A torque converter cannot achieve 100 percent coupling efficiency. The classic three element torque converter has an efficiency curve that resembles ∩: zero efficiency at stall, generally increasing efficiency during the acceleration phase and low efficiency in the coupling phase.
The 8HP 70 transmission with the gearset 4 in 23-85-teeth-configuration was the pilot series and therefore without generation designation. It was first used in the BMW 7 Series (F01) 760Li, has a torque handling limit of 700 N⋅m (516 lb⋅ft), and weighs 87 kg (192 lb).
The 8L 90 is the first 8-speed automatic transmission built by General Motors. It debut 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 mounted in the rear of the car adjacent to the differential (as in the Corvette).
In the 1970s, thanks to new torque-converter developments with improved traction characteristics, (approaching the start-up traction) a two-converter transmission was designed to replace the previously used three-converter transmission. And even today, torque-converters are still being improved, although they have reached an advanced stage.
The aluminum die-cast case is 10 % lighter, yet 30 % more rigid, even with two additional gears and a 22 % greater torque capacity the new transmission weighs 95 kg (209 lb) or 10 % more than the previous unit. With new micro-laser technology gear tooth production tolerances have been reduced 50 %.
As the selected gearset concept saves up to 2 components compared to 5-speed transmissions, the advantages clearly outweigh the disadvantages. It has a torque converter lock-up for all 6 forward gears, which can be fully disengage when stationary, largely closing the fuel efficiency gap between vehicles with automatic and manual transmissions.
