Tranny won't shift! (long)

i was driving one day and noticed i had way tooo much play in the shifter....then i pulled the shifter offf and noticed that the bushing that the houses the ball on the shifter is also a bracket type of looking thing.....well that is attached to a rod it was loose on the rod and causing excessive play...make sure that bracket is tight...mine came loose in the tremec and i had to fab a allen wrench to get in the tight area and tightened it....it is much better now. man..i hope you get it all solved out even if it is something else......yeah
