Abstract
A torque converter clutch (TCC) release fluid lubrication system for a motor vehicle transmission includes a first fluid line, a second fluid line and a third fluid line. The first fluid line supplies TCC apply fluid to the TCC. The second fluid line receives TCC release fluid from the TCC. And the third fluid line supplies a first lubrication fluid to the transmission. The TCC release fluid and the first lubrication fluid combine into a second lubrication fluid that is fed into the transmission.
