Honda's older transmissions such as the Hondamatic semi-automatic transmission and its successors use traditional, individual gears on parallel axes like a manual transmission, with each gear ratio engaged by a separate hydraulic clutch pack. This design is also noteworthy because it preserves engine braking by eliminating a sprag between first ...
The Honda automobile torque converter had a lockup, leading the company to sell the original Hondamatic (which had just two forward gear ratios) as a three-speed. The true three-speed H3 was launched in 1979. In 1982 Honda introduced a four-speed fully-automatic (called Hondamatic Full-Auto), followed by a fully-automatic three-speed in 1983 ...
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.

A continuously variable transmission (CVT) is an automated transmission that can change through a continuous range of gear ratios, typically resulting in better fuel economy in gasoline applications. [1] This contrasts with other transmissions that provide a limited number of gear ratios in fixed steps.
The four shaft H5 transmissions are much more robust and do not exhibit the same failure rate as the three shaft H5. The new design first entered service in the 2005 Acura RL. All heavier vehicles eventually moved to this design in the following years until it was ultimately replaced by the H6, which also uses four shafts.
The designation of wide versus close ratio affected the lowest gear ratio; [7] for example, the four-speed Muncie transmissions offered in General Motors performance vehicles included the M20 "wide ratio" transmission, which had a first gear ratio of 2.52 or 2.56:1, while the M21 and M22 "close ratio" transmissions had a first gear ratio of 2. ...
