7A1-2 MANUAL TRANSMISSION (4WD)
GENERAL DESCRIPTION
There are two types of the manual transmission for full-time 4WD vehicles depending on the mounting location
of the AXC (Axial Plunger Pump Coupling). One type is a built-in type which the AXC is built in transfer case, and
the other type is an external type which the AXC is installed between the front differential and the front propeller
shaft. The AXC acts to automatically distribute the optimum drive force to the front and rear wheels while driving.
In addition, the built-in type AXC has two particular functions. The auto lock-up mechanism activates to automati-
cally render both the front and rear wheels in a rigid condition when a specified transfer torque is achieved. The
automatic torque variable mechanism automatically switches the torque to be generated among two different steps
in response to changes in vehicle speed.
PRECAUTION FOR TOWING FULL-TIME 4WD VEHICLE
When towing full-time 4WD vehicle, be sure to use the method described in SECTION 0A1.
