I used Z1 last time around, but I see it has been replaced by DW-1. Should I just do the standard 3 quart drain with DW1? OR any other fluids that would work for smoother shifts.
DW-1 works great in the older Honda transmissions. I use it in our '05 MDX and our '08 CR-V. I've used various aftermarket offerings as well, and prefer the DW-1.
