The Red or The Black Bottle?

[buddy-lee]

I have a couple of Chrysler vehicles which use ATF+3 (the highly friction modified fluid)and a 98 Volvo S70 just purchased ,both of to which i would like to add Lubegard for transmission additive. On the Volvo which uses Dexron III, it seems like a straightforward choice to put in the red bottle but in the Chryslers, do i add the black friction modifier transmission supplement to already friction modified fluid or the red supplement to the ATF+3?
I don't want to fry the Chrysler trannies with the wrong fluid choice...any experts on Lubegard?

It seems you could use the Lubegard Platinum (http://lubegard.com/automotive/trans_atf_platinum.html) but try contacting them first.

If using OEM-spec fluid stick with the red or platinum.
