My cuda used to kill a "super" sprag every 100 runs or so. Went to a mechanical diode and no more problems.
Last converter I had done we went spragless. Used to be that the spragless converters would slip a lot up top, but that doesn't seem to be the case anymore.
We were chasing an issue with the car a few years ago. Inconsistent ET's and reaction times. Lost MPH etc..... We changed ignitions, fuel pumps etc..... Finally we started to look at the symptoms of a failing sprag in the converter. Called Transmission specialties and discussed it with them. They convinced me to buy one of there super 8 9" spragless converters........One of the best purchases I have ever made! ET, MPH, Consistency all came back!
