NP246 Vehicle Speed Sensor

The vehicle speed sensor, the VSS, is used in the New Process Gear Transfer Case NP-246. Depending on year and vehicle model it can use two or three. There are two types of the VSS. A push in model or a screw in model like the one pictured below.

To be on the safe side, it is good practice to replace these sensors when rebuilding the transfer case. The Np246 is primarily used in GM vehicles like the Suburban, Avalanche, Escalade, Tahoe and Yukon.
