Design Features & Benefits
Designed for use with diesel engines up to 235 nhp. Four forward ranges and one reverse.
Clutches are multidisc design, oil-cooled, hydraulically-operated and self-compensating for normal wear. Spur-type planetary gears
are designed for strength, quietness and long life.
Automatic upshifting and downshifting within each drive range. Built-in inhibitors prevent downshifts or shifts into reverse unless
vehicle speed is within an acceptable range.
The Allison three-element torque converter provides smooth, shock-free operation. A choice of converters permits matching the
transmission to a wide variety of engines.
Converter-driven power takeoff drive on right side of transmission (as viewed from the rear) is standard on non-retarder models.
Design is SAE 6-bolt.
Provisions for neutral start switch, reverse signal switch, SAE regular-duty thread-type speedometer drive, electronic speedometer
drive and parking brake.
