Any Iriz manual owner here?
I'm Persona MT owner.

Currently my R gear feel like does not engage properly.

It has happen a few times after engage the gear, the car does not move after clutch is released.
Can hear some sound of the part moving.

And worse, there is 1 times where the car reverse and the gear seem like shift to "neutral". The car stop moving and come the sound.

Is there any potential problem or just I'm not properly engage the gear?
