Again, it all depends on how the shop operates, but I would definitely ask first, then ask to watch because you are interested. Most shops are okay with it.

 

I personally would use either Honda ATF Z-1 or a multi-vehicle ATF such as Valvoline Mercon V or Amsoil Universal....note: Valvoline Mercon V does have the necessary FMs for a Honda ATF Z-1 app...I verified it with Valvoline....just look on the back label.

There really isn't a need for a flush...just drain/refill periodically and that's all you'll ever need. ATF doesn't really need to be changed out completely....a periodic refreshment of the additive pack thru a 1/3 drain/refill is enough.

I guess if you really did want to purge the system, you can simply unhook the return line from the transmission and allow the pump to empty itself by starting the car and allowing to idle in park. There won't be a problem with sucking in air if you turn it off immediately after the fluid (coming out) slows to a trickle as long as you refill the transmission immediately afterwards. Neither will the moving parts inside the transmission have a problem...the residual oil film coating the moving parts will be enough to allow it to stay lubricated during the few seconds it is being run on low fluid...after all, there aren't that many parts moving within a transmission when its in park/idle.

 

i am about to do a ATF fluid change and came across your method and looks very interesting. did anyone tried it? do you think honda dealer change the atf fluid this way too? btw; i had a tough time locating the drain bolt, does anyone know if the drain bolt is facing front or rear, right or left? my 5th generation accord is facing the wheel at passanger side and pretty easy to change.

thanks

 

Wow, what an old thread. Anyway, I wrote that back in the day when I didn't know any better.

I think you're better off just grabbing Z1 from the dealership and doing a single drain and refill, and then refilling. That's really all you need...if you want to be perfect, drive around and repeat it three times. I've learned that hunting down the lines and fussing with the mess just isn't worth it.

 

thanks for your reply!!!

where can i spot this drain bolt? is this bolt face front or rear, or toward wheel like 5G accord does?

thanks

 

Don't know, look for a 3/8" drive bolt...and its on tight...so use a breaker bar or 1/2" drive ratchet w/3/8" adapter.
