<p>A hand-held transmission fluid changer (10) includes a compact housing (12) internally plumbed with a pair of open ended drain (14) and supply (16) tubes for connection at respective first ends (32, 30) with the first ends of a pair of hoses connected at their opposite ends with remote waste and unused fluid tanks. The respective tubes include respective second ends (36, 34) for connection with a second pair of tubes leading to respective upstream and downstream transmission components for, respectively, withdrawing used fluid from and introducing unused fluid to a transmission. A demand pump is connected in fluid circuit with the supply hose to flow unused fluid from the unused fluid tank to the supply tube. A pair of flow control valves (26, 28) are disposed in the respective tubes (14, 16) to allow the operator to adjust and match the respective flow rates through such tubes (14, 16).</p> |
