torque converter shutter or axle wrap

[john6200]

Problem solved!

I took powerboatr's tip and I zip tied a webcam underneath my truck so I could see what the rear diff was doing when I was driving. differently axle wrap, the drive shaft flange on the rear diff gets at least 2 inches closer to the bed when I go from dead stop at about half throttle. you can watch the diff return to it normal position at the same rate at the shudder decreases. I am buying a set of bolt on One Up Off Road traction bars and thank you everyone for the help.

Glad you finally convinced yourself on the axle wrap. Nice job!

Glad to see you've solved the issue, and that I was wrong warranty issues are a far bigger headache than they are worth often should it have been a transmission problem.
