checked fan, motor mounts, tranny mount, harmonic dampner, all were tight and in right position. pulled inspection cover for torque converter, didn't see anything floating around in there, bolts were tight on TQ. good thing I went down there though, found a little oil dripping out of an oil pan bolt, and found them all to be rattled loose to about a 1/4 turn passed hand tight! yikes! tightened them back up. fired her up, vibration was gone, Torque converter must have just been a little hot is all I can gather. Any other points I should check?
