Allison introduce second reverse gear
As part of an ongoing product optimization initiative, Allison Transmission will be introducing a second reverse gear on all Allison 4700 and 4800 models. This new feature offers a second ‘deep reverse’ in addition to the standard reverse to provide greater control and engine braking during operation on steep grades. Second reverse will also allow increased manoeuvrability when operating in confined spaces, providing quicker operation cycles and thereby boosting productivity performance.
The shorter ratios of second reverse will make uphill and downhill reversing much safer and easier in heavy-duty applications.
When a vehicle is in second reverse, it will have a slow creep capability with high engine speeds. With a mechanical ratio of 17.12, it will have an effective torque converter multiplied ratio up to 32.5:1. The new reverse gear will provide better overall performance for a variety of applications and will be available mid-2010.
