Hey guys, I am currently swapping my engine. I have an 07 Maxima and I'm swapping in an 08 engine. Both vehicles were CVT transmission and when mating my trans to the new engine my flywheel (ring gear) is binding . If I loosen the transmission it frees up again. I have removed and replaced the trans 3 times and everything is fine up until the point when I tighten the bolts again. I even swapped my original flywheel in and still the same issue. I saw this same problem on a different site but there was no answers or replies of what may be causing this. Please help. Loosing my mind here.
