NV3550 Conversion
Package Pricing below
The NV3550 is an excellent option to consider in smallblock Ford V8 (289-302-351 Windsor series motors) Jeep applications. It will comfortably handle a mild V8 in a vehicle such a as a Jeep, and will fit under the body in a Jeep with very few additional modifications.
NV4500 Conversion
There is one other popular replacement option for these Jeeps: The NV4500. This trans is way-oversize for the application, and requires a body lift or extensive floor pan modification to fit. The usual incentive for this conversion is to get the truck style wide ratio, almost granny 1st gear which can be useful for offroad use. On the other hand, this conversion will make a your jeep drive more like a truck. If this looks like the option or you, High impact does have available a package using the NV4500.

Adapting To The Transfer Case
NP231 – This is the transfer case found stock in Jeeps from 1989 – 2000, and most jeeps (except Rubicon) from 200-up. Some 87-88 Jeeps will have the 231. Units that came with the 2.5L 4 cyl engine, and units that came behind the Peugeot 5spd (1987-88) will have 21 spline input gears. If you wish to retain this transfer case, you will need to replace the input gear with a 23 spline part (Listed below). The remainder of the NP231 Tcases came with a 23 spline input, and will bolt up directly to a NV3550 transmission
Atlas II Transfer Case – This case is available in configurations for direct bolt up.
