couple weeks ago had the pan down and saw converter material in there. buddy of mine is a mechanic said it was only a matter of time. well here i am now with no lockup. The whole trans built by hts had a suncoast triple disc converter, it only has 54 thousand miles on it but its from 2007. I know i dont abuse this truck nothing has ever broke and 67 thousand miles on the all terrain tires that I just changed. correct me if I am wrong but shouldnt the converter lasted longer than that? Its not at the strip on the weekends or the sled pulls. dynoed 710 hp.
