vibration problems

[Paul]

Have 69 roadrunner, 4 speed 383 car with dana rear end. When im in the throttle its smooth as silk, when i let out of throttle its smooth as silk, its when i get in the middle with no tension, i get a good vibration. Give it throttle and it quits. Trans, rear end, and pinion angle all good. new u joints. Any advice???

where do you feel the vibration the most? your butt or hands or foot?

What transmission do you have. Auto or manual.

Feels like back of transmission but had it checked and checked out good.

Do you feel it in the shifter and is it in all gears?

 

[Paul]

Feels more like the drive train near the transmission. But what’s crazy you can get into the throttle and it goes away. Let out just alittle and starts again. Pretty good vibration.

Sounds like an internal transmission issue to me.
