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 preserved engine braking by eliminating a sprag between the 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 three-speed. The true three-speed H3 was launched in 1979.
The Hondamatic was later used in Honda's 400, 450 and 750 cc motorcycles. In this application, it was not a true automatic transmission, as the driver had to manually select one of the two gears, though Honda's torque converter meant that no clutch was needed.
