Hey Guys, Some Advice?

[V8or4X4]

Hey Gurus and Gurettes, my front/ rear torque gauge thing(to the left side of cluster) doesn't respond and sometimes my rear tyres screech around corners, does this mean I'm only running 2wd? I havnt pushed her too hard yet so pretty important to knOw.

Update;

Ok, silly me. all this talk about fuse breakers made me do the obvious.. CHECK MY FUSES!! Turns out my(under the hood) 4wd fuse was put in the empty spot nxt to where it should have been. It look intact so I went to put it in place(with ignition off obviously) and I could hear a buzzing from the rear of the car so I panicked and pulled it. Is this normal? Can any of u gurus work out why he would have moved the fuse out of line? Cheers all.

Jesse.

buzzing is normal, its your attessa pump

open up the boot, on drivers side corner by the tail lights, make sure u have fluid as marked on the reserviour

Thanks BWRGTR, I'll try that as soon as I get home.

Buzzing with the ignition off is a bit wierd..

[V8or4X4]

That's what I thought, Bubba.. I'm gonna have a go flushing and bleeding the system today and I'll see what happens. The previous owner said there was a leak somewhere is the system, does anyone know of a weak spot or somewhere it's most likely to leak from?

[V8or4X4]

Or how to completely drain the reservoir so I can pull it out for inspection?

Cheers guys!

Hi all, I'm still stuck here, any advice would be greatly appreciated.

I will start from the beginning and hopefully someone here has experienced this before or can suggest trouble shooting methods.

When I bought my 89 GTR(as even more of a skyline noon than I currently am!) the previous owner told me the 4wd function wasn't working properly and had been "switched off" by a nissan mechanic due "a leaking switch". He was leaving for nz for a few weeks the next morning so I bought it on the spot(impulse buy and a half). Having read countless pages on the attessa system on both this site and others I began my own basic troubleshooting.

1. Fuses: cabin 4wd fuse is intact. In-bonnet 4wd fuse intact but moved to the "spare" fuse slot! Tried the fuse in position with my keys in my hand and immediately heard a buzzing sound from roughly under the rear seats. Not knowing what this was I quickly pulled the fuse out again.

2. Fluids/reservoir: Checked my attessa fluid level(thanks BWRGTR!) which was very low. Got some TQ-DIII to fill with and ended out pulling the entire reservoir out with the hoses so I could drain it fully and clean it off. The previous owner also mentioned there might be a leak in the attessa tank itself and this looked believable by the residue on it and the hoses. After close inspection I was sure it must have just been spilt when filling. Refitted.

3. Filling and bleeding: Followed the DIY by Black R32(thanks dude!) but wanted to get some fluid through the system before getting the attessa motor going. Filled the reservoir through the top filler cap pretty much to the top. Now I wasn't sure how to bleed the fluid into the bottom half of the reservoir. First tried loosening the bleeding nipple on the nipple closest to the front of the car and had abOut 30ml of what looked like this come out..

Next I disconnected the air bleed connector plug with the bleeding point cracked and then tried the fuse in the engine bay again. It is important to note that when the fuse is properly inline the Attessa pump can be heard buzzing and does not stop so after a few seconds I pulled the fuse back out. This time the reservoir was half empty meaning some of the fluid had bled somewhere. I refilled reservoir and went to repeat the steps. This time though the fuse was stuck in the fuse box and the pump ran for about 15 seconds then stopped. Once I got the fuse out I saw the reservoir level had barely changed, nothing more had bled from under the car but now there was sh1tloads of(still fairly clean, red) the tranny fluid running down most sides of what I think is my rear diff..!

Diagnosis: Guys, what have I possibly broken/blown up here?

Being that the fluid running was the fluid I had just put in, it is probably attessa only related and therefore car can still be driven in RWD? If this is the case could it have already have been leaking and maybe the leak Old Mate who used to own the car was talking about?

Any which way, has anyone ever been through this or would know the best way to begin dealing with this? Important, I don't own ramps so this work was done with my rear wheels on a kerb thus my vague description of where it's leaking from.

Thankyou to ANYONE who stuck through my novel this far. cheers especially if anyone has light to shed on this problem I have.

Come on guys, anything?

[RRob]

The Attessa pump and valve assembly is bolted to the top of the rear diff. Diff out job to inspect/replace damaged parts.

[V8or4X4]

Farrrk!

Is the car driveable in RWD?

[R.3.2.G.T.R]

should be, pull the fuse marked 4wd in the engine bay

did u find out what was leaking - diff??

best to take to workshop so u can look under the car properly, red fluid could the attessa fluid leaking and u might be able to fix the leak the previous owner was talking about

[V8or4X4]

That's what I'm hoping, BWRGTR. With any luck it's a hose or something. Do u guys think I will be able to assess on ramps what's leaking or full car lift?

[V8or4X4]

Well guys, got front wheels on a kern and back on ramps and I could get under it. This is what I'm pretty sure is leaking looking up diagonally toward the back of the car in just above the diff. I assume attessa.

So diff out and replace? Doesn't sound doable in my driveway.. Has anybody done it here? What's involved?

Thanks for the input guys.

Jesse.

u definitely should take it to a workshop mate, get a professional to have a look for u on a hoist
