MitsuStyle - View Single Post - Grind going into 3rd gear .. Need Oil recommendation

Well the tranny needs rebuilding as it has a slight grind going into 3rd (only at high rpms). I have a blend of Redline MT-90 and MTL in there now. I want to go racing this coming weekend and get one more race day out of it before tearing it apart to rebuild.

Because of the grind, would I be best to run just a straight synchromesh like Pennzoil or run a blend of 2 to 1, Pennzoil Synchromesh and a quart of Heavy Shockproof?

I'm wondering if Shockproof would help it or make it worse. I have 1 quart of it left.

I believe the grind is a result of numerous No Lift To Shifts. I also missed 3rd once and ground it some.

Thanks.
