Removing An 32 Gtr Gear Box From An 32 Gts4

[zertek]

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 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 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.

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

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.
