The only thing I can inform you on here is the Lucas Slip-Fix additive. I used it on both my Camaro and my Mustang...only 1/2 bottle each though. It made a noticeable difference in the shift firmness. I have an AOD tranny too, it's still stock currently, and for a good couple of days the Slip Fix completely stopped the slippage into second. But it started up again. The line pressure is too high and the tranny is just too worn for an additive to do much good. But it does seem to be good stuff. VERY thick.
