I have recently rebuilt my 292 with a FordOMatic behind it.  Transmission has new gaskets. After starting my motor; I have a knock at low rpms.  It goes away at high rpms.  Sounds like a rod knock, but I was told that it is transmission related.  After pulling the pan off the motor; I tend to believe that.  Have pulled transmission back out and have replaced the torque converter and fly wheel.  Still  have the problem.  Has anyone had this  problem??  Need help.  you can call at 616-891-1673 or 616-299-0153.  Trying to get back on the road.  Thanks for any help.  I will be checking this forum for responses.
