Beginning at the start of production for the 2000 model year, General Motors introduced two new Allison automatic transmissions referred to as the 1000 Series and the 2000 Series, for light duty (8600-19850 GVW) and medium duty (19850-3000 GVW) commercial trucks. The 1000 and 2000 Series transmissions both have helical cut planetary gear systems to minimize noise concerns and come in two different gear ratio configurations. The 1000 Series uses closer steps to improve the shift quality that we now expect from an automatic transmission. The 2000 Series uses wider steps to accommodate the greater vehicle weights associated with the 2000 Series. The gear ratios for both of the new units are shown in this Manual. The 1000 and 2000 Series transmissions have a Park position, Reverse, Neutral and five forward speeds with 5th gear being overdrive, and are completely electronic shift controlled. Notice that the standard General Motors case connector has been utilized, and the Park/Neutral switch is exactly the same switch used currently on the THM 4L60-E transmission. Two different bottom pan configurations are also provided to make these units even more versatile. The 1000 and 2000 Series transmissions utilize five clutch packs (No Bands-No Freewheels) to obtain the five forward gears and reverse. This manual will cover the dis-assembly, rebuild of all components and re-assembly of both the 1000 and 2000 Series units.
