DRIVE TRAIN
Description
The drive train consists of the transmission/torque converter
assembly and two drive lines.
The transmission/torque converter is mounted on and driven
by the engine. The torque converter assembly provides for
mounting and driving the two section main and single section
hydraulic pumps. The transmission is a Range Shift with six
forward speeds and six reverse speeds. The transmission is
controlled electrically by a shift lever/knob located on the
right side of the steering column and an axle drive mode
selector rocker switch located on the left side of the front
console.
The transmission/torque converter oil is cooled by passing
the oil through an externally mounted transmission cooler.
