Sounds like a driveline issue. A clicking noise that can be felt, maybe the U joints? Just rolling off the line, no noise or vibrations, maybe around 3 mph its noticeable and gets worse with speed (I kept it under 5 mph and only drove it maybe a few hundred feet)

here's a pic of the old mount next to the new one



here's a pic with the mount installed, floor jack underneath the oil pan because I'm changing the motor mounts too, the driver side mount is totally shot.



I checked the manufacturers site to verify the part numbers are correct and the guy at napa didn't give me the wrong mounts, but everything checks out.

any ideas?

 

to clarify, right after i installed the transmission mount, i did a short test drive to see if all was in order. that's when i discovered the noise. i went ahead with the motor mounts to see if the driver side mount moved and caused the issue in the back.

 

anybody?
