99 grand prix gtp in drive but won't move.
When my car comes to a complete stop and then I try to go again I get the
RPMs but the car won't budge. Eventually I can finesse it to start going and all
the other gears catch fine until I stop again. My transmission doesn't slip and
my reverse also works.
I had a guy who doesn't know much about transmissions look at it and he
thinks I need a new tranny but i think I had this problem before and a new
throttle idle or something fixed it. I don't know much about cars but does that
sounds logical?
