ok im kinda new here so sorry if i mess this up.
but i got an 04 wrx with about 65k miles.
When shifting from 4th to 5th at higher speeds my 5th gear grinds for like a split second and then drops in.
when at lower speeds it drops in perfect with no grind.
i was just wandering if i just change my transmision fluid that it will help the problem? or is it something more?
