Just an FYI more than anything, but I changed the the tranny filter on my 03 4cyl and drained and filled with 3 qts of the new Honda fluid and it seems to shift smoother and less slushy from gear to gear.

Thanks Redbull for the filter part number, when I asked my Honda parts guy, he looked at me crosseyed until I gave him the pt# and said "yup, you're right"

About 50 bucks for the filter and fluid, but alot cheaper than a new tranny...

 

No problem. Sounds good.

On my 8th generation, there looks to be more things in the way of the rear clamp on the filter. I haven't change my filter yet though. Looks like I might need to use long reach hose clamp pliers if I decide to change it.

I have to say though, on my Accord, it always shifted smoother after a ATF fluid change. It was even smoother after I used DW-1 when was it was first introduced, compared to Z1.
