At Extreme Transmission, we maintain one of the largest inventories of rebuilt transmissions in the city, with over 100 units on the shelf and ready for installation. This means there’s a very good chance we already have the transmission you’re looking for, helping you get back on the road faster.

Every transmission is built in-house by our experienced team. We understand that many transmission models come with known factory weaknesses, which is why we incorporate proven aftermarket upgrades to address these issues and improve reliability. For example, with the Dodge 68RFE transmission, we offer three different build levels based on your specific needs, including horsepower, towing requirements, and overall vehicle use. We tailor each build to match your application and performance goals.

We also stock a wide selection of GM 6L80 and 6L90 transmissions, including various computer calibration numbers. Our team will ensure the transmission you purchase matches your vehicle’s specifications, eliminating the need for additional programming whenever possible.

All of our transmissions can be professionally installed at our shop, or you can choose to install the unit yourself. For customer-installed transmissions, we simply require the vehicle to be brought in for a complimentary inspection so we can activate and validate the warranty coverage.

If you own a hot rod, classic car, or muscle car, we have plenty of options for you as well. We carry a variety of overdrive transmission solutions, many of which are in stock and ready to go, helping you improve drivability, fuel economy, and overall performance.

No matter what you drive, Extreme Transmission has the inventory, expertise, and custom-built solutions to keep your vehicle performing at its best.
