Atf In My Gearbox

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....

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 !

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.

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??

      I had 3 counts over the last couple of weeks once where i got stranded at a jdm paint yard booking in some work. 2nd time was moving the car into the drive way for the inspection and the 3rd was during the inspection for the co2 leak test. Fix: 1st, car off for a hour and half disconnected battery 10mins 4th try car started 2nd, 5th try started 3rd, countless time starting disconnected battery dude was under the hood listening to the starting sequence fuel pump ect.

      This. As for your options - I suggest remote mounting the Nissan sensor further away on a length of steel tube. That tube to have a loop in it to handle vibration, etc etc. You will need to either put a tee and a bleed fitting near the sensor, or crack the fitting at the sensor to bleed it full of oil when you first set it up, otherwise you won't get the line filled. But this is a small problem. Just needs enough access to get it done.

      J50 clock date suddenly reset to January 1

      By suko · Posted

      The time is always correct. Only the date is wrong. It currently thinks it is January 19. Tomorrow it will say it is January 20. The date and time are ( should be ! ) retrieved from the GPS navigation system.

      Buy yourself a set of easy outs. See if they will get a good bite in and unthread it.   Very very lucky the whole sender didn't let go while on the track and cost you a motor!

      Mistakes were made, my R34 Story

      Well GTSBoy, prepare yourself further. I did a track day with 1/2 a day prep on Friday, inpromptu. The good news is that I got home, and didn't drive the car into a wall. Everything seemed mostly okay. The car was even a little faster than it was last time. I also got to get some good datalog data too. I also noticed a tiny bit of knock which was (luckily?) recorded. All I know is the knock sensors got recalibrated.... and are notorious for false knock. So I don't know if they are too sensitive, not sensitive enough... or some other third option. But I reduced timing anyway. It wasn't every pull through the session either. Think along the lines of -1 degree of timing for say, three instances while at the top of 4th in a 20 minute all-hot-lap session. Unfortunately at the end of session 2... I noticed a little oil. I borrowed some jack stands and a jack and took a look under there, but as is often the case, messing around with it kinda half cleaned it up, it was not conclusive where it was coming from. I decided to give it another go and see how it was. The amount of oil was maybe one/two small drops. I did another 20 minute session and car went well, and I was just starting to get into it and not be terrified of driving on track. I pulled over and checked in the pits and saw this: This is where I called it, packed up and went home as I live ~20 min from the track with a VERY VERY CLOSE EYE on Oil Pressure on the way home. The volume wasn't much but you never know. I checked it today when I had my own space/tools/time to find out what was going on, wanted to clean it up, run the car and see if any of the fittings from around the oil filter were causing it. I have like.. 5 fittings there, so I suspected one was (hopefully?) the culprit. It became immediately apparent as soon as I looked around more closely. 795d266d-a034-4b8c-89c9-d83860f5d00a.mp4       This is the R34 GTT oil sender connected via an adapter to an oil cooler block I have installed which runs AN lines to my cooler (and back). There's also an oil temp sensor on top.  Just after that video, I attempted to unthread the sensor to see if it's loose/worn and it disintegrated in my hand. So yes. I am glad I noticed that oil because it would appear that complete and utter catastrophic engine failure was about 1 second of engine runtime away. I did try to drill the fitting out, and only succeeded in drilling the middle hole much larger and now there's a... smooth hole in there with what looks like a damn sleeve still incredibly tight in there. Not really sure how to proceed from here. My options: 1) Find someone who can remove the stuck fitting, and use a steel adapter so it won't fatigue? (Female BSPT for the R34 sender to 1/8NPT male - HARD to find). IF it isn't possible to remove - Buy a new block ($320) and have someone tap a new 1/8NPT in the top of it ($????) and hope the steel adapter works better. 2) Buy a new block and give up on the OEM pressure sender for the dash entirely, and use the supplied 1/8 NPT for the oil temp sender. Having the oil pressure read 0 in the dash with the warning lamp will give me a lot of anxiety driving around. I do have the actual GM sensor/sender working, but it needs OBD2 as a gauge. If I'm datalogging I don't actually have a readout of what the gauge is currently displaying. 3) Other? Find a new location for the OEM sender? Though I don't know of anywhere that will work. I also don't know if a steel adapter is actually functionally smart here. It's clearly leveraged itself through vibration of the motor and snapped in half. This doesn't seem like a setup a smart person would replicate given the weight of the OEM sender. Still pretty happy being lucky for once and seeing this at the absolute last moment before bye bye motor in a big way, even if an adapter is apparently 6 weeks+ delivery and I have no way to free the current stuck/potentially destroyed threads in the current oil block.
