God man!!! YES!!!!! But DONT use after market fluid! Use Honda stuff! It will make a difference! (from what Ive read)

If you have any signs of hesitations or shudder, or anything related to symptoms of clogging tranny, then absolutely. Most of us who have done this, have noticed immediate improvement or resolution to previous issues. Mine had a shudder at 60kph, or 40 mph. After the fluid/filter change, it was gone! One of the best 3h (done slowly by a newbie) DIY.

I noticed a HUGE improvement by NOT using honda Z1. I have been using Redline D4 ATF for close to 10k miles now, and its shifts so much better than it did with fresh Z1 in it. It also hasn't even started turning brown yet, like Z1 does after a out 5k. I haven't had a single problem since I started using D4.
Im not ragging on anyone that says Z1 is the only way to go, but I have tried really hard to find someone online or in person that's had any problem with their trans because they used something other than Z1.
There is a 24 page (and counting) thread here on acurazine in the Third Gen TL section devoted to owners switching to Redline atf and LOVING it. Not a single negative post that I can find. Although its not the same transmission we have, its still proof that Z1 is NOT the only way to go.

I use D4 and it made a great improvement it the "cleanliness" of my cars shifting. It also sounds better at low speeds; much less tranny whine. And the fact that it stays clean so much longer...I am sold.

Happy Draining!

i also agree... i used to be full blown Z1 fluid only, but have seen the light... i have switched to Amsoil and will be moving to Redline eventually as I can't source Amsoil locally anymore... the tranny shifts much tighter... down with Z1!!!

I am interested to see which seems better in our cars; redline or amsoil.
