Abstract
An integral stand tube for regulating fluid level within a transmission is provided. The stand tube includes an upper opening, at least one lower opening, and an internal volume defined by at least one internal passage for directing fluid from a valve body-side of a transmission to a main sump located on a gear-side of the transmission. The lower opening is operatively connected to a thermal valve assembly and a fluid passage formed in the transmission case between the auxiliary sump of the valve body-side and the main sump of the gear-side. Fluid passing from auxiliary sump to main sump bypasses dynamic transmission components to thereby minimize fluid aeration due to contact therebetween.
