C5 Aisin Warner 6 speed automatic

Very interesting I was just today quoted $360 per container? $1000 plus for full refill by dealer for our 2010 c5 2litre deisile and they were incredulous that I thought that it needed changing at 75k km
so I am no more the wiser
 
There are online ads from the US for Aisin Type 4 for $5 per US quart.
 
Given that it's the same slushbox used in a huge number of vehicles from around the world, I can't see why you can't use any automatic fluid rated AW-1 (e.g. from your local Toyota dealer)...
 
Inspired by you guys, I'm gonna have a go at a fluid change on my wife's Mondeo with the same box. It's done 105,000km with no issues yet, but I fear I've left it a little too long. But the point of my post; I'll check with the Ford dealer about their fluid prices.

Can you get away without knowing the exact oil temp when refilling? I know for older boxes mfrs just said 'hot' or 'cold'...

The spec. for a replacement fluid is ATF T WS. Ravenol oil has ATF T WS LIFETIME FLUID.
Toyota also has the ATF T WS ON ITS WEBSITE.
About $60.00 for 4 litres.
 
Is the original poster of this thread an update may be useful. Four years on, the transmission oil has been changed twice in 60 000 kilometres. These last times using the drain and refill the same amount method rather than the "flush". I have elected to use NULON full synthetic transmission fluid. The slurred 2/3 changes are now very very rarely poorly performed under the absolute lightest of throttle so it could be "driven around" anyway.
I am convinced a change with suitable fluid is more important than the branding or source of the oil. When drained the dirty stuff is an oxblood colour and not transparent, unlike the delicious clear cherry red of new stuff.
 
Fritz, do you mean just changing only about a third of the oil each change (or whatever amount comes out when you just drain it)? Or drain, fill, run drain fill run etc. Or is the latter what you mean by flush?

Incidentally, I saw a US website for their Mondeo equivalent where a guy disconnected a pipe from the trans cooler (Mondeo has one) and started the car to pump the oil out. Sounded dodgy.
 
Update from the TOTAL engineer the Aisin 6 speed auto should have Toyota Type T-IV/JWS 3309 or equivalent which is met by Total FLUIDMATIC MV.
They have also told me that the engine oil recommended for the RHH ENGINE is now Total Quartz Ineo First 0W30.

The initial post dealer service ( who wouldn't have touched the auto anyway because of its age ) was a FLUSH, since then the partial drain and replace with the same amount as was drained out has been done. The biggest hassle was an overtight drain plug and one was sourced before its most recent drain. These plugs are somewhat specialised and not garden variety, so to ensure we didn't get up a dry creek the new drain plug was sourced before proceeding. A friend who drives a Hyundai also discovered Hyundai had no transmission drain plugs in Oz, so discretion was practised until he had one in his hot little hand before proceeding.
 
Hi Guys,

This post seems to be a bit of a merry go round, repeating its self over and over. So I'm probably doing the same thing?

Firstly, the drain plug is a 2 piece setup, a level plug and a drain plug. The drain plug itself is fairly small, and you need to remove the level plug to drain what you can from the transmission (around 3 litres).

Everyone keeps talking about flushing, but never any explanation? The only way I can see that you could flush the transmission, would be to do an initial drain, and replace the level plug. Top up the transmission until oil starts running out the level plug, start & run the engine and continue to add oil (with only the level plug fitted) until the oil starts to run clean from the transmission. Changing gears a few times would also help? It's the oil in the torque converter that you are trying to drain.

Once the oil is clean, stop adding oil, and fit the drain plug when the flow is reduced to a drip.

This is a fairly wasteful way, but probably useful if the car has over 100,000 K and never drained.

As to the oils, as I posted earlier, there are two factory oils for the AM6. The C5 & C6 cars with the 3.0 Lt. diesel engine are fitted with a low friction gearbox, and a very low viscosity oil. Late C5 2.2 litre cars are also fitted with a similar gearbox.

I've been told that both these boxes can run Penrite transmission oil, and from my own experience Nulon's multipurpose full synthetic transmission oil is also fine.That info comes from a very reliable source, and that they use Penrite themselves.

Our old 2006 C5 HDI now has 290,000 ks on the clock, and the transmission oil has been changed fairly regularly from around 35,000 ks, and used Nulon exclusively, and the transmission works perfectly.

Whether changing the oil prevents the valve body problems is open for discussion, same goes as to whether changing the oil cures the valve body problems, but the oil change certainly improves changes and overall gearbox performance.

Best regards,

Greg
 
One site said this:"every time the oil is changed the "oil counter" MUST be reset - the box is adaptive and needs to know about such things as it makes a huge difference."

Is it imperative that the transmission oil counter be reset (for an AM6) when transmission fluid is changed? What does resetting achieve?
 
It depends on the age of the engine/transmission combination - Euro 5 on, or before that. The genuine stuff is made for Aisin and supplied in this country by dealers (Toyota are cheaper than Citroen).

Some AF contributors are using non-genuine makes such as Penrite; there's a constant discussion.
 
Toyota oil is cheaper than penrite

I paid $240 for 20 liters of total ,sydney, and same price gold coast ,we have three cars with this box , including a picasso that was cured from slamming in reverse and second when hot, with an oil change ,perhaps we were lucky ,two 307 hdi in tweed and the peco lives in sydney .pugs
