    It was Hideo Sugiura, the general manager of Honda R&D. "We want to develop an automatic transmission for use in an automobile," he said, "and we want.

    While most (all?) other automatic (not CVT) transmissions use planetary gear- sets, Honda has used a mainshaft/countershaft arrangement of spur gears, not.

    Pinging is currently not allowed. Honda, however, had no experience with hydrodynamic torque converters, though some previous models had used hydraulic mechanisms. 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. Hattori was excited about the prospect of realizing a dream, but he was also thankful that Sugiura made a trip to the hospital to give him the good news.

    Hondamatic - Wikipedia

    Honda has long built nearly all of its own automobile transmissions , unlike many other automobile manufacturers which often source transmissions from external sources. Honda's automatic transmissions are unusual in that they do not use planetary gears like nearly all other makers. Instead, the Hondamatic 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 and second gears. Honda was forced to invent their new system due to the vast array of patents on automatic transmission technology held by BorgWarner and others. Honda initially chose to integrate the transmission and engine block for its first application in the N as in the Mini.

    The Hondamatic incorporated a lockup function, which Honda called a third ratio, and had manual gear selection.

    The company's early transmissions also used a patented torque converter 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.

    These "opposing" pressures caused the gear changes through the free floating gear change valves. The typical torque multiplication of the c 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. It was initially announced in Europe as an automatic as the staff at Honda in Europe assumed that it would like the N be fully automatic. This was quickly changed to "Hondamatic".

    The company's naming scheme is also confusing, as it is specific to a single model of vehicle and some identifiers are reused. From Wikipedia, the free encyclopedia.
