General Information: Notes

The newly-developed F4A41 and F4A42 automatic transaxle have been used.

These newly-developed transaxles combine the highest-precision electronic and mechanical technology to provide a new era in automatic transaxle performance.

The main features of these new transaxles are described below:

  1. The "INVECS-II" automatic transaxle system seeks to provide the ultimate in easy driving.
  2. Feedback control and learning control are incorporated into the control for all gear shifting clutches to provide an excellent shift feeling that suppresses shifting shocks throughout the vehicle.
  3. The gear shifting clutches use a hydraulic balancing mechanism to enable gear shifting at extra-high engine speed.
  4. The number of shafts has been decreased to two. Increased use has been made of metal plates. These features help to reduce the weight of the A/T assembly.
  5. Increased meshing ratios and improved rigidity of the gear supports and casing result in less noise.
