Allisons Help Drivers And Drivelines

摘要

If there's any doubt in your mind that an automatic transmission is easier to drive, you should've been on a recent demonstration in the Wild West. Allison Transmission, now part of General Motors Powertrain, showed off its products' ease of operation and money-saving potential to an audience of tough-minded truck operators, and may have made some "converts. Marketers and engineers also explained a realignment of Allison medium- and heavy-duty products. They're now divided into a Highway Series (HS) and a Rugged Duty Series (RDS), and some have been uprated in horsepower and torque. Mechanically, the four-, five- and six-speed automatics are the same from series to series, with one exception: RDS models have provisions for power take-off gearboxes, so use longer cases with space for standard PTO mounts. There are also some warranty differences; RDS models, which Construction Equipment readers are more likely to use, are covered for two years and unlimited miles. HS products have specified mileage limits.
