Can this cause clutch wear?

Can a sticky 1-2 valve cause the 1-2 clutch band to wear out? If/so, how do I tell if its completely gone, or just a little worn?

a worn band is basically a dead band, you can shim the servo pin, but is pretty much a band-aid and can make it worse if you don't get it right on.

Thanks Mark. Does it mean that my band is worn if there is black soot on the bottom of my pan? Also, is there a difference between the BQ governor and a BRF governor?
