I started another thread since my scenario seems a bit different then what I've been reading thus far about shuddering or vibration..

My truck has a vibration after shifting to 3rd gear, at around 25mph and continues up to 35mph, but haven't gone any faster then that yet!

This was a running motor that sat for several years, I dis-assembled, checked everything out an reassembled and it started up on first try...the flywheel had been re-surfaced with new pressure plate and disc with a mark for alignment...
but I do not know for certain if it was the exact flywheel that had come off the motor, so that is an unknown as far as it being balanced...

There is nothing at idle, or up at higher rpms, no knocks from engine, and other gears have no issues...the motor mounts are stock and correctly set, so I am asking if it is possibly the universal, or what else to consider???

I do realize that the unknown flywheel is a major consideration, but would like to know if there is anything else to consider if by chance the flywheel was properly balanced with the crank...

Would like to keep this motor running while another is being rebuilt...

Suggestions, advice appreciated....
