What is a Lockup?
A lockup is one more clutch that is located in the torque converter and that starts working if you are reaching high amounts of revolutions or mostly it starts working when you are in third gear. That is important to get a closed connection from the engine to the transmission. Like that you are able to prevent the loss of RPM s and the resulting use of too much fuel. As long as the lockup doesn t work, there is no stable connection between engine and transmission. The power is transferred through two paddle wheels by the oil as a medium. One paddle wheel is driven by the engine and the second by the oil stream. The two paddles are located on the inside of the torque converter. They are only connected by the medium oil and that is why there are different amounts of revolutions of the engine and the transmission. The lockup overrides when there is a higher amount of revolutions. If there is only a small difference between the input and output revolutions that means a clutch in the torque
