Manual Transmission - Overview: Overview

The IB5 transmission has an aluminum transmission housing which comprises of two sections. Its rigidity has been improved with the inclusion of reinforcement ribbing in the design. The transmission housing sections come in pairs and cannot be obtained separately. The clutch is hydraulically actuated.

All the gears are constant mesh gears (except reverse gear). In each gear, the required transmission ratio is achieved by means of a pair of gears.

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

The gears are all helical gears (except reverse gear). They all have synchronizers (except reverse gear) and run on plain bearings.

First and second gears have dual synchronizers.
