I did have a lot of vibrations the first time I installed the engine. Drove the car like that for 1000 miles, recently pulled the motor to swap head gaskets and increase the clearance around the trans. Now that I’ve made more clearance for the trans I don’t have any vibrations. A piece of the trans sticks inside the trans mount that we needed to hammer. And I believe that’s what was causing vibrations. When installing the engine/trans this time I left all the engine and trans mounts loose. I put a crowbar between the trans and the trans mount that we beat in. Then I tightened the trans mount and moved up to the engine mounts.

That’s good that it is sorted out for you. Maybe the problem is just getting things to sit perfectly. As I stated before, I have no rubbing. The transmission mount was entirely removed and nothing was worse or better because of it. Perhaps this would fix other people’s issues, but if anything was rubbing for me then it would rub all the time, yet my vibrations disappeared at 1400rpms.
I’m not entirely sure what you hammered or what you are referring to when you say a piece of the transmission sticks through the mount. The transmission mount bolts to the transmission with four bolts. The two plates of the mount are joined by soft rubber on either side, and a bolt goes in the center to reduce bounce. They say to move the trans to the side, so maybe you mean that nut going through the hole of the mounting plate hits or something. It is hard to understand. I enlarged the hole, so I could move it to the side more, but again, this seems unlikely to be an issue for me because the problem disappears with rpms.
