Abstract:
A transmission fill gauge system for a vehicle transmission includes a fill gauge assembly and a vacuum adapter assembly, wherein the vacuum adapter assembly and the fill gauge assembly are configured to be simultaneously in fluid communication with a transmission drain pan of the vehicle transmission. A method of measuring a transmission fluid level in a drain pan includes fluidly connecting a vacuum adapter assembly between a fill port of the vehicle transmission and a constant vacuum source, applying an internal vacuum pressure to the drain pan via a constant vacuum source, removing a drain plug from a drain on the drain pan, attaching a fill gauge assembly to the drain, the fill gauge assembly having a primary fluid tube slidably mounted in an elongated body portion, sliding the primary fluid tube to a predetermined position, and discontinuing the internal vacuum pressure to the drain pan by closing the valve.
