, Canadian-produced Classic buses derived from the
GM New Look
The GM New Look bus is a municipal transit bus that was introduced in 1959 by the Truck and Coach Division of General Motors to replace the company's previous coach, retroactively known as the GM "old-look" transit bus.
Also commonly known by ...
, and Grumman Flxibles. Later production buses in the GM and Flxible line had the Allison V731 transmission, which is essentially the same unit but controlled electronically, with a keypad replacing the familiar shifter-lever in the driver's compartment.
The Allison V730/V731 family transmissions moreover come in versions with a built-in retarder (the VR731), and a version allowing transit agencies and others to use right-turning Detroit Diesel family motors (variously the V731R or V731RH) instead of the standard left-turning units found in Flxibles, GM New Looks and RTS equipment.
Most installations of the V730/V731 have them coupled to the DDA 6V92TA two-stroke diesel engine, with the exception of GM 'Classic' T6H-5307 buses produced in Canada, where these were instead mated to the then-standard 6V71N engine. Some Canadian production 1982 "New Look" models featured the 6V92 mated to the V730, such as Vancouver, B.C.'s 1982 T6H-5307 "Hillclimber" buses. An example resides at "TRAMS" in British Columbia.
