What is this vibration you guys are talking about?

 

The vibration I am talking about is when my truck shifts into high gear (od) I think it is either transmission or converter, been like that since new.
A example is when the truck pulls in every gear up to 3100 rpm's it will shift, the chatter or vibration is when it shifts into high gear only. The vibration, chatter also shows up when I am cruising along at say 70 mph and drop my lead foot into the go pedal it will vibrate until the trucks rpm's come above say 2800rpms. Don't know what it is for sure but my best guess its the converter, second guess its the trans , but most likely the converter.

 

Florida, you should fill out your sig so we know what kind/year truck you have.

 

Will do trik3961, finished sig!
