OPERATION

OPERATING RANGE


Transfer case operating ranges are:

- 2H (2-wheel drive).
- 4H (4-wheel drive).
- 4LO (4-wheel drive low range.

The 2H range is for use on any road surface at any time.


The 4H and 4LO ranges are for off road use only. They are not for use on hard surface roads. The only exception being when the road surface is covered by ice and snow.


The low range reduction gear system is operative in 4LO range only. This range is for extra pulling power in off road situations. Low range reduction ratio is 2.72:1.


SHIFT MECHANISM


The transfer case is operated by an adjustable floor mounted shift linkage. The transfer case shift lever is directly attached to the shift sector. The sector operates the range and mode forks within the transfer case.


A straight line shift pattern is used with a NEUTRAL detent. Lever range positions are imprinted in the shift knob.


SHIFTING


The transfer case can be shifted between the 2H and 4H operating ranges while the vehicle is in motion. The vehicle must have the transmission placed in NEUTRAL, or the clutch depressed in the case of a manual transmission, and be moving less than 2-3 MPH when shifting into and out of the 4L operating range.
