Caterpillar Inc is developing a complete line of fully automatic, planetary transmissions designed specifically for vocational applications.
It plans to begin production of these transmissions later this year, with availability in 2006. The new vocational on-highway transmissions are based on existing transmissions that have proven themselves in Caterpillar articulated trucks.
The six-speed CX31 transmission will be compatible with Caterpillar C11, C13, and C15 engines. The eight-speed super-heavy-duty CX35 transmission will match up with higher horsepower C15 ratings for on-highway vocational trucks.
Warranty and extended-service coverage for the transmissions will be matched to the engine.
