Thanks, how were you able to diagnose the transmission?
My knock readings all disappeared when I got the trans rebuilt and the mount replaced
. Up to that point I tried everything. And after the trans was rebuilt, I left the timing alone (21° high gear), 10.4 afr and 25 psi boost and just whacked it. Spun 1st through 3rd, stopped spinning at about 90. Looked and only 0.2 KR. And before that I had been seeing a consistent 1-3° at only 16° high gear timing. It was that point I realized it was the trans slipping and the bad bushing causing my knock. Not saying that’s your problem but. Just my experience.
