Y4M - Manual Transaxle

Transmission System Description and Operation

This 5-speed transaxle assembly adopts the synchronized mesh type of 5 forward speed. The reverse speed gear is driven by sliding idle gear without synchronizer.

Reverse Gear Mis-Shift Preventing Mechanism

It prevents the gear from directly being shifted from 5th to reverse when shifting to reverse from 5th. Shift to the reverse in neutral position to prevent the shift cam from being interfered to the shift guide bolt.





In case of shifting to 5th gear, shift and select shaft rotates to right that shift cam separates from guide bolt and moves upwards by returning spring. Therefore, shifting to reverse in this condition is impossible because of interference of guide bolt.





When shifting to reverse from neutral position between 5th and reverse, shift cam rotates to left and shifting is possible.





Differential

Differential is integrated with transmission case and installed on chassis together with engine. It changes the direction of power and increase torque by reducing speed.

Reduction gear is installed parallel to counter shaft and is helical gear type. Differential gear is bevel gear type and is integrated with reduction gear.
