Changing AT fluid in '95 Accord

[Gebo]

I've always had Toyota's but my daughter had to have an Accord

. Anyways, I am currently running AutoRx and am gonna flush it and replace fluid with Honda Z1. How would you flush it? I have read several posts and am sort of confused

. It seems you disconnect a hose from the radiator, run it until the fluid slows down and gets bubbly. Then you add 4 qts through the dipstick and run some more, etc. What's preventing the old fluid from mixing with the new fluid?

I'm having a terrible time trying to find a funnel that will fit either "in" or "over" the dipstick tube

I only bought 12 qts of ATF fluid. Will that be enough?

2 gallons for flush and 3rd for topoff-- 12 quarts should be close enough.

The fluid mixes in the TC. Since you've pumped the sump dry, fresh fluid will force old fluid out of the TC, through the cooler, into your bucket. Mixing is a side effect and is why you use 2-4 gallons to flush it out. Since nonsynth fluid is cheap, I would lean toward more ATF and buy the extra gallon. If synth ATF if being used, 12 will suffice.

This mixing occurs regardless of machine or method. The only solution/prevention for TC mixing is a TC drainplug which most cars don't have and not worth the hassle to install.

Funnels from pepboys/autozone around here fit almost any dipstick tube that exists. Keep looking.

Don't laugh, but is there an easy way (logical) to determine which of the AT lines is the "incoming" and which is the "outgoing?" It seemed both of mine are going into the top of the transmission.???

Logic would make me think the return would go into the top and the outgoing line would be near the bottom.

Trial and error is the easiest method.

To find the direction of flow, disable the engine (remove coil wire, etc.), disconnect one transmission cooling line, crank the engine, watch the flow direction.

Does your Honda have a fill plug on the transmission housing? If it has the really skinny dipstick tube, look for a fill plug.

I drain the sump if there's a drain plug (I think the Honda does), and refill the sump. Then I connect a short hose to the cooling line and pump one quart (from a small system) or two quarts (from a large system) into a jug. Shut the engine off, refill the amount pumped out, pump out another one or two quarts, stop, refill, etc., etc. Yes, there's some mixing of old and new ATF...can't be helped. Some folks overfill the transmission before pumping out...seems to work for them.

Doesn't that year Honda call for Dexron II ATF? I'd use any good Dexron III ATF, with Schaeffer #204S synthetic blend being my favorite for long life and moderate cost.

*******AAHHH, maybe that's why I can't find a funnel that will fit. It is super small in diameter.

*******Honda did one of those AT fluid updates sort of like Toyota did when they changed the recommendation of "some" vehicles by going to type T-IV. Honda's updated ATF is the Z1 for "most" applications.
