|Class||2-speed transverse automatic transmission|
- See also list of Honda transmissions for other Hondamatics
The original Hondamatic, like all following Honda automatics, featured sliding gears on parallel axes rather than planetary gears like most other automatic transmissions. The design is noteworthy because it preserves engine braking by eliminating a sprag between first and second gears. It also featured a unique shifting action controlled by stator torque rather than traditional hydraulics. The Honda torque converter had a lockup, leading the company to sell the original Hondamatic (which had just two forward gear ratios) as a 3-speed. The true 3-speed H3 was launched in 1979.
The Hondamatic was later used in Honda's 400, 450 and 750 cc motorcycles, including the CB750A. In this application, it is not a true automatic transmission. The rider must manually select one of the two gears, though Honda's torque converter means that no clutching is needed.
