Manual Transmission/Transaxle: Description and Operation

Part 2 Of 2:

The MTX-75 manual transaxle is a "2-shaft transaxle".
MTX-75 means:
- M: Manual.
- T: Transmission.
- X transaxle (front wheel drive).
- 75 Distance between input and output shaft in mm.

The aluminum transaxle housing consists of two closed sections. The reinforcing ribs on the transaxle housing have been revised to reduce noise and vibration. As a result, the preload on the shafts and differential bearings has also increased.

To improve the lubrication of the third gear wheel, an additional drip plate has been fitted to the selector fork, allowing more transaxle fluid to drip onto the third gear synchronizer rings.

With the "2-shaft transaxle", all the gears are in permanent mesh. In each gear the required transaxle ratio is achieved by means of a pair of gears.

When the reverse gear is selected, the direction of the output shaft is changed by an idler gear.

The input and output shafts turn on taper roller bearings.

To further improve stability and gearshifting, the selector mechanism has been revised to incorporate a maintenance-free cable operating mechanism.

All the gears, including reverse, are bevel-cut, synchronized and turn on needle roller bearings.

First, second, and third gears have double synchronization. The advantages of this are that the transaxle operates quietly, gearshifts are smooth, and the assembly is compact and light weight.
