This pre 2002 Cummins engine adapter to GM transmission bellhousing adapter flexplate will allow you to bolt your 2002 and earlier Cummins B series engines including a 4BT to a GM automatic transmission. These transmission include TH400, 700R4, 4L80E. Our adapter is precision CNC machined out of 6061 Aluminum with a 4140 alloy steel flexplate.
This adapters position the transmission straight, not angle rotated as some bread truck adapters. 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. Installation instruction will be included with the adapter and can also be seen in our videos on the Jonesy’s Auto Club YouTube channel. Hardware kits are available separately.
(This item will not work on some 4L60E transmission with removable bellhousings)
