Automatic vs. Manual Transmission 200

posted by  someone claiming to be Scott on  Mon Mar 17 17:45 CST 2003 [RELATED]

Generally speaking, less power is lost through the drivetrain in a manual transmission car. With an automatic transmission, the engine has to drive an oil pump (torque convertor) which in turn drives the transmission (it's a hydraulic system). The torque convertor must reach a certain stall speed (in engine RPM's) before the transmission input shaft begins to turn. With a manual transmission, the engine is essentially coupled directly to drive wheels when the transmission is in gear and the clutch is engaged. Far more efficient power transfer, and thus better fuel economy and performance.
