So i decide to service my car today (R32 GTR)....drop all the fluids etc etc. Go to undo the gearbox filler cap and RED yes RED oil comes pouring out the filler. Then drop the drain plug and even more. Undo the transfer case drain plugs...a drip comes out.

The transfer case is leaking (more importantly - pumping) ATF into my gearbox...has anyone had this experience??! No wonder it was hard selecting gears...

Gearbox is out...pulled the case off it cant see anything obvious. Can anyone recommend a good place to take my transfer for repair? Cos obviously the main seal or pump gasket is leaking...

The car has done 1,100km since a full rebuild, and the transfer was reco'd, i have no idea what is was like before.

Any help or experiences appreciated,

Cheers,

Mat.

I bought a VS 5ltr 5speed many years ago when they were around 3years old, it had a shifting problem when cold (that I noticed upon test driving) and on higher than normal rpm gear changes (that I also noticed on test driving) they said no problems they will sort it out.

They being... 'au....... motors"

Upon purchasing the car I noticed the notchy, slight crunch and slip out of 5th gear was still there so I took the car back for warranty.

I got the car back and it was fixed. No more crunch and no more slip out of 5th. Later down the track it started slipping out of 5th, I discovered it was a factory recall and apparently a hub problem, they simply thew a stiffer spring in it. they put me off until it was out of warranty saying it was ok then once out of warranty didn't want a bar of me.

Interestingly the gearbox died just out of warranty (syncro's were shot and bearings stuffed) and upon dropping the gearbox oil it was discovered atf fluid was thrown in it. Bastards..

'The great great guys they were indeed'

The extended warranty I purchased with the car was not 100% honored as they stated the failure was caused by the use of atf fluid. So I had to shell out for half of the repair. ;)

it much oil can make it hard to change gear.. no matter what viscosity (sp) it is.

Thankyou for that - there is nothing wrong with my syncros! to have the oil of the gearbox AND the transfer fluid is way too much..

Anyways this is not about hard gear selection, tis about the transfer case and pumping fluid into the gearbox!

femno I guess the point is did you fill the gearbox, or did someone put ATF in before hand, and maybe the xfer case has a boring normal leak :P

Maybe its not ATF ?

You may have just drained an expensive amount of Redline heavy / light shockproof gearbox oil !

Just a thought.

Just because its called Redline doesnt mean its red you know!

Does anyone who has replied here even know how a GTR gearbox/transfer arrangement works??

No one but me has touched the car so no, 'someone' hasnt put ATF in the gearbox....

*frustrated*

Um I don't know how the attessa works. I mean, I have only apart one of them, , bleed the system a few times, but apart from that, no, I don't know hwo it works.

I noticed that you joined the forum in March 2005.

I believe the question is do you know how it works?

We're only trying to be nice and help you out with possible reasons for why it might be like that.

Just like diagnosing any other problem, there is a series of steps you go through.

e.g. it is quite plausible that synchros might be worn after 15 years.

Also, redline does have a red shockproof oil.

What does this say abot me that i joined in March 05?? Seriously tell me id love to know. Maybe you could argue the fact that im 18 as well, some young bloke who doesnt know sh!t

And yes indeed i know exactly how the ATTESSA works. I also happen to know that on the front of the transfer it has it own pump and this is where i know it is leaking from, pumping into the gearbox where it fits onto the output shaft.

I have no issues about the operation of the system...jus wanting to know if anyone has had this problem before and where the best place is to go and have this rectified.

Im not having a go at anyone and i know that people are only trying to help me out and this is very much appreciated, thankyou all. But you cant blame me for commenting on the uneducated guesses im getting about this though.

Thanks again,

Mat.

What I was getting at is that you've been on the forums for 1 year.

Duncan has extensive knowledge and plenty experience.

My post above got stuffed up. What I was getting at is that I have actually rebuild a transfer case and bled several of them.

I was just saying that we were merely leading you through a process of diagnosis. I'm not saying that this is you, but many other people haev asked questions like um, ah, like how do I like bleed this etc.

Anyways, don't worry about it. which part is leaking?

Hey Femmidom.

"Then drop the drain plug and even more. Undo the transfer case drain plugs...a drip comes out."

Without the pump running what did you expect ?

I merely mentioned the redline oil because the stuff i bought was red !

Is the Attesa fluid reservoir running dry ?

I am well aware of how the system works and have a spare stripped in the garage.

You should look in the manual under Transfer Oil Seal Replacement !

THE PAGE IS NUMBERED CH63.

Also shows the position of the Pump.

If you dont find this helpfull , I cant help !

Chill Cokey

Note the only reason why people throw ATF into gearboxes that are not spec'd for it is because it improves the shifting quality of a f**ked up gearbox (due to ATF being very thin). Obviously ATF's additive pack is not suitable for gear/hypoid action and thus the box wears out even quicker.

This reflects in Cube's testimonial. Sorry to hear u guys got shafted. ATF is a quick and nasty fix.

"Then drop the drain plug and even more. Undo the transfer case drain plugs...a drip comes out."

I think you are getting confused with the pressure system part of the ATTESSA ie (reservoir in the boot, pump ontop of the diff), and the actual transfer case oil. There should always be oil in the transfer case...same as any gearbox.

No the reservoir in the boot is fine, at its normal level.

Anyway the leak is INSIDE the transfer/gearbox setup. No external leaks as such. The transfer has its own pump to circulate the oil inside of it, like the engine oil pump. This is where it is leaking from. Out of the transfer case pump into the gearbox.

I wont be looking up in my manual how to replace the seal because that is something i dont want to touch, id rather have someone who knows what they are doing fix it, not a 5 min job to take this in and out if u feel me...plus im not 100% its the actual seal, might be something else in that area, but wanna get it done properly.

So anyone know a good place to go to have this prob fixed? People that do transfer cases??

    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
    • You haven't driven many modern cars then have you? Most of them have sfa steering feel with their stupid electric bullshit steering systems.
