Description

Tremec TR4050 Cummins 6BT adapter kit:

This adapter kit bolts the Cummins 4BT or Cummins 6BT to the Tremec TR4050 5 speed transmission.  The transmission is a major upgrade over the NV4500 as it shifts like a car, weighs 100 lbs less, and is rated at 600 ft/lbs at 15,000lbs.

The value of this Tremec TR4050 Cummins 6BT adapter kit is it bolts directly to the 1994 to 2007 Dodge flywheel housing; starter plate, from the Ram 2500 and 3500 pickup trucks.  The 1989 to 1993 flywheel housing will not work.

Our Tremec TR4050 Cummins 6BT Diesel Conversion kit uses the Dodge Starter and the 1994 Chevy 1 ton Clutch; Part #K70188-01HD, both off the shelf parts from AutoZone.  The clutch cover must be rounded on the edge, not the square edge style.  Compared to the Cummins 4bt bread van adapter plate that retains the factory bell housing this kit moves the starter to the drivers side for more exhaust clearance.  Recommend using both the master and slave combination from a 1999 Jeep Wrangler 4.0.  This has been proven to work with simply modifying the connection from master cylinder rod to clutch pedal and using  one washer approx .080″ thick top and bottom between the bell and slave.

This is not a complete installation kit but includes the everything needed to bolt the Tremec TR4050 to a Cummins 6BT turbo diesel engines.  Looking for the Cummins to Chevy SM465 adapter kit?  Click here.
