Abstract
In a transmission for an internal combustion engine including an oil sump and an oil pump operatively in communication with the oil sump, an oil reservoir is provided for receiving oil from the oil sump when the transmission is in direct drive and power is transmitted only through the main shaft of the transmission while the intermediate shaft is idling so that no friction is generated by the gears of the intermediate shaft being immersed in the oil of the oil sump.
