<VV> LOW speed shake?

[N2VZD at aol.com]

Still there after replacing trans and converter?  Do you have  "friends" 
who could have added a truck weight to a wheel?  or bent wheel?  or bent axle? 
Does it feel like one corner of the car?
Of course I am sure you have checked all the obvious? 
Last crazy powerglide I fixed was a  converter outer turbine  shaft in 
backwards..I always wondered how that was accomplished. Had to go  together 
hard.(It was a driveway job).It moved , but no power and shook.
Any noises related?
