Why does my transmission clunk when I come to a stop?
Customers may also comment that the bump feel or clunk is noticed after the vehicle has come to a complete stop and that it feels as if the vehicle was bumped from behind. This condition may be caused by a slip/stick condition in the interface between the rear propshaft slip yoke and the transmission output shaft splines.
Do you need to downshift your CVT to avoid overheating your brakes?
If you think that brakes are expensive, then–trust me–you would be VERY happy about the costs involved in replacing your transmission. Downshifting a CVT or automatic transmission on a steep downgrade is recommended in order to avoid overheating your brakes. Downshifting these transmissions for stop lights and curves is not recommended.
Why does CVT slip even when the ratio is constant?
Friction drive CVT slips even when staying in a constant ratio. When the pulleys are turning, the belt or chain is going straight. Therefore, part of the pulley would have a different linear velocity than the chain or belt. Since it is constantly slipping, I downshifting would cause extra wear to the transmission.
Why does my car make a clunking noise when I shift gears?
Broken or loose transmission or engine mounts cause the transmission to move… If your transmission mount or engine mount becomes loose or breaks, you may hear clunking noises whenever you make a sudden change in speed or whenever you shift gears, due to the movement of the unsecure mount.

Can a CVT be used on a V6 car?
However, except for that type of situation, you should rely on your brakes, rather than playing with the transmission. There are CVTs on V6 cars these days (see Nissan). My Honda CVT will downshift with the paddle with no shift lever action needed.
