Dodge Ram Six-Speed Upgrade

Q. We have a 2000 Dodge 2500 Ram truck with a Cummins diesel engine and a five-speed manual transmission. We’d like to update it to the new six-speed transmission. Do you have any information on this swap?

— R.S., Dallas, Texas

A. A six-speed conversion was described in The Turbo Diesel Register (TDR) magazine. A member performed a swap to a six-speed manual transmission (NV5600) and gave a brief write-up in issue 33, page 42.

The shop that did the work was Performance Transmission in Angleton, Texas; (979) 864-3280.

TDR is an excellent resource for owners of Dodge trucks with Cummins engines and can be reached at (770) 844-1600, turbodieselregister.com — K.F.
