this was the fluid that came out? confused me, looked like atf with some additive in it. i am not familiar with this at all....

the car had the 741 center section with 3.91's. not really what i wanted behind a four speed hemi. my rear end guy had a brand new set of chrysler 3.23's for a 489 center, so i found one on ebay for $75, and i bought it. he built it up and that is what resides in the car now. oh, it has the cone style sure grip as well. the diff works great, running regular gear oil my guy suggested back there now, not the pink mystery fluid.
