My ATTESSA reservoir in the boot of my 32 is low... what fluid is it (and don't say it is ATTESSA fluid!) and where can i buy it? Is it a tranny oil or a P/S oil or none of the above?

Cheers

Accordng to the factory WS manual it uses "Nissan Power Steering Fluid Special"

At a pinch you could use ATF.

Most people use a Dexron III compliant ATF for the actuator. Technically, your not meant too: you should use only Nissan Power Steering Fluid Special (NPSFS) according to some heavyweight at Nissan Japan.

Speaking to SydneyKid, he said the only reason for this is because NPSFS is designed with snow/ice condition in mind.

Anyway, I was just wondering if anyone actually managed to find NPSFS and how much it cost (for interests sake).

The Nissan Special Power Steering Fluid is Nissan Matic D which is their ATF. I got a few litres of it for $20 from Nissan spare parts in Canberra. I cant remember exactly how much it was as it was 12+ months ago now.

What is the best way to bleed the actuator oil?

For interest sake, here is what the guy from Nissan Japan had to say:

1. Transfer case fluid

Nissan Matic D is strongly requested because high torque is applied to

transfer unit.

2.. Transfer case (ATTESA E-TS-PRO Actuator) : It is not acceptable to use

DEXRON III fluid.

> Only Nissan Power Steering Fluid Special use is required.

Today I received the technical information from our design department.

1. The difference between the DEXRON III and Nissan Power Steering Fluid Special

The viscosity characteristic of Power Steering Fluid Special is lower than that of ATF DEXRON III and the resistance to wear is also improved. Each viscosity is the same level at 100 deg.C and the former viscosity is designed to have the lower value for under 100 deg.C than the latter viscosity.

This characteristic is aimed to rotate an oil pump located in ATTESA PRO actuator easily at the extremely low temperature (Around -30 deg.C or -40 deg.C)

2. What will happen if a customer puts DEXRON II or DEXRON III into the ATTESA PRO actuator reservoir in the trunk ?

The 4WD performance will be largely decreased at the low temperature because the viscosity value of DEXRON II or III is extremely high compared to that of Power Steering Fluid Special; As the rising characteristic of 4WD torque transfer becomes worse, it takes the longer time to transfer the driving torque to the front wheels. There is a possibility that the 4WD cannot be achieved in the worst case.

My understanding is that Matic D is "Nissan Power Steering Fluid"; "Nissan Power Steering Fluid Special" is different again.

LW.

Nissan Matic D is Nissan Special Power Steering Fluid. Ill find the bottle if I still have it and take a photo.

Its what Nissan reccomend to use, its easily obtainable, its not stupidly expensive so I dont see any reason as to why youd use something else.

There are 2 bleed points. Put the car up on stands and start the engine.

The first bleeder is at the rear of the transfer case it will bleed itself when the nipple is opened. The second bleed point is much tricker it is above the half shaft right up on the chasis.

Nissan Matic D (Dexron II/III analog as i think), Nissan PSF and Nissan Power Steering Fluid Special are different fluids.

See http://www.nissan-sp.co.jp/oil/ for details, there are some pics of OEM fluids on this page. It`s written in japaneese, use online translators for reading.

The p/n for Nissan PSF Special also known as "attesa operating fluid" is: KLF30-00001 or KLF30-00004 (the last figure is for can capacity in liters).

While preparing to manual conversion I`ve ordered 4l of this fluid at auto.vl.ru -- i`m not sure this link can be usefull outside of Russia, but you can try to order it somewhere in Japan using the right partnumber.

no the wheels don't need to turn the atessa pump has pressure as long as the engine is running.

And for what its worth we just use a synthetic auto trans fluid and it has always worked fine including races and targa tas

i hav a r33 gtr and a-lsd light turned on, i had to turn the car off n on again for it to go away. this happened once in a while then more often. i gather it was getting worse until it just stayed on. found out that the pump was dead, openened it up to find the one of the magnets was broken and three of the four brushes were completely worn out.

i bought a second hand unit which fixed the problem but it started to hav the same symtoms again. i gather that the replacement unit is also 10years old and cant be much better than my old one.

i hav rung up nissan and nearly died when they told me its gonna cost nearly 6 THOUSAND dollars !!!! just to buy that part.. my problem is i cant find any place here in melb or australia who can repair it.

i also noticed sumtimes when u turn the key to acc i can here the 4wd relay ticking endlessly.

will try to plug in dianostics but unsure if that can identify any problems or electrical faults.

any suggestions ????? confused....

      I'd be installing 2x widebands and using the NB simulation outputs to the ECU.

      R33 GTS25 NA - Stalling when vehicle is at operating temp

      By GTSBoy · Posted

      Nah, it's different across different engines and as the years went on. R32 era RB20, and hence also RB26, the TPS SWITCH is the idle command. The variable resistor is only for the TCU, as you say. On R33 era RB25 and onwards (but probably not RB26, as they still used the same basic ECU from the R32 era), the idle command is a voltage output of close to 0.45V from the variable resistor.

      R33 GTS25 NA - Stalling when vehicle is at operating temp

      It's actually one of the worst bits of Nissan nomenclature (also compounded by wiring diagrams when the TCU is incorporated in ECU, or, ECU has a passthru to a standalone TCU).... the gripe ~ they call it the TPS, but with an A/T it's actually a combined unit ...TPS (throttle position switch) + TPS (throttle position sensor).... ..by the looks of it (and considering car is A/T) you have this unit... https://www.amayama.com/en/part/nissan/2262002u11 The connector on the flying lead coming out of the unit, is the TPS (throttle position sensor) ...only the TCU reads this. The connector on the unit body, is the TPS (throttle position switch) ...ECU reads this. It has 3 possible values -- throttle closed (idle control contact), open (both contacts open, ECU controls engine...'run' mode), and WOT (full throttle contact closed, ECU changes mapping). When the throttle is closed (idle control contact), this activates what the patent describes as the 'anti stall system' ~ this has the ECU keep the engine at idling speed, regardless of additional load/variances (alternator load mostly, along with engine temp), and drives the IACV solenoid with PWM signal to adjust the idle air admittance to do this. This is actually a specific ECCS software mode, that only gets utilized when the idle control contact is closed. When you rotate the TPS unit as shown, you're opening the idle control contact, which puts ECCS into 'run' mode (no idle control), which obviously is a non-sequitur without the engine started/running ; if the buzzing is coming from the IACV solenoid, then likely ECCS is freaking out, and trying to raise engine rpm 'any way it can'...so it's likely pulling the valve wide open....this is prolly what's going on there. The signal from the connector on the flying lead coming out of the unit (for the TCU), should be around 0.4volts with the throttle closed (idle position) ~ although this does effect low throttle shift points if set wrong, the primary purpose here is to tell TCU engine is at idle (no throttle demand), and in response lower the A/T line pressure ... this is often described as how much 'creep' you get with shifter in D at idle. The way the TPS unit is setup (physically), ensures the idle control contact closes with a high margin on the TPSensor signal wire, so you can rotate the unit on the adjustment slots, to achieve 0.4v whilst knowing the idle control contact is definitely closed. The IACV solenoid is powered by battery voltage via a fuse, and ground switched (PWM) by the ECU. When I check them, I typically remove the harness plug, feed the solenoid battery voltage and switch it to ground via a 5watt bulb test probe ; thing should click wide open, and idle rpm should increase... ...that said though, if it starts & idles with the TPS unit disconnected, and it still stalls when it gets up to operating temperature, it won't be the IACV because it's unused, which would infer something else is winking out...

      In the context of cam 'upgrader' I mean generally people who upgrade headers/cams - not my specific change. I mean it makes sense that if I had a bigger cam, I may get more false lean readings. So if I went smaller, I'd get less false lean readings. To a point where perhaps stock.. I'd have no false lean readings, according to the ECU. But I'm way richer than stock. My bigger than normal cam in the past also was giving false rich leanings. It's rather odd and doesn't add up or pass the pub test. Realistically what I want is the narrowbands to effectively work as closed loop fuel control and keep my AFR around 14.7 on light sections of the map. Which is of course the purpose of narrowband CL fuel control. So if I can change the switch points so the NB's target 14.7 (as read by my WB) then this should be fine. Haven't actually tested to see what the changed switchpoints actually result in - car needs to be in a position it can idle for awhile to do that. I suspect it will be a troublesome 15 min drive home with lots of stalling and way too rich/lean transient nightmare bucking away for that first drive at 2am or whevener it ends up being. Hopefully it's all tune-able. Realistically it should be. This is a very mild cam.
