MTB rear derailleur shifting problem

Hi,

I have a mountain bike which shifts gear smoothly, but the rear derailleur
drops the chain back down to the small cog from all other cogs unless I keep
the shifter in place with my thumb, an obvious inconvenience. I can remove
it from its handlebar mount, but the mechanism itself appears to be
contained, un-dismantlable.

The stops within the grip shift are worn out. I did three of them
(Right, Left, Right) on a HUFFY KMART Powerline 21. The first
replacements pair cost 10 for one or 15 for pair and 5 shipping. For
the second replacement went to LBS and cheapest was 25 for one. Both
from same manufacturer, SRAM.
