Voith DIWA

The Voith DIWA automatic transmission was designed by Voith primarily for city-buses and suburban buses.

The transmission utilizes a Differential-Wandler (Converter) or DIWA which replaces two gears which would be used on a conventional transmission.

Voith has designed many variations and generations of the Voith DIWA transmission.
