2003-2024 Cummins to Allison | GF-A-SL

Fits Engine Years: 03-25. Fits Transmissions: Allison 1000 and 2000 Series. The G Force Cummins to Allison Adapter Plate and Flexplate Kit accommodates 2003-2025 Cummins 6BT / Common Rail engine, bolting to a GM Allison transmission, for model years 2001-2025, or with the Duramax bellhousing pattern. The G Force adapter positions the transmission straight, not angle rotated as some OEM applications. The Allison transmission adapter kit requires the use of a Ford 6.4L Powerstroke starter. As an option, a Ford 6.0L Powerstroke starter can be used, but some bellhousings will require additional interior clearance. In some applications clearance modifications to the engine block pan rail and the Powerstroke starter may be necessary.
