I guess all I can say is ..... BACKYARD MECHANIC AT ITS FINEST? Roads too high causing your header to crack twice and your oil pan 3 times? I would have raised the car up after the first time you killed it. Or made a skid plate or something. You have to ask yourself on your last tranny build.....was it right from the get go....or am I an ass on my trannies? Sounds like to me that the bearings were reused and already wornout on the second tranny build. Either way....um..good luck.
