General View
The iB5 manual transaxle in the vehicle is a 2-shaft transaxle which has been revised to include a cable operating mechanism for the first time.
The aluminum transaxle housing comprises two sections. Its rigidity has been improved with the inclusion of reinforcement ribbing in the design. The transaxle housing sections come in pairs and cannot be obtained separately. The clutch is hydraulically actuated.
All the gears in the "2-shaft transaxle" are constant mesh gears (except reverse gear). In each gear, the required transaxle ratio is achieved by means of a pair of gear wheels.
When reverse gear is selected, the direction of rotation of the output shaft is changed by an 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.
The iB5 manual transaxle is filled with 2.3 liters of synthetic fluid, specification WSD-M2C200-C. The fill height is 5 to 10 mm below the lower edge of the check hole. Fluid changes are not necessary.
