Great info Spike! As you can see from my build info below I have a PTC converter. At lower acceleration the transmission is a bit more squirley and seems to hunt. When you go hard throttle it is very crisp. I understand that the stock converter is a bit looser and is designed for smoother shifts. My question is should I be experiencing what I am with this higher performance converter. I honestly don't know what the stall is (long story that I will share later) but I believe it is a 10" Lock up. It's almost like it wants to shift and then stalls a bit. Help a rookie out brother!
It was fun while it lasted.....
