Rebuild your Allison 1000- or 2000-series transmission with this easy-to-follow book that features step-by-step procedures.
Introduced in 1999 by Allison and 2001 by General Motors, the Allison 1000- and 2000-series transmissions have become the most popular heavy-duty transmissions in production today. Used by multiple manufacturers, including GM, Freightliner, International, etc., millions are on roads around the world.
Automatic transmissions are often seen as mysterious and overly complicated, but much of the guesswork has been simplified to its basic elements in this easy-to-follow guide. This book covers the identification process, operation, diagnostic pointers, common failures, and repair and rebuild procedures for the 1000- and 2000-series transmissions. Upgrades to make the 1000 more robust for performance applications are covered as well as the companies that offer upgrades.
This detailed instructional manual is authored by Steve Garrett, a service engineer and instructor for General Motors and a member of the Automatic Transmission Rebuilders Association (ATRA). Quality photos of the rebuild process are featured along with torque specifications and identification of all major and most minor components. If you are looking at performing a rebuild project on your own or you just want to know how your Allison works, this is the book for you.

Bellhousing cracks are common on Allison application, so inspect for them.
The IMS must be properly positioned with the shift shaft, rooster comb, and parking-pawl linkage. The retaining bolt and dowel pin are then installed. If removing the IMS for any reason, it is always a good practice to replace the shift-shaft seal.
Inspect the planetary gears and thrust washers for damage and wear. If the washers or planetary show wear, make sure to fully inspect for lubrication circuit restrictions and leakage as well as the transmission fluid cooler for restrictions. Tooth damage is generally due to bearing failure somewhere in the unit and pieces of the bearing migrating back into the gears, which result in damage.
Multiple versions of the 1000- and 2000-series units were used, such as this Allison 2400. Make sure to find out which transmission you are working on. This information is located on the tag. The service process is the same for all versions, but the parts vary greatly and many are not interchangeable.
Remove the detent spring and the 15 highlighted bolts, wiring harness, and any pipes that may interfere with removal of the valve body.
Install the gasket followed by the adapter/extension housing. Carefully shift the housing to align the bearings, park pawl pin, and, on 2WD applications, the speed-sensor tone wheel. Make sure the housing is fully installed against the case and the gasket.
Used with the late-model 6-speed applications, the 2010–2019 valve body uses seven solenoids. They are housed in the valve body. The pressure-control solenoid is a true PCS- design solenoid, providing variable line pressure control. The line pressure PCS was moved into the valve body and the auxiliary valve body was eliminated. No pipes are used.
