This thread on 8th Gen Civic forum claims to be safe as the warning against Honda flushes is directed towards pump assisted flushing. I would like you guys to weigh in. The concept is to open up the return line and fill in the proper amount via the dipstick as you drain from the return line. The hazard is obviously that draining too much before you fill and things get dicey...
If one is careful, is this a valid practice or are there other failure modalities not considered by the procedure?
8thCivic No pump full ATF change in one go.
IF I go this route, fluid choice is up for grabs. If I do conventional drain fill, I will likely go DW-1 out of the hope that if this were an issue for the other millions of Honda users, it would be in the news..."OEM fluid killed my transmission!"
