If you are converting from a standard transmission you will need to source an automatic steering column from a salvage yard. While ATS offers rebuilt versions of these transmissions using heavy duty upgraded parts, the upgraded heavy-duty transmissions still do not offer all of the benefits of a fully built Allison 6-speed automatic.

• 1994-1995 Ram 2500/3500 5.9L came with the 47-RH 4-speed automatic transmission
• 1996-2002 Ram 2500/3500 5.9L came with the 47-RE 4-speed automatic transmission

The information in this guide will explain the different combinations of Allison 5-speed and 6-speed cores that can be used when upgrading to the ATS Allison conversion kit. We have designed the ATS conversion kit to be able to use any GM Allison 5-speed or 6-speed unit manufactured from 2001 to 2019 that came out of a 2500 or 3500 GM Truck. There are 4 basic configurations of the Allison LCT-1000 transmission. Each one of these transmissions use a different pump, Pressure regulator system and Valve Body configuration. These three parts can not be interchanged without causing severe problems. The different ATS conversion kit options are designed around the transmission core you are starting with. Each kit is designed to be sure the kit you order is shipped with the exact parts you need when you rebuild and up-grade your transmission to be used in the ATS conversion package.

2001 to 2005, 5-Speed Allison LCT-1000. When starting with this core type transmission you must install the ATS modified valve body with internal harness, Manual linkage shaft and Internal mode switch.

2006 to 2010, 6-Speed Allison LCT-1000, When starting with this core type transmission you can use all of the original components. The factory 06-10 VB is hydraulicly limited because of the design of the trim valves, this design limits the line pressure that is allowed to apply the clutch packs which reduces the transmissions ability to hold power. If your Cummins power level is anything above stock it is highly recommended to upgrade to our Valve Body. The ATS valve body is new and designed to provide full line pressure to the clutch packs of the transmission and ensures the transmission will hold increased power levels.

2011 to 2016, 6-Speed Allison LCT-1000, When starting with this core type transmission you can use all of the original components except for the output shaft. The factory output shaft is the wrong spline count to adapt to the Dodge/Ram transfer case. You will need to replace the output shaft with a stock 2001 to 2010 shaft or ATS billet output shaft when doing your rebuild.

2017 to 2019, 6-Speed Allison LCT-1000, When starting with this core type transmission you must change out the pump/stator support assembly and input shaft to the 2011 to 2016 version. The factory output shaft is the wrong spline count to adapt to the Dodge/Ram transfer case. You will need to replace the output shaft with a stock 2001 to 2010 shaft or ATS billet output shaft when doing your rebuild.
