The KM164 is an 5 speed manual transaxle which was fitted to TM model Magnas.
The KM164 is interesting as it uses a vacuum servo to select what is seen by the driver as 5th gear, which is achieved by changing a gear on the input shaft. When 5th gear is activated - the transmission remains in 4th gear and the high ratio on the input shaft is selected. Essentially the transmission in the transaxle is a high/low ratio unit, however this is only ever used when the vehicle is put in and out of 5th gear unlike some other vehicles.
