Attessa Problem R32 Gtr

[SimonR32]

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?!?

[funkymonkey]

maybe you just have some air in the lines? have you tried bleeding the system?

[SimonR32]

im going to on the weekend...

After seeing your vid on Antilag I'm not suprised.

[SimonR32]

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

to the OP, check the boot for the Attesa error code LED flashes.

stasis, check the diy section for a guide on how to bleed attesa. it helps if you have a friend to help.

even with a little air in the line you will still get front drive to a point.

Sounds like your transfer has called it a day. They are not overly difficult to overhaul.

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.

but i dont wanna put u to shame gav

Don't worry about that - plenty of rear wheel drives out there manage to "shame" me :laughing-smiley-014:

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?!?

Have you done this?

pump is shagged... mine blew up and was constantly on.

[SimonR32]

the dash light isnt on and no leds flashing...

how hard was the pump to replace ronin?

[Ronin 09]

i didn't do it but the suspension shop did it.

it's a diff out proposition.... there's a section in the manual that describes how to do it

[SimonR32]

diff out is ok

i was worried it was a subframe out
