These trucks when ordered with a 5 speed, typically came with an NV4500 trans. Thus, the above system is designed to replace an automatic transmission with an NV4500 5 speed. If you need a kit to upgrade a stick trans, contact us, we’ll work up a kit!.

Automatic trans replacement: All of the major components are supplied for this conversion, with the exception of the clutch pedal assembly. If desired we can source these parts from a dealer, however most likely at a higher cost than you can buy them direct from the dealer.

Clutch Pedal assembly

These parts are available from the dealer. 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.


The NV4500 transmission can be supplied in 4WD configuration, for use with GM style transfer cases 1986 and up. Adapters for other transfer cases are available, contact High Impact


The NV4500 are standard supplied with a fixed output yoke, and are equipped for GM electronic speedo drive. These transmissions can also be supplied with a slip-yoke rear output, and Dodge type mechanical speedo provisions if desired

Drive Shafts

You will need to have your driveshafts modified for length. A local driveshaft shop is usually available to do this. If necessary, we can do it, however it is better to install the unit FIRST, then measure and build/modify driveshafts


You may need to relocate your crossmember, this can usually be done by re-drilling the frame and bolting into the desired location. You will need to drill the crossmember for the bolts to the larger NV4500 transmission mount

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.
