So I was driving today, and when going into 3rd at higher speeds it grinds. Sort of like going into reverse, like its not synchronized. At low speeds it doesn't happen.
Higher speeds meaning high RPMs? If so, tranny is in need of a rebuild (or at least third gear). Typical T5... Third gear is normally the first to go IIRC.
Which would be better? Rebuild using the better parts, or the tremec? Also, which tremec model to people usually use? Like I said, I don't plan on doing much more that H/C/I in the future..
