Apparatus and method of filling an automatic transmission with working fluid

摘要

A top off fill wand assembly for adding and removing operating fluid from an automatic transmission for a vehicle having a flexible fluid fill line for snaking through a transmission fill tube which incorporates a tip assembly with a metal electrical contact at the tip. The contact of the tip with the bottom of the oil pan completes electrical circuitry activating top off operation. The tip has a port which corresponds to indicator stick level measurement system. If level is low, the fill wand delivers fluid to the sump until the port is reached, and if level is high, the wand removes fluid until the level is obtained.
