Hit Counter

Pricing: items are more expensive if purchased separately,  Packages offer substantial additional savings. Note: When comparing our pricing with others, make sure you are including the same parts, and are comparing the bottom line. We do not think we will be beat often, both in service and price

Customer Service: When you buy a package from High Impact, free tech support is available from a QUALIFIED engineer for any questions or issues you may have both during and after your install. An engineer will go over the details of your system with you at the time of purchase to go over options, and  verify the exact engineering and parts included in your kit is correct for your application

 

Note: We have dropped this package from our catalog: These transmissions are no longer manufactured by New Process, and we can no longer get these transmissions at the good price we were getting them for before. Sorry.

FYI: Current pricing on this trans:

New - out of production, no longer available.

Reman $3260 plus $1000 core charge

 

 

 

Stick trans replacement: All of the major components needed are supplied for this conversion

Automatic trans replacement: All of the major components are supplied for this conversion, with these exceptions:  

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.

Auto trans applications will also require replacement of the transfer case input shaft with a larger 29 spline part, or upgrade of the transfer case. We can work up a package to accomplish this.

Clutch Pedal assembly

(conversions from automatic) 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.

4WD

The (Brand New)  NV5600 transmission can be supplied in 4WD configuration, for use with Dodge style transfer cases 1993 and up. Adapters for other transfer cases are available, contact High Impact

2WD

The (Brand New) NV5600 are standard supplied with a fixed output yoke, and are equipped for Dodge electronic speedo drive. 

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

Crossmember

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

Automatic conversions: 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.

Lubrication

This transmission requires specific additives in its oil. The oil is available from Dodge. There is also a Pennzoil Part number 3501 that our New Venture supplier supports. If you are purchasing the trans from us, we can supply oil with the unit, since the trans is shipped truck freight. We cannot sell oil separately as it cannot be shipped UPS.

 

Manufacturer's specs indicate it holds 5 qts, however we recommend putting in 6 qts. There has been a problem with rear mainshaft bearing failure due to inadequate lubrication. Adding the extra oils resolves this problem.
