Installation & Application Notes: 

NV4500 Replacing an Automatic Transmission:

The package above forms a system is designed to replace an automatic transmission Behind a Cummins Diesel. All of the major components needed are supplied for this conversion, with the exception of the clutch pedal assembly.

Clutch Pedal assembly

These parts are available from the dealer, or if you prefer, a junkyard. You will want the stock bracket, pedals and linkage components from your same-year stick-equipped vehicle. The master cylinder we supply will fit this assembly. If desired for convenience, we can attempt to source these parts from a dealer, however most likely at a higher cost than you can buy them direct from the dealer.

4WD applications

Dodge Cummins Trucks with auto transmissions: were supplied with a 23 spline input on the transfer case. All of the Factory Dodge Cummins 5 speed applications were 29 spline into the transfer case. The 29 spline shaft is stronger than the 23 spl shaft, and the auto trans with the torque converter does tend to cushion the output of the trans from the heavy torque pulses generated by the Cummins diesel.

NP241 or 271: All we would need to change is the input gear – $155.

Drive Shaft(s) You may need to have your driveshaft(s) modified for length. A local driveshaft shop is usually available to do this.

Stick Shift

It will be necessary to cut a hole in your floorboard to accommodate the stick shift. A simple boot can be mounted over the hole to dress this.

Computer

You will need to have your computer reflashed or replaced to accept a 5 speed. Sometimes nothing needs to be done to computer it just automatically adjusts.

2WD

The NV4500 are standardly supplied with a Dodge style slip yoke, and provisions for a choice of mechanical or electrical speedo, as needed for your application.
