Ok I rebuilt a 904 years ago, still have it unused, that when I went to put it in the dang convertor wouldn't fit the pump drive and I was told that this was because the tranny was a lock up convertor trans and that I'd need a lockup convertor for it. Is this what I would need for that?
Early 904 used 17 spline input, 68 and later used like 27, guessing the actual number. This converter will fit any 68 and new 904 but will only work correct in a lock up style transmission. 904 78 and newer, Any A-500. and work as intended.
