Before I replaced the bushing, I tested the bolts and sure as heck... they were loose from when I did the torque converter. I tightened them up, and the tranny don’t move no more.
Noise is still present. I am really wondering it’s the pinion depth, but I don’t know. The rear end is fairly fresh. I think it has less than 25,000 miles on it.
