Manual Transmission/Transaxle: Description and Operation

Manual Transaxle





The MTX 75 manual transaxle is a 2-shaft transaxle.
MTX 75 means:
^ M = Manual
^ T = Transmission
^ X = Transaxle (front wheel drive)
^ 75 = The distance from the input and output shafts in mm

The aluminum housing consists of two closed sections. The reinforced ribs on the transaxle housing are to reduce the noise and vibration. With the '2-shaft transaxle' all the gear wheels are in permanent mesh. In each gear the required ratio is achieved by means of a pair of geared wheels. When reverse is selected, an idler gear changes the direction of rotation of the output. The input and output shafts run taper roller bearings. To further improve stability and gear shifting, a maintenance free cable operating mechanism is used. All gear wheels, including reverse gear, are beveled cut, synchronized and run on needle roller bearings 1st, 2nd, 3rd, gear have doubled synchronization.

The engine rotational torque is transmitted from the crankshaft through the clutch to the transaxle input shaft which then transmits drive to the output shaft by utilizing an arrangement of gears. When reverse gear is selected, the direction of the output shaft is changed by an idler gear assembly.

In neutral, none of the gears are connected to the input or output shaft through the relevant synchronizer unit. No torque is transmitted to the differential.
