PACCAR 12-SPEED AUTOMATED TRANSMISSION


Purpose-built to work seamlessly with the MX-13 engine, the new PACCAR 12-speed automated transmission represents a major advancement in powertrain performance, productivity, efficiency, driveability and return on investment. Designed with the operator in mind, it boasts a torque capacity of 1850 lb-ft and is rated to 50 tonnes GCM.

SMARTER BY DESIGN


PACCAR’s proprietary 12-speed automated transmission features a weight-saving robust aluminum housing and coolerless-lubrication system, the 1,850 lb-ft torque-capable heavy-duty transmission weighs almost 50kg less than comparable automated transmissions. Fully integrated communication between the engine and transmission smooths operation.

SIMPLIFIED MAINTENANCE


The PACCAR transmission greatly reduces downtime and maintenance cost. Your first lube change interval occurs at 750,000km and requires just 9.1 litres of oil. A greaseless 430mm self-adjust clutch is maintenance free. The input shaft wear sleeve can be replaced quickly and easily – without a costly and time-consuming teardown.

SOLID SUPPORT


The PACCAR Transmission is quality-manufactured for a long service life and comes with a three year/750,000km warranty. The clutch carries a three-year/600,000km warranty. Several extended protection plan options are also available. Comprising more than 50 regional and metropolitan locations, PACCAR has built an extensive truck dealer network across Australia, New Zealand and Papua New Guinea that is renowned for its professionalism and excellence in the heavy duty truck industry. In addition, PACCAR offers 24/7 emergency roadside assistance through its Vehicle Support Center for as long as you own your truck.

PRECISION-BUILT FOR GREATER EFFICIENCY, PRODUCTIVITY AND
PROFITABILITY


These innovative design enhancements result in an automated transmission that delivers significant longterm operating advantages to owners and operators of PACCAR-powered trucks.

DRIVING SMARTER


Of all the variables that contribute to an efficient operation, how well a truck can be driven is still the one factor that matters most.


IMPROVED DRIVER PERFORMANCE


Optimised shifting and clutch engagement makes the vehicle easier and more productive to operate. PACCAR’s automotive-style column shifter allows the driver to keep both hands on the wheel and their eyes on the road, concentrating on traffic and the road ahead.


BETTER FUEL ECONOMY, FLEET-WIDE


PACCAR’s new automated transmission constantly monitors changes in road grade, vehicle speed, acceleration, torque demand, weight and engine load to keep the truck in the most fuel-efficient gear possible.


STEERING COLUMN MOUNTED STALK


The PACCAR Automated Transmission comes standard with a highly ergonomic, automotive-style column shifter that is simple  and intuitive to operate. Transmission controls include Drive, Neutral, Reverse and Manual modes as well as a selector for the engine brake.

INTELLIGENT TECHNOLOGY


Intelligent technology simplifies operation and improves performance.

PACCAR’s automated transmission comes with a suite of impressive technology features designed to make it easier to deliver your loads as cost effectively as possible.

HILL START AID

Prevents unintended roll back or roll forward. When the grade exceeds the programmed threshold, foundation brakes hold the truck for a controlled launch. It works when pointing uphill in drive or facing downhill in reverse.

AUTO NEUTRAL

Automatically switches the transmission into neutral once the parking brake is engaged to prevent potential movement.

ENGINE OVERSPEED PROTECTION

The transmission system upshifts if necessary to prevent engine over-speeding in Drive, Manual and Low modes.

ENHANCED ENGINE BRAKING

Downshifts the transmission to help slow the truck on long, steep descents and increases brake pad life.

URGE TO MOVE

Drivers simply release the brake pedal to automatically move forward, similar to the feel of a passenger car.

CREEP MODE

Enables the driver to “creep” at low speeds, offering ultimate control.

NEUTRAL COST

Fuel-saving feature that disengages the driveline on slight downhill grades.

OPTIMISED GEAR SELECTION

The transmission selects the appropriate starting gear and makes
optimised shift decisions, skip shifting when appropriate, based on grade, vehicle weight, engine torque and throttle position.
