Cummins to Chevy / GM Transmissions

We offer transmission adapters for the following Chevrolet and GMC Transmissions:
TH350, TH400, 700R4, 4L60E**, 4L80E, Chevy Allison 1000 5&6 speed automatics

**Some 4L60E Transmissions use a 300mm torque converter.  If your 4L60E transmission has a bolt hole at the top of the "tent" of the bell housing you have a transmission that will require the 300mm flex plate option that we offer.**

The adapters use the 2003-2007 6.0L Ford Power Stroke Starter.  All adapters work with a stock dimensioned torque converter, so using your existing torque converter is possible, although we recommend using a OEM diesel converter at least for satisfactory performance.

We do not currently make adapter kits for Chevy manual transmission applications.  Due to the small clutch that would be required, we recommend upgrading to a Dodge or Ford 5-speed.  If you already have a Chevy 5- speed, it can be converted to bolt to a Dodge bell housing.
