The Allison 1000 transmission is a fully automatic transmission often used in heavy-duty trucks and other commercial vehicles, particularly paired with Duramax diesel engines in GM trucks. An Allison 1000 transmission rebuild kit includes essential components to restore the transmission’s performance and durability. These kits typically contain friction and steel clutch plates, gaskets, seals, O-rings, bearings, bushings, and a filter, with some premium versions including upgraded torque converters and shift kits for improved durability and performance.

Features

Searching for a rebuilt and upgraded used Allison transmission. At All American Motors Hub, we provide top-quality used transmissions at affordable prices. We have the best solution to restore your ride if you want an Allison 1000 transmission. Among our best-selling products, we have The Allison 1000 transmission for sale, as we provide the best deals and discounts on all our products. We also offer high-quality used transmissions for different model years to keep your Cadillac STS running like new!

A used Cadillac STS Allison 1000 transmission fits vehicles that were originally factory-equipped with this unit in the correct calibration for the STS platform. Fitment depends on your specific model year and engine pairing, and the Allison unit in the STS is specifically calibrated for the vehicle’s transmission control module and torque converter specification. We complete a VIN verification before every order ships to confirm the correct unit for your specific Cadillac STS, ensuring the replacement is fully compatible with your vehicle’s driveline and electronic systems.

Given the Allison 1000’s commercial-grade construction, a proper rebuild involves specialized tooling and expertise that goes beyond a standard passenger car transmission shop. Quality Allison rebuild kits and the labor to install them correctly can make rebuild costs approach or exceed the cost of a quality used replacement. A used OEM Allison 1000 from a comparable-mileage donor vehicle gives you a factory-assembled unit at a known price that restores the smooth, effortless performance the STS was designed to provide — without the rebuild timeline or cost uncertainty.

Every used Cadillac STS Allison 1000 transmission we sell is backed by up to a 90-day warranty. Shipping runs 2 to 5 business days from purchase. Installation is not included, but our team can help you find a qualified Cadillac or Allison-experienced transmission shop in your area. These are genuine Allison OEM units and we take pride in the quality of every transmission we source.
