Yeah did you take anything apart before this started to happen?oooooh ho hooo ho hoooo...
oh that sucks... RShackleford might just be right... it probably isn't a gear that you need though. i'm not really experienced in this field.
Was there an event that preceded this problem?
I don't quite understand what to look for here. Do I need to start pulling the plastics and cover off? Where is the spline?If the spline shaft coming out of the tranny takes a hit it will jump off the shift star....there is a really thin piece of metal holding it in place. See if there is play in the upper heim (in or out) on the spline.
