, 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 and second gears. Instead of a sprag or roller clutch, Honda's older transmissions rely on pressure circuits to modulate line pressure to change gears. Honda was forced to invent their new system due to the vast array of patents on automatic transmission technology held by

which used stator force to reduce hydraulic losses by using a reaction arm to increase the hydraulic pressure when the stator was stalled. The reaction arm acted directly on the regulator valve this meant that increased pressure was available to the clutch plates when torque multiplication was greatest. The stator was equipped with a sprag clutch enabling it to freewheel when required. The N360/N600 controlled gear changes by balancing a throttle valve and a centrifugal valve. These "opposing" pressures caused the gear changes through the free-floating gear change valves. On October 18, 1967, the N360 AT model with the lock-up function was unveiled at the London Auto Show.(ref Honda Worldwide) It is not now clear if the lockup function made it into production; it was not fitted to the N600AT for Europe. The typical torque converter of the time was about 11.5in. long and the torque multiplication ratio was about 1.5 to 1. The N360/N600 torque converter was about 5.5in. long and achieved a torque multiplication of over 2.2 to 1. The first Civic was equipped with a manually changed hydraulically engaged two-speed transmission with a torque converter. This torque converter was nominally about 7in. and achieved a torque multiplication of c2.7 to 1. It also used the reaction arm on the stator as in the N360/N600 to increase hydraulic pressure. It was initially announced in Europe as an automatic as the staff at Honda in Europe assumed that it would like the N600 to be fully automatic. This was quickly changed to "Hondamatic". This gearbox was a separate unit and used ATF - Automatic Transmission Fluid. The company's naming scheme is also confusing, as it is specific to a single model of the vehicle and some identifiers are reused.
