What is the reason why the flywheel of the old two-box automatic adaptation gearbox was so loud in 2005?

Fit is divided into two types of transmissions, the old one is CVT continuously variable transmission, and the new one is AT five-speed transmission. I don't know which one you mean. Generally, Honda's transmission has a reverse gear server. It moves in D and R, and there will be a "click" sound when it moves, but it will not be very powerful. If this is the case, it is normal. If the "click" rings more than twice, it may be that the server is too slow to make abnormal noise and needs to repair the transmission. Mainly check whether the valve body and solenoid valve move smoothly.
