    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.

    This was due to Borg-Warner not having transmission specifications that was efficient enough for such a small engine like the cc Honda S and one that was able to be reliable at a maximum engine speed of rpm. Development had not been moving as he had expected, which brought on an anxiety attack. Take your favorite Honda MT model out for a drive and celebrate the joy of shifting 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. When testing and refinements had been made, Honda sold their first automatic transmission in the N

    It was late in Torao Hattori, who was developing the CVT for the T mini truck, was in the hospital after falling ill due to stress. Development had not been moving as he had expected, which brought on an anxiety attack. Hattori had a visitor at the hospital one day. Greetings were exchanged, after which an anxious Sugiura began to speak:. Hattori had designed semi-automatic transmissions for Mikasa when he was with the Yokohama-based Okamura Seisakusho.

    Since joining Honda he had been involved in the development of Patalini-type continuously variable transmissions for the Juno M80 and M85 series. However, his original intent in joining Honda was to design automatic transmissions for cars. 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. Even as he lay there in bed, he soon began conceiving ideas for a new automatic transmission.

    He was too anxious to wait until he could leave the hospital. In those days, several more-or-less practical AT specifications were available, based on different combinations of parts. The automatic transmission Hattori had in mind used a hydrodynamic torque converter and a transmission device. He came up with this combination because the torque converter was associated with good clutch performance and very smooth starting characteristics.

    Perspective view of the torque converter. Honda, however, had no experience with hydrodynamic torque converters, though some previous models had used hydraulic mechanisms. Moreover, the development and commercial implementation of a new technology would require that all departments involved in the process - from development through production - have a degree of relevant engineering expertise. To develop an automatic transmission that could accommodate the characteristics of its models, Honda also needed to obtain data on actual vehicles.

    For these reasons the development team decided to start by building a prototype car. This, they believed, would help them discern the basic facts. As for the automatic transmission itself, they decided to ask BW to develop a prototype.

    This approach was a natural choice, since Honda possessed little of the technology. And in light of the aforementioned difficulties, the environment surrounding AT development did not promise a positive result. Hattori quickly contacted BW with specifications he had drawn up based on the S He had been planning all along to increase development efficiency by using an existing AT specification as the basis and refining the details to satisfy requirements. The unexpected reply from BW was a wake-up call for Hattori and his colleagues.

    He recalled the words of Soichiro Honda, then president of the company: They must correct the problems they find, test them again and make corrections, and repeat the process.

    There was no way anyone could get an excellent result at the very beginning. This was especially true, given the fact that automatic transmissions were known to be less efficient with engines displacing cc or less. Yet, this unexpected turn of events rekindled the pride Hattori and his colleagues had as engineers.

    So, driven by the spirit of challenge, the development staff tasked with the creation of an AT began moving in a new direction. Copyright, Honda Motor Co. A Breakthrough in Original Thinking.
