This is getting old. Vibration/Shudder

Hello,
I have been trying to figure this vibration/shudder out for forever with no luck. I am getting a major shudder felt in the steering wheel/gas pedal and just in the car in general. It happens when the below are present

- 30-40 MPH (1500-1800) RPMS
- 3 or 4th gear

I have balanced the driveshaft changed out U joints and recently had the torque converter replaced. I also had the trans rebuilt.

What am I missing I'm tired of pouring money into this thing. The shudder happens when the gas pedal is pressed only, when I let off it stops????

Any help would be appreciated.

-Matt

i know its not U-joints, tires, or rotors. My power steering fluid looks good. I have no idea what it could be. Considering I just had TQ and trans rebuilt and it only happens when accelerating/pressing the gas pedal.

Is it more of a side to side shudder or front to back?

I may be a little off here, but it sounds to me like your complaining about an engine problem. Is the engine misfiring causing the shudder?

I thought about this, but i'm not sure exactly how to diagnose a misfire. I was thinking it may be injector related, but I'm not pulling any codes and have no smoke. I have felt like my truck has been underpowered lately and was going to make a post next about that lol.

What should I be looking for in a misfire?

after a little research I think it might be the UVCH. It seems to be a problem with these trucks as it comes unplugged under the valve covers. Welp I know what im doing all day. I will check the ohms first tho to see which side it is.
