I have this, I think, but in my case it is right around 40mph. It's like a harmonic distortion/low rumble and what you describe with giving it a bit more gas alleviates it - though if the speed limit is 40mph that is not much of a solution ha!

I suppose the same suggestions apply, even though I don't have a 700r4 but a TH350 (with 2 piece drive shaft) ? I wished I had a 700r4!
