04 Acura TSX- which ATF?

[Dohc98vteC]

I used Z1 last time around, but I see it has been replaced by DW-1.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.

DW1 is the correct fluid that supercedes the old Z1, I would go with DW1 if it's possible.

Maxlife dex/merc is an aftermarket choice if you want to go that route.

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.

DW1 skip the Z1. I would do 3 drain fills which is considered a flush on a Honda.

DW-1 just drain/replace drive on. 3x if you are nervous but a lot of coin to throw away IMHO.

DW1 or Maxlife. Just make sure you change it frequently...

Any full synth universal multivehicle ATF that mentions either spec can be used.

Do a drain/refill. If you are happy with the shift quality, you can do a couple more in the future. If not, try another fluid.

Amsoil Redline Amalie Royalpurple BG Wynns Lubegard...are some more options.
