Best brand of ATF and why ?

Want to shout the old 92 terrano auto a birthday - change
the fluid and filter.

Have you got a way of flushing out the fluid from torque converter etc? I understood that simply draining it gets only some of fluid out and it needs flushing.

Your best bet is to go to an auto transmission shop and ask them to do it.

Brand is largely irrelevant, it is the type that is important.

Doing backyard approach - trans shop charge slightly less than vehicle worth. Mechanic said to me better to change often and bulk of it
than not at all, granted do not get the lot out but do it often enough and
pretty much ends up that way.

I know the correct grade to use - like the shell products,
castrol these days seems crap.

I did, with the approval of our friendly mechanic, what I call an "exchange transfusion" on our Accord V6's auto transmission: drained out 2.9 litres (all that will drain of the 7.2 L that it holds) and added 2.9 litres of fresh fluid. I did this 3 times over a few hundred kms. Probably cheaper than getting it completely drained and refilled by a garage and the resulting fluid would contain very little, if any, of the original. Hint: buy the fluid when they have a sale!

Good to hear - cheers

A few years back my son took his A32 Cefiro to a place over Wigram way. The place was/is called CV specialists. A full auto trans flush (not just a drain and fill) cost $179. Have a look here http://www.cvspecialists.co.nz/auto-servicing/automatic-transmission-flush

Not quite. After one change, the oil will be 66% old. After two changes, about 50% old. After 3, about 35% old, plus the earlier "new" oil now has some miles on it.

You need to flush it, which is what a good auto shop can do.

Cheers very much for that link - looks the berries - cheap too

I thought that you could only use genuine Honda Auto Trans Fluid in a Honda car. This fluid is only available from the Honda agents and never on special.
Any other brand of fluid will destroy your auto trans, I believe.

franc123, Dec 10, 9:43pm
That is what they want you to believe, but in reality other brands are made to the correct spec, Castrol and Fuchs are just two I can think of right now that make fluid that can be used. The key is not to let an uneducated Muppet near it who will use a dexron 3, and only dexron 3 spec oil in it. It goes without saying that anything under warranty still should have genuine fluid used.

Honda don't make oil. they buy it in a big drum and just stick their name on it.

You can flush out the convertor etc yourself, drain the fluid and do the filter, fill it back up with correct amount of trams fluid. Disconnect the rubber house that goes from the cooler back to the trains. Extend that bit of hose or pipe if need be to is can reach a suitable sized container so you can see it. 4 litre at least.

Hold that pipe in the container, get someone to start the engine, have them at the key ready to turn it off when you yell. Watch the fluid j out of the pipe. It will be dirty to start with. Rather than run the engine for a period, the fluid will come out fast and under pressure, probably better to get the key person to start it, let it run for a few seconds, then turn off, repeat a few times and then When you start seeing bright red clean fluid you have finished flushing. Turn engine off, reconnect the return line. Top the trams back up again. The check the fluid level as per manufactor most state hot, in park on level ground. Just make sure when flushing it that you know how much fluid the trains takes and don't let it run empty.

It's no harder than bleeding brakes really. No need to go to a shop if you have basic mechanical skills.

as per 13 that is exactly how its correctly done . anything else is cowboy moron doing.
you also have to do the work inside the pan like tighten bands if the service requires this. i done bands on a 1998 capella mazda automatic so they do have this its just morons whom dont know the correct procedure whom skip these things and wonder why the trans is crapping it self
Also if its got problems then you could accelerate the death of the trans by servicing it , its why morons say you dont service it it ruins the thing. it dont if the clutches are goners and the debrie floating is the only thing making the discs grab then flushing and servicing it will make the disk propperly slip the trans was rooted befor you even serviced it in reality of this case .

franc123, Dec 11, 9:06am
The funny thing is that so many people panic and ask for a trans flush at the first SIGN of a problem with its behaviour, when in reality it should be either done at the correct interval or else the first SNIFF of a problem, either in the form of slightly discoloured or smelly fluid. The latter can be a more of a problem for those who don't have dipsticks and can't easily monitor its deterioration, but it still should be looked at during normal service.

2get1, Dec 11, 9:13am
Other thing I forgot to mention, make sure you get enough fluid to flush the convertor and lines. Easily another 4 litres plus. So if the repco book says it takes 6 litres of fluid, then get atleast 10 as the amount in the book doesn't usually include convertor. Better to over cater , specially if it's your only car. Nothing worse than getting half way through a job, car no longer drive able and you find you doesn't have enough fluid to,drive it safely without risking damage. I would to be on the safe side allow 4 litres for the convertor and another couple to flush the lines and allow a bit of mixing as the old and new mixes together.

franc123, Dec 11, 11:00am
20L pack from BNT or whoever is the way to go, the per litre cost from Repco or Supercrap for 3, 4 or 5 4L packs is sky high in comparison, especially at normal retail. If you can get the fluid running clean after using 10L (possible in smaller boxes) then you have enough to do it again later on.

woodypc, Dec 11, 2:49pm
Yep, this is how I do it too, but I also cycle through the gears as well to get all the old oil out.

Why does Castrol seem crap? Best out there in my opinion.

tony9, Jul 2, 9:22pm
Agree completely. But the OP's question did not give me confidence that he had the nonce to do this.
