Fill Transfer Case Through Gearstick

[Robert Knight]

Hi all, I am about to change all fluids on my 33 GTR and have spent 2 hrs trying to get definitive info on how to access the filler hole for the transfer case through the gearstick,I need detailed info on how to remove it without damaging anything,sorry it seems there is info on this but I can't find it could sks please tell me how this is done and also how to best remove and replace coolant fluid as well and what coolant most gtr owners are using Thanks in advance,Greypearl

Pouring oil through the shifter will only fill the gearbox. There is a seperate drain and fill plug on the transfer case to change the transfer case oil. You will have do get under the car to do this and have some method of pumping the oil in to the transfer case.

Tim is wrong. On a GTR (or I guess any awd RB) you can fill the transfer case via the shifter hole but you should probably locate and remove the filler plug on the side of the transfer case as well so that you can tell when it is full.

Fair enough. I haven't worked on a GT-R, but being a mechanic, I have worked on countless 4WD's and they were all setup this way. I stand corrected.

On a GTR the rear extension housing and transfer case are sealed separately from the gearbox.

Main box uses gear oil, transfer case uses ATF.

So although you could fill the transfer case via the gearstick (which is mounted on the extension housing), you still need to remove the level plug to fill to the correct level.

NEVER drop the oil until you've checked that the level plug can actually be removed.

Often times a careless previous owner has ruined any chance of removing them.

To me, pumping the oil in via the level plug is far easier than removing the gearstick trim, gearstick and so on.

See what I mean info that's reliable is hard to find on this topic,so from what's been said so far I assume that there is a fill and drain plug on the outside of the transfer case but it's difficult to get the oil in so people choose to take the gearstick out to fill it and use the filler hole on the side of the case to know when it's full, so you still have to get both plugs undone on the outside so maybe save the hassle of pulling out the gearstick and use a sludge pump to fill from the outside of the case, but that said I still would like to know how to take the gearstick out properly and find the filler hole, Cheers Greypearl.

Info is in the workshop manual.

Filling via the gearstick was a last resort in the conventional (RWD) gearbox if the filler plug was butchered.

A few 32 & 33 GTR owners have come unstuck thinking they were filling the mainbox via the gearstick.

Thanks mate,So it all hinges on whether you can undo the plugs first and have a suitable pump,last time I did it I did it all from the outside with a sludge pump,new one of course and it was quite laborious then I read about filling the transfer case through the gearstick and thought maybe I missed the transfer case oil change last time and was a bit worried but now I'm more worried that I put the wrong oil in the transfer case as I don't remember buying any ATF fluid yikes may have put smurfs blood in there cause I tried that in the gearbox found it didn't let the synchros work properly as it was too slippery and also since then had the gearbox rebuilt by Award gearboxes in Sydney to upgrade to Series 3 specs and am now going to use Redline MT90 for it's first change since rebuild,I am not sure whether the Transfer case is part of the gearbox so don't know if it got recoed or not as to whether the right oil ended up in there so all will be revealed in 2 weeks will post up my discovery here when I know thanks for your help,but no-one answered the question about how to remove the Gearstick properly or which coolant to use and how to best drain and refill it,Cheers Greypearl.

Transfer is separate to gearbox so that wouldn't have been recoed unless specified. As you've worked out, just drain and fill through the external plugs. But if you need to take out gearstick.

Take off gear knob, pull out ashtray, could be a screw or 2 behind there, now you remove plastic surround, remove boot, now you should see a couple of big circlips holding the stick in the top of the box, pry out the big one on top. Now stick should just slid out.

The right stuff to use in the transfer is Nissan Matic-D. It's about $70 for 5L from Nissan. So you'll get a couple of changes out of it.

Thanks Tricstar at least I know how to remove the stick now thanks to you,,could you tell me the best coolant to use concentrate or premixed,I'm leaning towards Nulon green 5yr stuff what is everyone using?? Cheers Greypearl

[tricstar]

Yeah any good quality coolant will do the job. I've used the Nulon and redline concentrates before.

Cheers Mate appreciate the help,Greypearl.
