Cummins 6BT to a Chevy 4L80E / 700R4 / 4L60E / TH400 transmission, billet aluminum transmission adapter and billet steel flexplate. Late 2003 Up Common Rail Cummins .
This adapter uses a 6 liter Ford Power Stroke starter. If your Cummins engine has a standard transmission flywheel now your flywheel bolts will be too long for the new automatic transmission flexplate. You will need new shorter flexplate bolts.
Look at the top of Twinkie truck adapter on the left. This Junk has got to have a 20 degree tilt on the transmission or engine. This is what you don’t want.
