GM S-Series Pick-ups and SUV's 1994-1999 Repair Guide

Transfer Case

Print

There are a number of different transfer cases used on these models. The New Process 231, New Venture Gear NV231, New Process 233 and the New Venture Gear NV233 transfer cases are used on models with part time four wheel drive. The Borg-Warner 4472 transfer case is used on models with full time four wheel drive.

All transfer cases covered in this guide are equipped with an identification tag which is attached to the rear half of the case; the tag gives the model number, the low range reduction ratio and the assembly part number. If for some reason it becomes dislodged or removed, reattach it with an adhesive sealant.
