What was wrong with the previous transmission?

Still have the old flywheel, pressure plate, etc? Iíd suggest throwing those in first assuming those are ok.

My second gear blew out, you could shift into second and itíd just rev like it was in neutral. Interestingly enough on jack stands the wheels would turn in second. Both transmissions have been pretty tight for the last .5Ē of install.

Iíve got those still, my flywheel had a good bit of play in it, pressure plate was ok I think. The sac system is whatís kept me from pulling the clutch out.

Itís gonna be a week or two before I can stomach pulling the trans out again. I need to get out to the mtns and blow off some steam.

I really appreciate you guys brainstorming with me on this. Itís been a very expensive, blood sweat and nearly tears 5 months of ownership. These cars are unbelievably rewarding to drive so Iím hanging in there.

Is everyone here running the transmission vibration damper? Iím planning to put it back it but was curious if that might be increasing my situation

If you mean #7 here, yes, haven't tried running without it, and it could help you.

Appreciate all your help mr gizmo, if you make it out to the Rockies hit me up and Iíll let you drive my car on some of my favorite roads

I enlarged the bracket holes so I can rotate the bracket and remove any lateral pressure. Does this look sound? Also thinking about ditching the rear bolt

Nice. You are doing some custom fabrication there, lol. How did yours get bent in the first place?

I installed it with the bushing slightly offset. I think the shift rod allows for some kink but I figured I should try to straighten it out before pulling the flywheel.

One of my good buddyís suggested the pilot bearing. Iím gonna tackle it this season. Not thrilled to deal with the SAC, is there anything to gain with a different pressure plate?

Highly doubt it's the pilot bearing. But good luck. Seriously. I helped a friend reset the SAC. I forgot how we did it lol. Wasn't too hard though iirc.

In the past week Iíve had a whine develop. It goes away when the clutch is pressed in and is present when the the car is under load and/or the clutch pedal is out. I think that means the pilot bearing has gone out. Anything else I should have on hand when I pull the transmission out?
