thought id do a big bump on this one.. I am still getting the blip of power to the front wheels (shows up on the front torque gauge) now and then usually when the gearbox shifts from first to second gear.. no 4WD light ever. (thanks scotty - that was just a faulty relay). Though this blip of power to the front wheels even when using very low throttle causes the car to do a very ugly shift into second. or very occasionally a slight surge at 60-70kmh.

If i pull the relay and have the 4WD light come on (hence RWD only) car is smooth as silk.

also smooth as silk if i flick to synchro.

Anyone else have this problem? Going to bleed the atessa with scotty in the next couple of weeks though would like to see if anyone else has any ideas.

just been doing some googling. Some people are saying that it can be caused by non-matching front and rear tires.. I run factory ARX 18's they did come with 235/50/18 though i changed them to 245/45/18. surely it cant be that??

Cheers.

If all the tyres are matching there isn't much else you can do, unless the fronts are worn more than the rears?

Hopefully it just needs a flush, new fluid can only help it, and get rid of any built up air in the system.

Today I had my first encounter with exactly the same thing between 5-10% torque showing on the gauge in 1st gear and into the beginning of 2nd... No green 4WD light up on dash either.

Made the car sound like it was working extremely hard but performance was anything but. Didn't at all turn the tyres was probably best described as like a slipping manual clutch sensation...

Ok it had been very lightly drizzling in Adelaide, still I had pictured qtr turn of opposite lock to be the result...?

Only owned NM35 for a couple months...

So is this the normal occurrence

just an update for those following and or having the same problem. My car was due for a front right wheel bearing.. This seems to have been causing issues with the atessa. making the car pulse power to the front wheels when cruising (50-80kmh). Also even gave me a symptom like fuel cut when using near or wide open throttle. both these things have been fixed by the wheel bearing replacement.. (thanks Scotty!).

quite strange. we bled the atessa fluid too. so now i am back tot he occasional blip of front torque when going from first to second.. no other symptoms..

yeah mate. running real well i reckon that atessa bleed has helped too.. just need to do that dif bush let me know when you get em in :)

I sent diff bushes down to Scotty last week, if Auspost get off their arses they should have them to him shortly.

you may be interested - in cold Russia the most suspicious part of ATTESSA is used to be the pressure control switch, which causes C1208 error reading

this is one of this crap pieces

Nice one Erop, I have an assembly here with pressure switch problems, I might give this switch a shot. Thanks.

You don't happen to have a part number for the correct pressure and thread do you?

this switch is only marked with PS-20

the WAKO doesn't sell less than 1000 pcs :angry::angry:

now looking for byuing this switch, still no exact code, Scott's right

BUT - you may take it from R32-R34, Laurels, Glorias - their ATTESSA is similar in such parts, and their used spares are cheaper

in my mind - the reason is lack of changing of this fluid, which causes mechanical problems in winter, cause my one (350K on odo since 2001) still works, i replace the ET-S fluid every year

    • Didnt realise RB's had more then 1 head.
    • I'm normally copping my own abuse from neglecting my daily drivers. "Those suspension bushes will last a bit more", "Don't worry about the oil leak, just keep topping it up". The project cars I'm always doing things slowly on them as I'm wanting them to be done better, and neater, and nicer. Luckily I don't have to deal with 18 year old Matt's "Learning to wire" stuff in the project cars. And there's only one piece of wiring I'm displeased about in the Landcruiser, and it's about to be cut out... However, the box loads of parts that have been going through this place lately for the Landcruiser... Brake pads Brake Rotors Full handbrake overhaul Wheel Bearings Seals Swivel hubs Steering Boxes Half the suspension joints Shocks Air bags (Ones to go in the rear springs for towing) Water pump Timing kit Lower timing case Harmonic Balancer Radiator Lots of other little seals and shits Gas struts for the bonnet New power window switches And god knows what else I've forgotten... Ha ha ha I have my fingers crossed the pinion seals don't start leaking on the diffs, that the transfer case doesn't leak, and the gearbox input shaft doesn't leak, nor the rear main seal. As they're about the only seals I haven't replaced in the driveline! I'm seriously eyeing off buying new caliper rebuild kits front and rear brake calipers... I'll probably recheck all the valve clearances soon too, and hopefully, it should be all good and sweet to haul some long distance trips again!
    • Every time I pull my 3x gauges out of the console and see the crack-addict way that I did the wiring, and I just can't bring myself to tear it all apart and "make it nice", because it is currently working. In fact, the last time I was in there I probably made it worse.
    • The best part is when you own the car long enough that you look back and find your OWN ham fisted amateur shit!
    • The annoying part about neglect, is when you start to replace one thing, and find ten more broken things. Ham fisted monkey repairs you normally only find out about when trying to do something unrelated! Ha ha   Neglect you can kind of anticipate the huge costs to fix it all. Ham fistedness is normally a shock the first time your work on a new old car, as everything "looked" good before.
