| Allison MT643 Series |
|
Over twenty years of design have made today's Allison MT 643 a tough, economical and flexible transmission. The four-speed on-highway MT 643 combines smooth performance and heavy-duty reliability for mid-range trucks and buses. It is so efficient in traffic and over the road that it has made automatics the transmission of choice in vocations such as beverage and pickup and delivery. The MT 643 shifts smoothly through the gear ranges, with no interruption of power to the wheels. This helps improve trip times and provides excellent acceleration. A lockup mode in third gear helps improve fuel efficiency and engine braking at highway speeds. |
