Best Answer: Torque is a twisting force. It is the power output of an engine at one specific point in time. The first number, 200 in your expample, is the amount of torque. In America is is measured in foot/pounds. The second number, 400 in your example, is the RPM where that torque number occurs.
A torque converter is the fluid coupling between an engine and transmission that allows the engine to idle at low speed without engaging the transmission.A torque converter uses an engine-driven turbine (fan) to push fluid through a matching turbine attached to the transmission.ransmissions can shudder in a very similar manner to torque converters. To determine whether the shudder is tranny or TC related, run your vehicle for a little while till it begin to shudder and immediately park it. With your foot on the brake, put the transmission in Drive, and apply light throttle.
