Personally I dont know much about using specific fluids. From what I've seen its best to use Honda ATF in all honda transmissions. Honda uses a special lubricant for its parts where-as many other ATF fluids do not have the same lubrcants and in some cases they contain dangerous solvents.

I had a rough shift problem and used Honda ATF+ Lucas Transmission Fluid Treatment and it worked like a charm. It's not going to fix everything, but the shifting is 60% better if not more. Lucas ATF treatment is more like a transmission syrup rather than a fluid. Its designed to thicken the fluid but not change its checmical composition.

I'm not sure if anyone has experience with this additive, but ive found that it works great and it hasnt done any damage to the automatic tranny.

Get back to me with any comments.
