The Hondamatic (also called the H2) was Honda's first Automatic transmission. It was produced from 1973 through 1979. The Hondamatic name is used on all automatic transmissions from Honda.
The original Hondamatic, like all following Honda automatics, featured sliding gears on parallel axes rather than Planetary gear 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 Honda H3 transmission was launched in 1979.
Applications:
- 1973–1980 Honda Civic
- 1976–1979 Honda Accord
- 1979 Honda Prelude
Motorcycle
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 Clutch is needed.
Applications:
- 1976-1978 CB750A
- 1978 Honda Hawk
- 1979-1981 Honda CM400A
- 1982-1983 CM450A Hondamatic
Scooter, ATV, and power equipment
Honda also applies the Hondamatic name to a Hydraulic piston-based Continuously variable transmission used in Motorscooter, All-terrain vehicle, and other types of Power equipment.
