ABSTRACT:
An oil storage reservoir has a fluid flow passage which returns fluid to the main transmission reservoir. The storage reservoir is supplied with fluid by the transmission control system and the amount of fluid that returns to the main reservoir from the storage reservoir is controlled by a thermally responsive valve mechanism such that, as the fluid temperature increases, the flow passage is reduced so that the level of oil in the storage reservoir is increased. Thus, the change in fluid volume, due to temperature change, is accommodated by the storage tank as controlled by the thermally responsive valve.
