I bought a CM 3 clutch with about 30,000 on it. I replaced the TO bearing and had the tranny put back in. Anything under load and the trans wont go in to gear. Normal driving is fine, no grinding. There is no grindig under load either, but it just wont go in to gear with out trying a few times. This didnt happen with the stock clutch. The guy that did the work said Mitsu told him to put in gear oil. I think I have 80w-90 in there right now. Would this make the shifting harder?
