It depends, Transmission Specialities should be able to tighten it up some, since its a 10inch. They make really good converters. I don't think its broke or that anything is wrong, otherthan you just have a 4000 stall converter, not a 3000 stall. Me personally I think 4000 on the street is to much. You either need a lower stall or your going to have to run slicks 24-7.
