My  question is, could overfilling the transmission cause a low end  "knock".



Jedd,
May I suggest that you get a few Corvair people to listen to your knock.  
Because there are knocks and then there are other knocks. And what is a low-end  
knock? low end of the rpm range? or low end of the engine? So what is 
knocking?  Is it metallic like a con rod? Or is it more likely just detonation (bad 
spark  knock)?
 
If it is detonation, then first thing to check is the modulator. If that  
leaks trans fluid into the engine, it will detonate. So check or replace the  
modulator first. And please don't tear into the engine or tranny until you've  
got a pretty good idea of the cause.
Regards,
Bob Helt
