Lockup vs none lockup June 08, 2007, 10:16:22 PM Hey guys i got a lentech aod that i'm puttin in my car that is a non lockup(no small center shaft),my question is can i use my old lockup convertor with it???The billet center shaft in my lentech says it can be used in any aod without changing the convertor so i'm figuring it's ok to use a lockup convertor in a non lockup aod but not the other way around as the non lockup convertor has no provision for small lockup shaft.Anybody know for sure??
