Overview
This manual will, in detail, give the information you will need to convert a 4x4 1996-1999 Nissan Pathfinder from an automatic transmission to a manual transmission. Having a manual transmission in your Pathfinder gives you more control, lower gears, and more power than you would have with an automatic. Other benefits include better gas mileage, lower maintenance cost and reduced electronic dependence.
Although the part prices and part numbers are directly from the dealership many auto recyclers will have serviceable parts at a much lower price. It is highly recommended that you contact auto recyclers in your area for the manual transmission and transfer case assembly, or transmission only in the case of 2wd vehicles.
WARNING: perform these procedures only if you have advanced mechanical knowledge. Certain aspects such as the definition of common tools or how to use them will not be within the pages of this manual. Before attempting any of these procedures on your Pathfinder be aware that this is a labor intensive and time consuming operation; your vehicle will be out of commission for days if not weeks. Parts of this operation will require the assistance of a helper.
Model designation is for 4x4 1996-1999 models, but most of the instructions will cross over to 2wd and the later 1999.5- 2004 years
Notice: 2001 and later models require a different transmission than earlier models.
