The Eaton AutoShift transmission, an automated manual transmission, offers a blend of manual and automatic features. While some drivers initially perceive slower acceleration compared to a traditional manual, this is often an illusion of control. AutoShift transmissions can accelerate just as quickly, and they can be programmed for specific shifting and acceleration needs. Positive experiences with the 2017 UltraShift model, a variant of the AutoShift, highlight its performance capabilities despite some online criticism.
Eaton AutoShift: Addressing Common Concerns
One reported issue with the UltraShift involves difficulty rocking the vehicle when stuck on ice, a situation where a manual transmission might also struggle without additional traction. A key question for current drivers is how newer AutoShift models compare to the UltraShift, particularly regarding reliability and performance. For drivers who prioritize ease of use and safety over mastering manual shifting, an AutoShift transmission, especially in an 18-speed configuration, presents an attractive option. The allure of testing a 10-speed Allison transmission with a B-train further underscores the interest in automated shifting technology for heavy-duty applications.
Another concern revolves around a potential “lock-up” issue if the engine is accidentally turned off while in gear. Additionally, some AutoShift users experience difficulties with upshifting in automatic mode, particularly on soft roads or with heavy loads. This necessitates manually shifting or pushing the engine to higher RPMs (1600-1800) to force a shift, suggesting a possible need for setting adjustments.
Eaton AutoShift Transmission Longevity and Maintenance
While the AutoShift offers convenience for drivers of all skill levels, questions remain about its long-term durability and maintenance needs. Intermittent upshifting failures, even on highways, raise concerns about reliability and potential underlying causes. Understanding the typical lifespan of an AutoShift transmission before requiring major repairs is crucial for prospective buyers. Sharing experiences and insights regarding long-term use and maintenance can help drivers make informed decisions about choosing an AutoShift transmission. This information is vital for both individual drivers and fleet operators considering the AutoShift for their vehicles.
