So I'm having this vibration on my UCF20 while driving 45-55 mph. I shift to neutral and put it back to drive and it goes away but when I stop and raise speed again to 45-55 vibration starts again feels like its coming from below the center console. Any ideas on what it might be?

 

trans mount and/or driveshaft carrier bearing.

please search.

 

As well the motor mounts. My tranny mount came out in two pieces. Still have a slight vibration but not nearly as bad as prior to the new mount being installed.

 

I did search, thanx for your suggestion though

 

thanx mike will take to my meachanic for final diagnosis.

 

that was the driveshaft,good luck like + this for the shaft
