Pre-2002 Cummins Engine Adapter to GM Allison 1000

Description

This pre 2002 Cummins engine adapter to GM Allison 1000 transmission adapter from G Force Performance Products is precision CNC-machined out of 6061 Aluminum with 4140 alloy steel flexplate.   This adapter kit allows the pre-2002 Cummins B series engines to bolt to the  GM Allison 1000 series automatic transmissions found in the 2001 thru 2007,  GM trucks  with the Duramax bellhousing pattern.  A stand alone transmission controller is required.

This adapter kit requires the use of a Ford 6.4L or 6.0L Powerstroke starter.  Some bellhousings will require additional interior clearance for the starter snout.  In addition some clearance modifications to the engine block pan rail on the passengers side as well as grinding of the starter mounting flange may be necessary.
