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

MTX-75 means:

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

The MTX-75 manual transaxle has been revised for MY 2001.

The new features are:

  • New external shift mechanism
  • New output shaft design (the output pinion is part of the output shaft)
  • Modified clutch side transaxle housing adapted to the new engines

Reverse gear wheel

In neutral, none of the gears is 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 drive pinion of the output shaft is constantly engaged with the differential crownwheel and is part of the output shaft.

The third/fourth gear synchroniser assembly is on the input shaft.

The synchroniser assemblies for the first/second gear and fifth/reverse gear are on the output shaft.

The output shaft teeth are part of the output shaft. The teeth for third and fourth gears are no longer part of the output shaft (one piece design).
