Under hard acceleration in sprot mode you may experience hard shifts.
Are you sure it is the transmission that is clunking? It could be the u-joints on the drive shaft that are making the noise. When the u-joints on the drive shaft are bad, there is an audble clunk when you accelerate and when slowing down (basically the same motions you go through when shifting gears).
There may be a problem inside the transmission, or the linkage could be loose or disconnected in some way.
It could be as simple as a slight imperfection in one of the gears or it could be an indication that the drive shaft or "half shaft" is worn.
It's probably the transmission, either the valve body or the clutch pack. Either way, it means a rebuild of the transmission.

In the Model T transmission, each of the gears does the same work. The clutch is only used during a direct drive. The Triple gears are used to drive in low gear and reverse.
Yes there is, otherwise it would not be able to drive. The transmission is the gears, the chain and the sprocket. Some motorcycles have a drive shaft instead of a chain.
I think what your talking about is you final drive gears. They are in your differential. You also have a gears in your transmission.
Your forward gears are out in your transmission I recommend you take it to a shop.
Transmission gears? In the transmission.
Mainly because the C6 transmission only has 3 gears and no overdrive.
