Problem going into Reverse

My trans has been acting up lately, i dont know wtf.

When i get on it, and try to shift to third, sometimes it doesn't go. Like if i hit a bad RPM ban orsomething, or shift to soon maybe? It just doesn't go SOMETIMES. It goes more often than not...

But lately my car will NOT go into reverse. Sometimes its fine and sometiems its like "nope! not going into reverse" I dissengage and re-engage the clutch, that USUALLY gets it, and sometimes it still doesn't work. Somoene want to tell me wtf? Car has a warranty on it still, but just wondering if this is a problem for anyone else with a T3650. I'd say 1 out of 10 times it will not go into reverse.

EDIT: I also try going from a gear into reverse. Usual response...sometimes it works, sometimes it doesn't.

Hmm i'll look into this. Is the TSB a warranty thing?

Also, when u do warranty work on the car...do u pay ANYTHING?
