External shift mechanism

The MTX-75 manual transaxle is a "2-shaft transmission".

MTX-75 means:

  • M: Manual
  • T: Transmission
  • X: Transaxle (front wheel drive)
  • Distance between input and output shaft in mm

The MTX-75 manual transaxle has been revised for vehicles equipped with the 2.0L Duratec RS.

The new features are:

  • New external shift mechanism
  • A limited slip differential.

Sets of floating helical gear pinions mesh to provide the normal speed differential action. To preload the gear-packs there is a selection of centre spring discs available. In the event of wheel spin, torque bias is generated by the axial and radial thrusts of the pinions in the pockets of the housing. The resultant friction force enables the driving road wheel and the differential side gear to transmit a greater proportion of torque.

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

The input shaft and output shaft are each seated in one roller bearing in the transaxle housing section on the clutch side and one roller bearing in the transaxle housing section on the transaxle side.

The output shaft drive pinion is in constant engagement with the differential drive annulus and is part of the output shaft.

The third and fourth gear wheels and the third and fourth gear synchronizer are located on the input shaft. The first, second and reverse gear teeth are part of the input shaft.

The first, second, fifth and reverse gear wheels and the first and second gear synchronizer and the fifth and reverse gear synchronizer are located on the output shaft. The third and fourth gear teeth and the drive pinion are part of the output shaft.
