Ok, now I'm still confused.
We have a 2000 half ton Chevy Astro with G80 (semi floater) and we had rear end clutch chatter in that vehicle because the rear diff fluid was changed without the additive. I was told by my Chevy tech friend that the Astro G80 needed the additive and he then added it and over the past couple years the chatter has been getting better with the additive.
So if the 3/4 ton full floater G80 has clutches, why wouldn't we need the additive?
Thanks
