After some "spirited" driving on the weekend my ATTESSA has decided to put most/all the power to the rear wheels. My dash light is off and the torque spilt gauge is working fine but 3rd gear fishies mean something is playing up.

Now I'm assuming that the transfer case is gone, which I'll just replace if it has but I'm crossing my fingers that because the fluid in the tank is a bit low (just under min) it may have got a airlock in the system. I know how to bleed the system and have some nissan fluid to do it and will try on the weekend...

But in the meantime am i just wasting my time because its definatley the transfer case or is it worth bleeding the system?!?

well i did say spirited driving haha

oh yeah the other thing i did that might mess things up was switch the car from 4wd to 2wd while the atessa was working very hard...

would this have done anything to the computer etc to cause this?!?

sorry guys for butting in. I tried bleeding the ATTESA sytem when i first got the car. You have to disconnect the green plug at the kicker plate. It was damn hard and i coulnt disconnect it. Any tips??? As how to disconnect the plug easily? Cos i have topen up the line at the underneath the rear of the transmission. Cos i got a leak on it andd im trying to determine whete is the gasket or an O ring on the fitting. But before i take the line out i have to make sure that im able to bleed the system after. Lemme know. thanks

The transfer case uses a wet clutch system. These clutch plates only have a finite life, and 10+ years is well and truly in the "finite" catagory.

When you rebuild the case you can squeeze some extra plates in there (along with a couple of extra "tricks") to give a really quick uptake. Combine this with an ATESSA controller and your R32 will be transformed on the track.

ok i finally got around to bleeding the system on the weekend... its seems to be fine and have no air in it.

BUT

while i was changing it i noticed that the attessa pumps would kick in for no reason every 10 sec or so when car was just idling, you can clearly hear a relay clicking and then when bleeding from the nipple above the diff a tiny little burst would come out with what looked like air.

plus on top of this the fluid resivoir has the top section and then the bottom section, with a spacer between. in all systems other than mine the bottom section has a air space in it... mine doesnt

any comments suggestions thoughts?!?

      I swear at my GKTech ones every time I have to take them apart and replace a spherical. But I wouldn't swap them for anything else. They absolutely slay every other option, at least in terms of how they actually work. You sure you don't want to live with bearings? I mean, they don't have "ball bearings". They are rod ends and sphericals throughout. Tough as nuts, even though I have found more than one way to wear them out.

      From when I was looking at getting the 86 engineered for the turbo, the joint said to put in a few euro 5 or 6 cats, then tune the car on a nice clean E85 tune When I was looking at a turbo for the MX5, it was basically the same thing, a couple of cats and a nice clean tune Although, it will depend on the year of the Jeep IRT emmisions standards required, and what mods are done, especially if it has a newer engine installed that requires a higher Euro

      Yeah - but it's not actually that easy. There are limits for HC, CO, NOx and particulates. Particulates shouldn't be a concern in any petrol engine unless trying to comply to the very latest Euro standard. But getting a tune right so that all the others stay within limits AT THE SAME TIME is not a trivial exercise. You couldn't possibly get it right by just guessing at the tuner's dyno, unless he had a 4 gas analyser up the pipe, which is not often the case these days. It used to be. Every decent shop that did "tune ups" (as opposed to tuning) would have a 4 gas analsyer. Perhaps there's still quite a few of them around these days. But most "tuners" are only watching O2 and power readings.

      Slight segway but the most expensive part of the whole thing which I would have thought would only be required for an engine size/type swap, not a VIV test, is emissions testing.  That's when you get into the big bucks.  I can't remember the exact price now but I got quotes for the GT-R based on swapping to RB30 (not that anyone bothers doing it legally anymore...) and it was around $4500 just for that alone.  The guy that does them manipulates the tune on the vehicle to make sure it passes.  The cheaper option is to book into Kangan Batman Tafe (I think that's where it was) and hire their tester.  Allegedly you're not allowed in there with the car though so not in a position to tweak anything to make sure the vehicle passes.  I'm sure in this day and age of ultra tuneable ECU's you could get the tuner to program a special efficiency (clean) tune that emits the lowest amount of particulates possible that would pass the test.  It might only make 50kW's but as long as it passed who cares!

      I'm sure he has left signs, or, he is looking down, laughing That's my cunning plan for when I leave, lots of half finished projects, with no rhyme or reason of where I was actually up to, just to keep everyone on their toes
