The ZF EcoLife 6AP1700B is a fully automatic, six-speed transmission designed specifically for low-floor city buses, intercity coaches, and heavy commercial vehicles with a gross vehicle weight (GVW) between 12 and 26 tons. It is the successor to the iconic Ecomat series, offering improved fuel efficiency, lower noise levels, and enhanced electronic control.

• Use only ZF-approved oils (EcoFluid M or LifeExtend).
• Replace internal filter at every oil change.
• Check retarder valve clearance (if adjustable).
• Update TCU software during major service (ZF diagnostic tool required).

The use of helical teeth in the planetary gearsets minimizes transmission noise, making for a quieter ride for passengers and reduced noise pollution in city centers.
