An automatic transmission fluid exchanging device includes drain and supply tubes to conduct used transmission fluid from and unused transmission fluid to a vehicle transmission. The device further includes a supply pump in the supply tube to flow unused transmission fluid into the transmission. A pair of flow control valves are disposed in the respective drain and supply tubes to allow the operator to match the flow rates of fluid through the respective tubes.

A transmission fluid changer apparatus for tapping into a downstream transmission component downstream of an automatic transmission pump operative to pump transmission fluid at a predetermined rate and into an upstream component upstream of said transmission pump for removing used fluid from said transmission to a drain tank while pumping clean fluid from a supply tank to said transmission, said apparatus comprising: a housing; a fluid circuit mounted in said housing, including a drain tube for connection on one end to said drain tank and including on its opposite end a drain coupler for connection to said downstream transmission component for receiving transmission fluid at said predetermined rate and a supply tube for connection on one end to said supply tank and including on its opposite end a supply coupler for connection to said upstream component; a supply pump device connected to said supply tube for pumping clean transmission fluid through said supply tube; and a flow control device in said supply tube for controlling the rate of fluid flow through said supply tube whereby said drain coupler may be coupled with said downstream component and said supply coupler coupled with said upstream component, said transmission pump operated to pump used transmission fluid at said predetermined rate and said flow control device adjusted to control the flow rate of unused transmission fluid through said supply tube at a rate substantially equal to said predetermined rate.
