Allison Transmission says new prognostic features are now available on its 1000/2000/3000/4000 series models. Calibrated to particular truck operating requirements, they monitor various operating parameters to determine — and ‘send’ an alert — when a specific maintenance function is required. Use of Allison-approved TES 295 transmission fluid is required.

New features include the Oil Life Monitor. Based on the vehicle’s duty cycle, it determines fluid life and alerts the operator when a change is needed. The Filter Life Monitor warns when the transmission’s fluid filter(s) need to be replaced, which may help extend filter change intervals. And the Transmission Health Monitor determines when clutch maintenance is required.

When service is due for Allison 3000/4000 Series models, a wrench icon on the shift selector’s digital display alerts the operator. Similar to checking oil level and diagnostics, the status of all three prognostic features can be checked by toggling through the shift selector’s display. The 1000/2000 models require a separate transmission service light to alert the operator.
