G Force GF-A-S 1989-02 Cummins to Allison Trans Adapter/Flexplate

The G Force Cummins to Allison adapter plate and flexplate kit accommodates 1989 thru 2002 Cummins 6BT engines, bolting to an GM Allison 1000 automatic transmission, model years 2001 thru 2007, or with the LT Duramax bellhousing pattern. The G Force adapters position the transmission straight, not angle rotated as some OEM applications.

Additional Information: The Cummins to Allison 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. An installation sheet detailing the modifications are included with purchase.
