not going against what your saying, but ive been tod by ALOT of trans auto joints that its not bad to overfill by a little, and that a lot of trans joints actually overfill

That's cool, most trans places will also tell you Dextron III is okay for the RE5 trans.

Just forwarding on what I have experienced with mine in that past :)

Kewish overfilled mine knowing I was going to put a cooler on which would suck half a litre out. They also filled it with Dextron III as the clutches have been replaced with aftermarket. I wouldn't recommend Dextron with a stock gearbox though, its probably why mine blew in the first place.

Why is that though? Dextron would kill the gearbox, but Matic J/S dont.

And the Nulon and Valvoline trans fluids are Dextron III and Matic J compatible?

Just curious... Seems kind of strange...

Sure, I get that, but if Dextron III is so deadly, how can you use something which is compatible with it and Matic J? You wouldnt get an engine oil which was 25w60 but compatible with 10w40?

The clutch friction material doesn't like it, mine used to flare to redline on the freeway occasionally at part throttle, then be fine for a while. The valve body is setup for a particular grade and friction and anything outside that may cause issues. Once you get your valve body modified it "may" be ok to use but i'm not guaranteeing it.

thats true. mine is just above the line while the car is hot and on, with the trans cooler. i havnt had any problems, but yeh i can see what you mean.

rebirth of an old thread :) about to do my oil change. So Matic S is the way to go? i have called Nissan they say they have never heard of it.. lol. They only stock Matic J. $70 for 5L. (btw i did try a search though i cant put "matic s" as the s breaks it as being too small! - i put in Matic though got way too much irrelvant stuff)

Anyone know where i can get some Matic S from or some something equivalent?

So will need 5L for the box and another 5 for a flush?

Thanks for your help gents.

Matic J is the way to go. You'll need 2x 5 L for the full gearbox / Converter (will have a little left over). From memory mine was ~$60 for 5 litres.

Matic D is to be avoided.

Nulon full synth is also an option. I didn't use it.

I used Matic-J, it actually ended up being cheaper to buy 2x5 (10 litres) and end up with a litre odd spare, than to buy 3x4 (12 litres) of Nulon and end up with 3 litres spare.

Used Nulon in my M35 for years (about 140,000kms)... with and without coolers and no issues with the trans.

Will be used in the PNM35 when it rolls up.

Also use it in the wife's 380 (and "Ol' Reliable" - 2003 Magna), both of which are notoriously hard on trans fluids, without issue.

Matic D is effectively Dextron III.

Matic J is a semi synthetic fluid

Matic S is a 100% synthetic fluid and is the replacement for Matic J.

You should be able to get Matic S from the US without a prob if you want that.

I can't believe that we still have Matic J in Aus. Typical of Nissan Australia I guess.

You will need to disconnect a cooler line to get all the fluid out. I imagine in principle its similar to tC34:

Dropping the sump on the auto box will only yield around 1 or 2 litres but at least then you can clean the fiter (its steel) and pan and then put it back together. then take off a hose from the transmssion oil cooler and run the engine until you have collected a couple of litres. Stop the engine and pour 2L of new atf down the dipstick (for the auto trans ) and repeat til the oil comes out clean. Could take 10 to 12 Litres.

would it work if you pulled the cooler pipes off, chuck a bit of hose onto the return point on the trans

you new hose goes into the new bottle of oil, the return goes into the bucket/oil pan

then run the car with someone watching the new bottle

so it sucks up clean stuff and spits the old stuff into the waste bucket/pan

It won't suck up the clean fluid. It is a pressure pump at the start of the circuit not a vacuum pump at the end.

It forces fluid from the sump, through the cooler circuit and returns it to the sump with essentially no pressure.

If you invert the bottle you have the clean fluid in (gravity feed) it will all run into the sump; you will have no way to control how much goes in.

Just pump out a couple of litres at a time and pour in the same.

Lol, OK, there's a reason why it won't work. But it sounded so damn logical..

    • I know why it happened and I’m embarrassed to say but I was testing the polarity of one of the led bulb to see which side was positive with a 12v battery and that’s when it decided to fry hoping I didn’t damage anything else
    • I came here to note that is a zener diode too base on the info there. Based on that, I'd also be suspicious that replacing it, and it's likely to do the same. A lot of use cases will see it used as either voltage protection, or to create a cheap but relatively stable fixed voltage supply. That would mean it has seen more voltage than it should, and has gone into voltage melt down. If there is something else in the circuit dumping out higher than it should voltages, that needs to be found too. It's quite likely they're trying to use the Zener to limit the voltage that is hitting through to the transistor beside it, so what ever goes to the zener is likely a signal, and they're using the transistor in that circuit to amplify it. Especially as it seems they've also got a capacitor across the zener. Looks like there is meant to be something "noisy" to that zener, and what ever it was, had a melt down. Looking at that picture, it also looks like there's some solder joints that really need redoing, and it might be worth having the whole board properly inspected.  Unfortunately, without being able to stick a multimeter on it, and start tracing it all out, I'm pretty much at a loss now to help. I don't even believe I have a climate control board from an R33 around here to pull apart and see if any of the circuit appears similar to give some ideas.
    • Nah - but you won't find anything on dismantling the seats in any such thing anyway.
    • Could be. Could also be that they sit around broken more. To be fair, you almost never see one driving around. I see more R chassis GTRs than the Renault ones.
    • Yeah. Nah. This is why I said My bold for my double emphasis. We're not talking about cars tuned to the edge of det here. We're talking about normal cars. Flame propagation speed and the amount of energy required to ignite the fuel are not significant factors when running at 1500-4000 rpm, and medium to light loads, like nearly every car on the road (except twin cab utes which are driven at 6k and 100% load all the time). There is no shortage of ignition energy available in any petrol engine. If there was, we'd all be in deep shit. The calorific value, on a volume basis, is significantly different, between 98 and 91, and that turns up immediately in consumption numbers. You can see the signal easily if you control for the other variables well enough, and/or collect enough stats. As to not seeing any benefit - we had a couple of EF and EL Falcons in the company fleet back in the late 90s and early 2000s. The EEC IV ECU in those things was particularly good at adding in timing as soon as knock headroom improved, which typically came from putting in some 95 or 98. The responsiveness and power improved noticeably, and the fuel consumption dropped considerably, just from going to 95. Less delta from there to 98 - almost not noticeable, compared to the big differences seen between 91 and 95. Way back in the day, when supermarkets first started selling fuel from their own stations, I did thousands of km in FNQ in a small Toyota. I can't remember if it was a Starlet or an early Yaris. Anyway - the supermarket servos were bringing in cheap fuel from Indonesia, and the other servos were still using locally refined gear. The fuel consumption was typically at least 5%, often as much as 8% worse on the Indo shit, presumably because they had a lot more oxygenated component in the brew, and were probably barely meeting the octane spec. Around the same time or maybe a bit later (like 25 years ago), I could tell the difference between Shell 98 and BP 98, and typically preferred to only use Shell then because the Skyline ran so much better on it. Years later I found the realtionship between them had swapped, as a consequence of yet more refinery closures. So I've only used BP 98 since. Although, I must say that I could not fault the odd tank of United 98 that I've run. It's probably the same stuff. It is also very important to remember that these findings are often dependent on region. With most of the refineries in Oz now dead, there's less variability in local stuff, and he majority of our fuels are not even refined here any more anyway. It probably depends more on which SE Asian refinery is currently cheapest to operate.
