Particularly noticeable are the too small step between 3rd and 4th gear and the too large one between 7th and 8th gear. This cannot be eliminated without affecting all other gear ratios. On the other hand the selected gearset concept offers 2 to 3 gears more than conventional transmissions of comparable manufacturing costs, which more than ...
The 9HP is only 0.24 inches (6 mm) longer than, and weighs 16.5 lbs (7.5 kg) less than, the outgoing six-speed transmission. The compact packaging is achieved by using a number of innovative design features: a new compact hydraulic vane-type pump, two patented dog clutches, [3] which replace bulkier conventional clutch packs, and a nested gear set.

It is able to encompass a torque range from 300 N⋅m (221 lb⋅ft) to 1,000 N⋅m (738 lb⋅ft), and is available for use in middle-class cars through to large luxury sport utility vehicles. [7] Since gearset 4 meshes in almost all gears up to and including 5th gear, large gear wheels are advantageous for durability.
The 6L 50 (and similar 6L 45) is a 6-speed longitudinally-mounted automatic transmission produced by General Motors.It is very similar in design to the larger GM 6L 80 and 6L 90, and is produced at GM Powertrain plants in Toledo, Ohio; Silao, Guanajuato, Mexico; and by the independent Punch Powerglide company in Strasbourg, France.
The 4HP 20 was introduced in 1995 and has been used in a variety of cars from Citroën, Lancia, Mercedes-Benz, Peugeot, and Renault. [1] The maximum torque capacity is 330 N⋅m (243 lb⋅ft ). The 4HP 22 was produced for vehicles with rear wheel drive or 4X4 layout.
Introduced in 1996, it has been used in a variety of cars from Audi, BMW, Porsche, and Volkswagen Passenger Cars.

As the large step is shifted due to the large span to a lower speed range than with conventional gearboxes, it is less significant. As the gear steps are smaller overall due to the additional gear(s), the geometric gear steps are still smaller than the corresponding gear steps of conventional gearboxes.
