The gear ratio also determines the transmitted torque. The torque ratio TR AB of the gear train is defined as the ratio of its output torque to its input torque. Using the principle of virtual work, the gear train's torque ratio is equal to the gear ratio, or speed ratio, of the gear
1st and 2nd are low ratios like in the W56 for use to get a heavy vehicle moving. 3rd ratio is the same as in the W57/W58 for a lower rpm drop between 3rd & 4th useful in high-speed acceleration. 4th is direct 1:1 as per design in these boxes. 5th seems to be the base W55 overdrive ratio. Ratios: First Gear: 3.954:1; Second Gear: 2.141:1

Manual – the driver has to perform each gear change using a manually operated clutch; Automatic – once placed in drive (or any other 'automatic' selector position), it automatically selects the gear ratio dependent on engine speed and load; Basically there are two types of engine installation:
A transmission (also called a gearbox) is a mechanical device which uses a gear set—two or more gears working together—to change the speed, direction of rotation, or torque multiplication/reduction in a machine. [1] [2] Transmissions can have a single fixed-gear ratio, multiple distinct gear ratios, or continuously variable ratios. Variable ...
After its introduction in 1984, the Justy was also available with 4WD and thus a different gearbox. The gear ratios for this gearbox were altered slightly. In 1994 the normal/FWD gearbox was dropped; one could only get a 4WD gearbox by then. Gear ratios: 1st 3.071 2nd 1.695 3rd 1.137 4th .771 5th .631, Rev 3.461 Final 5.200
The police package (9C1) B-body cars featured a First Gear Block Out (FGBO) Plate on the transmission housing to prevent drivetrain damage. The shift point for first to second gear is about 43 MPH (69 km/h) while second to third gear shift point is about 83 MPH (134 km/h) assuming a 3.08:1 differential and a 5,500 RPM engine speed limit.
The design of most manual transmissions for cars is that gear ratios are selected by locking selected gear pairs to the output shaft inside the transmission. This is a fundamental difference compared with a typical hydraulic automatic transmission, which uses an epicyclic (planetary) design, and a hydraulic torque converter.
