So my new engine is in, and I have driven about 400 miles today, towing near the max tow limit. Whenever I am accelerating in 3rd or 4th gear, there is a shuddering vibration throughout the van. Whenever I am at 65 miles per hour with such light throttle that there is no pressure on the drive shaft, there is a lighter vibration, almost as if I had a bad u-joint.

Apparently, my old engine was on his last legs the entire time I've owned this van. The power levels from this new engine are incredible. Is it possible that I am experiencing some form of glazing on the torque converter due to the old engine's lack of torque, and is there any easy way to get rid of it while I am on the road?
