Difficult to

Causes for difficult gear shifting are classified to troubles concerning the control system

intermesh gears

and transmission

When the gear shift lever is heavy and it is difficult to shift gears

clutch disengagement

may also be unsmooth

First make sure that the clutch operates correctly and inspect the transmission

In the most case this trouble occurs when the interlock plunger check ball and or spring is worn or weakened or when the control system is defective

In this case

the trouble cannot be corrected by replacing gears

and therefore trouble
