INDIANAPOLIS — Allison Transmission’s latest fuel economy technology is now available for its 1000 Series and 2000 Series transmissions.

Referred to as xFE, designating extra fuel economy, the fully automatic bus and truck transmissions have demonstrated improvements of up to 7% when compared to baseline models, according to Allison.

“Other than our electric hybrid products, xFE models represent the very best fuel economy technology we offer,” said John Coll, senior vice president of global marketing, sales, and service for Allison Transmission. “Our goal with this expansion of the xFE portfolio is to also now achieve the best fuel economy from an automatic transmission in smaller, medium-duty buses and trucks.”

The 1000 Series and 2000 Series xFE transmissions have the same space claim and ratings as current models, but they incorporate a redesigned torque converter damper coupled with the FuelSense 2.0 Max package. The damper enables first range lock-up, delivering significantly more lock-up operation and operating at lower engine speeds in higher ranges to further improve fuel economy, according to Allison. All xFE transmissions are compatible with alternative-fuel engines.

“The new design works to achieve enhanced fuel economy in start-stop dense, low average speed duty cycles,” Coll added.

First announced in 2015, xFE transmissions were exclusively available in the 3000 Series for bus applications. The new models represent the first expansion of the xFE portfolio and come standard with FuelSense 2.0.

    ALLISON HAD THE PERFECT TRANSMISSION in the 1950s - 1960s - early 1970s. * MT30 & MT40 SERIES * 6 - SPEED * LOCKING TORQUE CONVERTOR * GRADE RETARDER * OIL & HIGH EFFECIENCY FILTER CHANGED REMOVING ONE 9/16 BOLT * I had13 transmissions & several million miles without a single failure. (Impossible to achieve with any GM ALLISON built after the 1971 &1973 new transmissions were introduced) Any one else have a comment?
