Describe the function of a 'torque converter' in a heavy equipment transmission system and explain how its efficiency is affected by slippage.

The torque converter in a heavy equipment transmission system performs several crucial functions. Primarily, it acts as a fluid coupling to transmit power from the engine to the transmission. Unlike a direct mechanical connection, the torque converter uses hydraulic fluid to transfer power, allowing the engine to continue running even when the wheels are stopped. This prevents the engine from stalling. Secondly, it multiplies torque, especially at low engine speeds. This is achieved through the internal components of the torque converter: the impeller (pump),....
