I plan to just buy a new cooler and flush out the lines. The converter is on it's way back to the manufacturer ( ACC ) to be rebuilt or replaced. I know the 727 is an easy trans to build I have built 4 of them. But with the motor I have in this car I wanted a pro to build it so everything was perfect kind of funny huh. I will call the TC company and see if he still wants to warranty it after I tell him what we found in the trans.
