I have the Trans-go TF-3 instructions Dave. It shows a cup plug that's driven into the case to block the governor. It's under where the valve body bolts to the case. PM me your e-mail address and I can e-mail them to you
BTW: as I mentioned these are the Trans-go TF-3 manual shift instructions. If that's what valve body your trans had this should help you. If yours had an aftermarket manual valve body it may not use the same method to disable the governor.
