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 8L 90 is the first 8-speed automatic transmission built by General Motors. It was debuting in 2014 and is designed for use in longitudinal engine applications either attached to the front-located engine [ 3 ] with a standard bell housing or in the rear of the car adjacent to the differential (as in the Corvette).
HydraMatic Division calls the Roto a four-range, three-gear HydraMatic. It counts the stator multiplication at 3.50:1 as a first gear, and when road speed and the two coupling halves’ speed match, it counts the same gear with fluid now passing straight through the stator as 2nd gear at 2.93 to one.
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 ...
The Tremec TR-6060 six-speed manual transmission features six forward speeds and one reverse speed. It is derived from the Tremec T-56 6-speed manual transmission. As usual, the forward helical cut gears are synchronized. However, the reverse gear operates through a fully synchronized constant-mesh system.
The 4HP is a 4-speed Automatic transmission family with a hydrodynamic Torque converter with an electronic hydraulic control for passenger cars from ZF Friedrichshafen AG.In selector level position "P", the output is locked mechanically.
Compared to the 6-speed ZF 6HP transmission it uses 12 % less fuel, and 14 % less than a 5-speed transmission. [ 11 ] [ 12 ] Due to changes in internal design, the shift times have reduced to 0.2 seconds; additionally, the unit brings the ability to shift in a non-sequential manner – going from gear 8 to gear 2 in extreme situations simply by ...
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:
