Hi Stu,

Deff worth doing it your self to avoid some ham-fisted incompetent mechanic doing a sub par job on your car. Your right it happens to much and if they do do a descent mechanical job, theyv'e probably left you with a few signs that they have been there in regards to your body work ect...

Drain and filler plugs for the diffs- Drains are on the bottom and stand out like dogs balls, as for the filler im pretty sure they are on the drivers sid about half way up each diff.

Transfer case - one is on the side and the other is on the back part of it as you look at it from the rear of the car. If i were you stu i'd drain the oil out of the trasfer case, then remove the pressure line coming from the pump that goes onto the back of the box, this will drain the boot compartment cansiter and give you the chance to change/flush all the fluid in the system. Once its drained connect up the line and remeber to fill the attessa reservoir in the boot. Also you will have to bleed the attessa system if you do this method. With the cars ass in the air, start car, crack nipple on trasfer case untill no bubbles just straight fluid comes out, then lock it off, move to back diff and somehow get your spanner on the nipple above the rear diff and do the same. Drop car down and check level in rear canister while the car is running.

Quantities wise I think the diffs took about 1.5L in each and transfer roughly 2.5L. You just fill it up till a bit spills out the filler plug and its sweet.

Diff Oil- Castrol SAF-XA 75W140

Transfer case- Castrol Transmax Z

Crack the filler bolts before the drain bolts to ensure you can fill them back up again :-)

Good advice dude, dont share any of your knowledge or anything...

Not necessary for a oil change, no covers need to be removed and no gaskets need to be changed.

If you want to ruin the transfer case and then pay a hefty bill for attessa repairs yes you could, if you look at a GTR box you can see the shifter assembly is above the transfer case section of the box, pour oil into here and its going into the transfer case not the gear box....

Would this one be ok for my gearbox

Gearbox oil will be OK. Just use another brand for the diffs if you can't find the Castrol. Nissan reccommend Hypoid gear oil GL5 85W-90 for the front diff (approx 1L) and LSD (if you have a mechanical LSD) GL-5 80W 90 for the rear diff (about 1.5L) You could use something heavier for Australian conditions or Motul if you want to splash out!

The drain plug on my diff is easy enough to find.

However I think my S2 RS4 has a reservoir to store the fluid.

Anyone know if this is a diff reservoir? The diff looks like it has a pump above it.

Do you just drain it and fill the reservoir ?

Thanks

That's the reservoir for the Attessa. the stuff on top of the diff is the attessa pump and accumulator. There is a bleed nipple above the diff and one down by the gearbox extension.

Thanks, So that reservoir is for the transfer case then ?

Yeah the diff filler is on the passenger side, half way up towards the rear of the diff.

The oil in the boot reservoir looks pretty brown and a bit low, So i'm going to replace it and the front diff as well.

      Mistakes were made, my R34 Story

      Have a look at that (shitty) pic I posted. You can see AN -4 braided line coming to a -4 to 1/8 BSPT adapter, into a 1/8 BSPT T piece. The Haltech pressure sender is screwed into the long arm of the sender and factory sender (pre your pic) into the T side. You can also see the cable tie holding the whole contraption in place. Is it better than mounting the sender direct to your engine fitting......yes because it removes that vibration as the engine revs out 50 times every lap and that factory sender is pretty big. Is it necessary for you......well I've got no idea, I just don't like something important failing twice so over-engineer it to the moon!

      Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.

      How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP

      Jacks that fit under GTR lips that can reach the subframe?

      I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use

      I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.
