ZF S6-53 transmission
The ZF S6-53 is a 6-speed manual transmission manufactured by ZF Friedrichshafen AG. It is designed for longitudinal engine applications, and is rated to handle up to 600 newton-metres (443 lbf⋅ft) of torque.
Specifications
[edit]For all six forward gears and reverse, the ZF 6S-53 uses synchronizers, with one to three cones clutches depending on the gear. The bell housing and case of the unit are made of die cast aluminum. Installed on the transmission are a Hall effect sensor for input rpm, an oil temperature sensor, a reverse engagement sensor, a neutral sensor, and an electric oil pump. At high temperatures, the car's engine control unit activates the pump, sending the oil to a heat exchanger for cooling.
The gearbox uses an input, main, and layshaft configuration. Idler gears for speeds 1, 2, and 6 are on the layshaft while idler gears for 3 and 4 are on the main shaft. Gear 5 is direct drive. The main and layshafts are hollow for weight savings. The shafts are supported by a combination of ball and roller bearings.
The gear engagement is configured differently than many other rear-wheel drive manual transmissions. Instead of using one rod as gear selector and two more rods to move the forks, the 6S-53 uses a single rod to move the four forks, which are hinged on two screws in the gearbox case. While a given fork is actuated, ball detents and pins inhibit movement of the other forks.
The transmission weighs approximately 50 kg (110 lb).[1]
