The only thing I can think of is the lockup is so tight because of one piece shaft is that it’s just picking it all the vibration up.

I’m gonna drop a demon 2 piece shaft in it to test our soon.

And then after if that doesn’t work I’m swapping the lockout kit for a newer style kit and going with new upper and lower control arms.

It’s the last thing to button up my car. She runs so good right now. On 20” street tires the other day I ran 9.98 at 142 with a 1.73 60’

That’s me literally driving it from work and messing around all day to going straight to the track with pump e85 and running 26psi on my street tires.

Yea could be part of the issue. I really can’t remember if mine was there prior to my rear control arms or not. All my vibrations go away under WOT or when getting on it more than part throttle.

Correct the vibrations are under WOT or just part throttle

By lock up do you mean converter clutch?

I replaced my trans mount today. I'm pretty sure it solved it, but I need to do some more same speeds tests.
