246 Transfer Case Wiring Diagram

The 246 transfer case is a chain-driven unit that provides four-wheel drive capability to GMC and Chevrolet trucks and SUVs. It was introduced in 1987, replacing the older NP205 gear-driven unit. The 246 TC uses a cast aluminum case and housing with a six-bolt pattern on the rear face.

Inside the case is a planetary gearset that drives the front and rear output shafts. A chain runs from the input shaft to the sun gear of the planetary gearset. The 246 TC has an electronic shift control module (ESCM) that controls shifting between two-wheel drive (2WD) and four-wheel drive (4WD).

The ESCM is located on the side of the transfer case next to the shift motor. It receives inputs from various sensors, including: vehicle speed sensor, park/neutral position switch, transmission range sensor, 4×4 mode switch, and brake pedal position switch. Based on these inputs, the ESCM determines when to engage or disengage 4WD.
