R33 Gtr Stuck In 4Wd

[PHA71]

Hey just wondering if anyone has had this issue I got a r33 gtr , I just replaced the gearbox and used the same triple plate clutch , I took the car for a drive and when I turn , it making big clunking noise from the front diff and the torque gauge is up near 50 and going up and down depending on how tight I turn , I spent all day trying to solve it but no one has a real answer for it . It has a 1.5 cusco front diff but that shouldn't matter cause it wasn't doing it before , pulled the fuse from the boot and it's gone , checked the G sensor and it's ok . The clutch is making some weird noise now as well when I release it in gear has anyone had dramas with the rear actuator on the back of the transfer case or the little rod behind it not releasing cause when I took it off with ignition off there was bulk pressure behind it . Any help would be great

Cheers

When I had the transfer case rebuilt on my car they re-assembled it wrong and it was locked all the time. Not sure if you had any work like that done.

Eric yours would have been machanical but given his gauge is reading 50+ his is electrical

Go through all the plugs you have done putting the box in and make sure they are right

[PHA71]

Alright will do , nah didn't touch the case just unbolted off the old one on to the new , I'll re check all the plugs again I don't know what other plugs they would have touched .

[PHA71]

Would it still be electrical if the rod at the back off the transfer case is stuck out , it's like it not releasing the pressure , we had bled the shit out of it to make sure there is no air in the line .

[XKLABA]

The fact the gauge is reading 50+ means the pump is running hard so something is making it run

Do not drive it till you figure it out or you will be up for CVs and/or front diff, these are 4WDs not AWD so it's like locking a transfer case in 4WD on a hilux and driving it on the road

[PHA71]

So checked most of the things everyone has said , just wondering on the rear pump apparently there 2 switches or solinoids is one telling to pump the fluid and the other to release the pressure ? And trying to bring up a code but couldn't get one for the 4wd , some one said you had to plug it in somewhere in the boot to bring up the 4wd , does anyone know of this it's doing my head in , if there is someone in bris that knows a shit load about this please let me know , cheers guys

doesnt help but the nissan service manual for BCNR33 has how to diag 4wd system

Had same thing when TPS wires were reversed. Don't know why you'd have this problem after just changing clutch/gearbox. Attessa computer is getting wrong signal from something.

Try this

Under you rear parcel shelf in the boot there is a contoller (box) driver's side. Get a mirror underneath it and you will see an red led. With the engine running and the dash error light on, check the led. it should flash in sequence. like one long flash and some short flashes. Note them down and look up the error. If its one of the TPS type errors it likely to be a ground or the power cable off your starter motor check that first. Also look at the connector of you gearbox loom that runs above the front drive shaft.

cheers

Did you figure out your issue? I’m currently running into the same issues. Only thing different is that I’m not running a rebuilt transfer case. Any info would be appreciated.
