Eaton extends fluid service interval for school bus transmissions

Power management company Eaton has announced an extension to its fluid lubrication service maintenance interval for its Procision line of medium-duty dual clutch transmissions for school bus applications that will lower or even eliminate fluid changes.

The new interval is now 10 years/150,000 miles, a change from three years/150,000 miles that was announced when Procision was launched, the company said. The new preventive maintenance interval extension is enabled by the synthetic fluid used in Procision, the lifetime sump filter, and relatively low heat generation associated with dual clutch technology, Eaton added. 

“This change makes it possible that a school bus fleet may never have to service a Procision transmission depending on their duty cycles,” said Jeff Walker, director, Commercial Powertrain, Eaton’s Vehicle Group. “With the average cost of a transmission fluid and filter change of $250, this new extended interval change can save a fleet $583 versus competitive offerings.”

“With the fuel efficiency and low maintenance costs, Procision transmissions promise to deliver the lowest total cost of ownership for any medium-duty transmission in the school bus market today,” added Walker. “This is a world-class transmission that helps deliver safe, confident and easy operation for any school bus driver by delivering optimal performance in many driving environments.”
