The Borg-Warner 44-06 instruction shift and electronic shift transfer cases are a three-piece magnesium design. 
The unit transfers engine power from the transmission to the front and rear axles. Under normal driving 
conditions the unit is in 2-wheel drive high (2H), but when desired, the operator may shift into 4-wheel drive 
high (4H) or 4-wheel drive low (4L). The operator may shift from 2H to 4H or from 4H to 2H at any speed up 
to 88 km/h (55 MPH). The vehicle speed must be less than 5 km/h (3 MPH), the brake applied, and the 
transmission in NEUTRAL to shift into 4L. The transfer case is shifted either manually or electronically. The 
unit is lubricated by a positive displacement fluid pump that channels fluid flow through holes in the rear output 
shaft. 

TRANSFER CASE - POWER FLOW 

In the neutral position, no power is transmitted to the front or rear drivetrain.

When the driver selects 2H, the (A) reduction hub is in the forward position and puts the transfer case into 
direct drive. The (B) input shaft and (C) rear output shaft are locked together. The (D) 4-wheel drive lockup hub 
is in the forward position disengaging the front driveline.
