The EZ Module and your Transmission
The automatic transmission has a fluid-filled clutch-like device called a torque
converter. This device uses the spinning motion of the motor to drive the
transmission which drives your wheels. As the truck speed stabilizes, the
torque converter engages a mechanical connection which locks the two halves
of the torque converter, so the output shaft is going the same speed as the input
shaft. This mechanical linking of the two halves is called Transmission Lock-
up. If the motor produces too much power, this mechanical lock-up can start to
slip. When this slippage occurs, the EZ module reduces the power output to
allow the transmission to function properly. This is a great feature that provides
an extra level of protection for your vehicle.
