My 4th gear seems to be notchier than all of the others. I can feel a notch in it every time I shift below say 6k...

Does anyone else experience this with their tranny? My 1,2,3,5 are very smooth.

On my g/f's si tranny, her notchy gear is 2nd, and her 4th is the smoothest.

maybe I'm slightly low on tranny fluid. I have a tiny leak..
