Hopefully someone in here can address this issue, I have also posted it in the ITR forum.

Car- 00 ITR, stock trans just ACT clutch

The trans will sometimes go into 5th, but not usually; and reverse seems like it doesn't exist anymore. The trans did start making a rattling noise sounding like a throwout bearing kind of, but I'm also thinking the shifter was placed in between reverse and 5th and someone pushed it up or down and bent something; my question is - what could be bent if so?

 

There is nothing specific to the ITR about it. Just ask in the tranny forum.
