Hey guys,

Dont have a R32 manual and wasnt able to find anything about it here in the forums...

So anyway, I am in the process of removing my gear box (32 gtr box) from my R32 GTS4. First time ive ever done this so need a bit of help on 1 or 2 things. The motor is already out so i dont have to worry about the bell housing side of things. Tonight i removed the shifter, then inspected the underside and then disconnected the clutch fork and slave, after that i removed the drive shaft from the transfer case to front diff. Then it started to get a little cold tonight so i am leaving the rest for tomorrow. Before i packed up though i noticed of coarse the speedo cable had to be disconnected, the tail shaft needs disconnecting and im aware there are supposed to be 2 plugs attatched somewhere... 1 is the reverse sensor and im not sure what the other one is supposed to be.

from my knowledge, that is all that needs to be disconnected EXCEPT for a hose i noticed. It connects to the tail of the gear box, about 1 inch directly above the gearbox to tail shaft universal joint. I'm not sure what its for, it was very dark tonight while i was working on it, so i tried tracing it back as far as i could, and it got to a point where i couldnt fit my hands any further. It appears to me like it connects to the rear diff? im pretty sure there is some sort of oil thats going to piss out everywhere if i pull this off?

Really i wanna know, what it is, and the best way to go about removing it without making too much of a mess :cheers: This way i can hopefully get the box out tomorrow before lunch time.

Thanks guys

On a GTR im pretty sure that line leads back to a hydraulic fluid reserve tank thats in the boot for the attessa. So I am guessin it will leak once u open it, best thing to maybe do is get a line lock and clamp the hose off before opening. U will lose a bit of fluid when u pull out the hose but it wont continue to keep falling out with the line lock clamping the hose....

You will probably have to bleed the whole system once u put it all back together as well.

Hopefully ur tail shaft bolts wont be as tight as mine were!!!!!!!

good luck with it all

yea ill have to follow that line more carefully in the sun light tomorrow. Might just bleed the attessa if thats where the hose actually leads, then take the hose off an aim it into a bucket to catch whats left. Yea i hope they arnt tight too.... ive had all sorts of trouble with my engine conversion project regarding tight bolts... especially on the turbo area :cheers: the bloody things snap so easy!

Yeah on the GTR that line goes to the hydraulic pump which sits on top of the diff cradle that runs the 4WD, removal will require rebleeding of the system which is not to hard, you'll have to get more fluid from nissan as it runs a special auto fluid, the other plug im fairly sure is for the neutral sensor. :cheers:

Its the attessa fluid , you will have to undo it and block the end of the pipe , don't worry blocking the gearbox side of it ( very little fluid will come out from there ).

When you re-install the box you will have to bleed the system otherwise your attessa will not work.

ok cheers guys. So besides the hose from the hydrolic pump (located above the rear diff cradle), to the tail of the gear box, where else should i expect to find attessa fluid lines? sump diff at the front? It's just that i gotta start putting this all back together soon an the information the better :D

nope just the hose at the rear of the gearbox. sounds like you've got everything else under control.

When you refill the attessa line use good quality ATF you don't need to use the nissan stuff in particular. One thing to watch out when you bleed the attessa - there are 2 bleed nipples, one at the gearbox and another up on top of the diff.

i have a SAU post saved somewhere on how to bleed the attessa. Looks like its time is near to come in useful for me. ATF or genuine nissan.... Hmmm... I dont know the prices yet... but my bet would be that im going to go with the ATF in the end, for the reasong being that nissan never fail to suprise me with the price tags they slap on thier products... Ill do my homework on the quality between the 2 and go from there.

      Meanwhile, 20+ years ago, I pulled out the 105mm hole saw and went straight down through the inner guard in front of the airbox to get my stormwater pipe cold air intake in. Right behind the two stock holes for the intercooler pipes. Those have no reinforcement (apart from a couple of robust pieces of steel pipe through them!). I feel that the Australian vehicle standards crews put way too much emphasis on "maintaining the crash performance" of cars and not enough consideration of "any crash is a new and wonderful experiment with a random selection of parameters and you will never be able to tell if an extra 80mm hole through some sheet metal caused a significant difference...but if you close your eyes and squint at the whole structure, engage your engineering brain and have a good think about it, you'd have to expect that it would do jack all."

      You guys are focussing on the wrong part of this post and have headed off on an irrelevant tangent!  Clearly I'm not going to put my most prized physical possession (well it will be once I'm finished it...) on a piece of shit contraption that might fail and crush me or my car!  At no point was that even implied I was trying to buy a butchered P.O.S that some shonky clown had thrown together with a gasless MIG....  Either way I would love to see the build quality of a rotisserie that has failed.  Actually I'd love to see a photo of one that has failed full stop.  Google fails to deliver.  Never happened?? I'll either make one that won't fail or will buy one that wouldn't fail! End Post.....

      Yeah, if you can't breathe for more than about 2 minutes, you're cooked.

      Troubleshooting - motor wont turn over

      By GTSBoy · Posted

      Well, all the power should be getting dissipated across the starter motor. Therefore, ideally, the voltage drop across the earth lead should be convincingly close to zero. Certainly you'd want it to be only a volt or so at max, because otherwise that volt doesn't turn up at the starter to do what is required. A car can probably survive a bad enough earth to crank and start with only 9V or so at the starter motor, maybe even a bit less. But you're seeing only 8V at the battery terminals when cranking, so there can't even be that much available over at the starter, which simply won't do. I would have thought that you couldn't pull enough current (with a healthy starter) to make the battery drop to 8V locally. But I was ignoring the possibility that the starter is in fact crook. If it has shorted windings (or maybe the solenoid is borked and shorting to earth) then I guess it could pull a stack of current and not even look like wanting to turn over. So follow the other boys' reccos too. Because they are just as likely at this point.

      Depending where the whole gets drilled, and what country/state you're talking about, quite likely not.   Under ole vehicle mod rules in NSW, VSI06 allowed for drilling of holes in "non structural" areas. So you could drill a hole through the inner guard, and not need engineering. You couldn't drill over seams, and it was advised to add extra reinforcing around the hole, as well as something to protect from sharp edges.   Again, it's all about finding the documentation for where the mod is to be done, AND then being able to explain the situation, with the documentation as to why you don't need engineering, with a positive attitude, to any one of the likes eg, police, vehicle inspector, etc.
