Power Flow


Engine torque is transferred from the clutch to the input cluster gear shaft. The four forward gears on the input cluster gear shaft are in constant mesh with a matching gear on the main shaft. The 4th gear on the input cluster gear shaft is simultaneously meshed with the 5th speed gear on the 5th gear shaft. These meshed gearsets provide the five available forward gear ratios.

Both the main shaft and the fifth gear shaft have a pinion gear, which is constantly engaged with the final drive ring gear on the differential assembly. If one of the gears (1 through 4) on the main shaft is selected, and that gear is locked to the shaft by its shifted synchronizer, then the input cluster shaft gear will drive the main shaft pinion gear; driving the differential final drive ring gear. If the 5th gear is selected the input cluster shaft 4th gear will drive the 5th gear shaft pinion gear; driving the differential final drive ring gear. At this time, the main shaft gears will rotate freely.

The gear ratios are as follows:

1st 3.21:1

2nd 2.09:1

3rd 1.37:1

4th 1.02:1

5th 0.75:1

Rev. 3.42:1

Final 3.74

The 5th gear range provides a ratio, in which, the input speed (rpm) from the engine is less than the transaxle output speed to the differential.

REVERSE is accomplished by moving an idler gear into mesh with the input cluster shaft gear and the reverse sliding gear on the main shaft. The reverse idler gear acts as an idler and reverses the direction of main shaft rotation.

In NEUTRAL, none of the gears on the main shaft or the 5th gear driveshaft are locked to their shafts. No torque from the engine to the input cluster gear shaft is transferred to the differential assembly and to the wheels through the halfshafts.
