I believe it would depend upon whether the A/T had its fluid changed at or near the recommended intervals. Using the Ford fluid will "scour" the system and might result in the loosening of quite a bit deposits which theoretically could create problems. My recommendation would be to initially just drain/refill 3x with about 50 highway miles in between. Each time, visually inspect the amt of particulate deposited on the drain bolt. Run the vehicle for a few months, then drain and inspect the bolt. You might at that time decide to use the Ford fluid followed by the Honda. The other consideration is the condition of the radiator. If this were my vehicle before I would try the Ford fluid procedure I would install a new radiator as who knows how much "crud" is deposited in the old radiator's section of the A/T cooler which could be loosened and run into the system as the result of using the Ford fluid.

I have 92k on my car right now, so you recommand I skip the step with the F-type fuild? So I should just do the 2 drain and fill with the dextron fluid and 1 drain and fill with Honda ATF.

Also I'm wondering, would the 4x tranny flush work with other honda vehicles? Would it work on a 98 Civic? Thanks!

First, let me state that I am not a transmssion specialist. The procedure by Gil was posted by a specialist. I don't remember a response by him re this specific question. All I am saying is that if there is a large amt of particulate deposits accumulated which as a result of being loosened by the Ford A/T fluid enter the system, you could be in for blockages. Likelihood unknown, but something to be considered. I would not wish someone to try this on an A/T which has 80,000+ miles (and never been serviced) and then have the member report back that the A/T has now "bought the farm". Caution is the watchword.

Forget the Dexron. The point is to drain out the old and replenish. Only use the Dexron if you use SmartBlend. My recommendation is 12qts of Honda A/T fluid (3.5 x 3) purchased at your local Honda dealer. This is the easiest route. Perform the 3x drain/refill. You may be pleasantly surprised I was.
