Tapping noise from the manual transaxle when the clutch is engaged in any gear after engine start.

 

This concern may be caused by the reverse idler gear being damaged under the following driving condition.

If the wheels are spinning at a high speed in reverse on a frozen surface and the gripping force is recovered for both wheels at the same time on a dry surface, the impact load applied to the transaxle could be momentarily excessive, causing a tooth to break on the reverse idler gear.

NOTE: In the worst case, the vehicle may not move in reverse gear.

The material of the reverse idler gear has now been changed to meet this sort of driving condition.

 

REPAIR PROCEDURE

  1. Confirm with the customer that the driving condition mentioned above is when the noise started.
  2. Confirm that the noise occurs when the clutch is engaged with the engine running.

NOTE: If the primary shaft rotates, the reverse idler gear spins so the noise occurs in any gear.

  1. Replace the transaxle assembly according to the instructions on MS3 online or the Workshop Manual (section 05-15).
