I have a 2000 V6 Ford F-150 Super Cab 2 wheel drive. I just started feeling a bad viration during light acceleration. I goes away when I Increase or decrease speed. Has anyone had this problem before? I'm sure its not the engine. I think its the drive shaft or the rear chunk.

 

Where do you feel the vibration?

 

Though the whole truck.

 

I added the Lucas Transmission Stop slipe. The vibration stoped instanly. Appenantly The torque converter was causing the problem. To test that I held the brake and was able to replicate the viration. Thaks Lucas!

 

Was it vibrating only between 45-60 mph or all the time?
