For all the technical service information you could need for the Allison tranny, grab a copy of Allison 1000 / 2000 Transmission Rebuild Repair Manual. It’s another gem from the experts at Automatic Transmission Service Group.
The Allison 1000 / 2000 was one of the first trans to come out of General Motors at the beginning of the 21st century. The 1000 and 2000 trannys were introduced with helical cut planetary gear systems and two unique gear ratio configurations. The 1000 utilized the kind of shift quality that’s become de facto in automatic transmissions. With the greater weight associated with the 2000 series, the 2000 trans has wider steps. Designed for light duty and medium duty commercial trucks, GM made these trannys a go-to for many of their popular vehicles. And engineers at GM worked closely with the team at ATSG, making sure every exploded view and every word was manufacturer-approved and beneficial.
The Motor Bookstore is a big fan of the ATSG repair and rebuild transmission manuals. Reading through their publications, we’ve come to appreciate the delicate touch that goes into managing transmissions. We believe, regardless of level of experience, anyone that does manage these trannys would put themselves in a good place having a copy of Allison 1000 / 2000 Transmission Rebuild Repair Manual nearby. It provides the info needed to quickly get through bolt identification, line pressure tests and various disassemblies. And while this material was definitely designed for the trained tech, we’d dare think we could perform these operations ourselves.
