MANUAL TRANSMISSION SYSTEM


  1. CONSTRUCTION


    1. Gear Train


      1. The transmission synchromesh mechanism is an all-speed constant mesh type.

    2. Shift Control Mechanism


      1. The shift control mechanism uses the semi-direct method to achieve short stroke and good rigidity.

      2. Friction is lowered during operation by the adoption of slide ball bearings in the shift fork shaft support part, improving the feel of shifting while driving as well as when at a standstill.

      3. Resin or leather gearshift lever knob is available according to specifications.

      4. The reverse miss shift prevention mechanism prevents shifting into reverse unless the shift lock release collar provided on the shift lever is raised.

      5. A pull-collar gearshift lever has been adopted to prevent incorrect operation while in forward or in reverse.

      6. A stopper cover is provided on the 1st-2nd side, so that the pull collar must be pulled upward in order to shift into reverse. This reduces the amount of shift effort and ensures a precise shifting operation.

    3. Shift and select mechanism


      1. The shift mechanism has 4 shift forks, 5 shift fork shafts, and an interblock.

      2. Friction is lowered during operation by the adoption of slide ball bearings in the shift fork shaft support part, improving the feel of shifting while driving as well as when at a standstill.

      4. All shift forks in the shift fork shaft slide mechanism are fastened to the shift fork shaft, and a system whereby the entire fork shaft slides has been adopted, reducing friction during operation.

      5. A ball plunger shift detent has been adopted for the shift detent mechanism, and a non-linear cam that enables quick select operation through negative slope characteristics and by clarifying the neutral gear position has been adopted.
