers to choose from there are various quality levels of products available. High Performance Lubricants chooses the best base oils combined with the highest quality additives for our products. The end result is a significant improvement in our oils life and wear reduction compared to others. These differences can easily be verified by oil analysis.
