Hi guys i have a gts4 with a full gtr gear box swap in it. The problem that im have is it isnt gripping in the front wheels like another box i had in there was graping (front wheels) prior to this one.

Is it possible that it needs to bleed up more. I bleed up until i saw no air, but this was from the back of the box and i know theres another spot by the motor on top the diff. Do you guys think this would cause a problem.?

Next is it possible to rebuild the transfer case as i dont mind doing it. Do you guys know of any threads here that has a step by step rebuild procedure just as a reference to follow.

Also whats the best place to find the replacement disks for the transfer case.

Thanks a million.

Do you have a gauge and is it showing torque being sent to the front etc?

If not, likely bleeding issue - seems the most common.

But yeah, if you haven't got the g sensors right (or even if they are not working) that can also cause it

Well all the electronics stayed the same all i did was change the gear box. Today i bleed both spots on the pump and the actuator on the rear of the transfer case. I have two different tires on the front. I ordered 4 of the same tires and will test it after they arrive. Last time i had all the same tires on the stock wheels and it seemed way more aggressive. I am noticing the gauge moving, its just not moving as much as last time. If the g sensor is disconnected wont the 4wd light come on. Thanks for the reminder. Ill check that cause i did have some of the wire disconnected to remove the torque split controller. Cant remember if it was plugged back up. I would figure the 4wd light would come on if that was disconnected???? The car i took the box out of only had 84k on the clock anf was always stock not even a boost controller in it.

Thanks for all the suggestion guys ill check that g sensor tomorrow first thing.

I can understand that. But i had the car set up the same way before the accident. Well just to add im using all the gts4 electronics. The only thing i can think of is i used the front suspension off the gtr because the gts4 wheel bearings were damaged. I would guess the front speed sensors are the same. As the drive shafts were.the same. Thats about the only electronics that was changed. I used the complete front suspension from the r32 gtr.

Did you check the wear on the attessa clutch plates before you installed the box?

:wacko::wacko:

No i just installed the box:wacko:

This why i was looking all over for a thread on the transfer case because i have 2 more and was wondering if i can stack another friction plate in there. I dont see it to hard to do.

I just cant find hard evidence of if its possible and what the results would be like.

Well yes, "sticking an extra friction plate in there" is essentially how you modify them for more front torque, just like tightening up the mechanical diffs.

I suspect there is a little more to it than just throwing an extra plate in as far as getting measuring and getting the right amount of forward drive without locking it up all the time, but if you understand how much extra you need then go for it!

If you look up the manual there is supposed to be a certain amount of clearance (for want of a better word) beyond the last plate. You measure this and shim the clutch pack to suit. A worn pack will have grater than acceptable clearance - the result is that the attessa system doesn't function properly because there is not enough force on the friction plates. The system displays the output on the dash - the output of the pump basically, not the torque output - it is too stupid to realise the clutch pack is worn. End result is the gauge wont help you diagnose a worn clutch pack, only a vernier will.

    • Yeah, the latter. No diff should have a centre replaced without checking clearances because its unlikely to be the same as whatever came out. Not that that stops most people just checking a new centre in
    • Major thread necro but how bad of a job is it to DIY? Looking at it online it looks like if you reuse your ring and pinion as long as those are in good condition it should be fine to just pull the axles/front cover and replace the diff that way? Or should I be replacing everything and doing preload measurements/gear mesh testing like the factory service manual mentions for the rear diff?
    • in my list I had the R33 GTR as the best Skyline. Infact I had all GTR's (33>34=32), the NSX, the GTO, the 300ZX, the 180SX, the S15 better than the FD RX7. I had the MR2 and the A80 as 'just' better. I also think the DC5R Integra looks better but this is an 01 onwards car. I also think the FC>FD. It's almost like aesthetics are individual! The elements @GTSBoy likes about the FD and dislikes about the 180 are inverse in my eyes. I hate the rear end of the FD and it's weird tail lights that are bulbous and remind me of early hyundai excels. They are not striking, nor iconic, nor retro cool. The GTO has supercar proportions. I maintain these look much better in person (like the NSX) especially with nice wheels and suspension which is mandatory for all cars pretty much. Some (or all) of these you have to see in person to appreciate. You can't write a car off until you see one in the flesh IMO. Like most people we probably just like/dislike cars which represent certain eras of design or design styles in general. I also think the 60's Jag E type looks HORRIBLE, literally disgusting, and the 2000GT is nothing to write home about. FWIW I don't think the Dodge Viper Gen1's have aged very well either. You can probably see where I rate bubbly coupes like the FD. I know we're straying now but the C4 and C5 absolutely murder the Viper in the looks department as time goes on, for my eyes. Wouldn't surprise me if people who love the FD, also love the MX5, Dodge Viper, Jag E Type, etc etc.
    • I used to hate R31s, and any of the other Nissans that led up to it, and any of the Toyotas with similar styling, because of the boxiness. They were, and remain, childish, simplistic, and generally awful. I appreciate R31s a lot more now, but only the JDM 2 door. The ADM 4 door (and any other 4 door, even if they are unique compared to our local one) can eat a bowl of dicks. The Aussie R31 is also forever tarnished by their association with stereotypical bong clutching Aussie R31 owners of the 90s and early 2000s. I think the Nissans of the 70s (other than 120Y/180B/200B) are far superior looking to the 80s cars. The 240K era Skylines are boss. The same is broadly true of Toyotas. Hondas don't ever register in my thinking, from any era. Mitsus are all horrid shitboxen in any era, and so also don't register. Subarus are always awful, ditto. Daihatsus and Suzukis also don't generally register. They are all invisible. I think the SW20 MR2 looks fiddly. The 3000GT/GTO is like that but way worse. Too many silly plastic barnacles and fiddly gimmicks ruined what could have been a really nice base shape. Kinda-sorta looks like a big heavy ST165 Celica coupe (and I'm not sure if that's a good thing or a bad thing). I think the 180SX is dreadfully bland. It's not bad looking. But it has no excitement to it at all. It's just a liftback coupe thing with no interest in its lines, and bad graphical elements (ie wide expanses of taillight plastic on the rear garnish). The S13 Silvia is a little better - getting closer to R32 shapes. But still....bland. S14? Nope. Don't love it. S15...a little better. Probably a lot better, actually. Benefits from not being like a shrunk in the wash R34 (where the S13 was a shrunk in the wash R32 and the S14 looked like a Pulsar or something else from the stable on Nissan mid 90s horrors). The Z32 was hot as f**k when it came out but hasn't aged as well as the A80. Keep in mind that I think the R33 is the most disgusting looking thing - and out of all the previous cars mentioned is objectively closest to my precious R32. It's just....real bad, almost everywhere you look. And that is down to the majority of what was designed in the 90s being shit. All Nissans from that era look like shit. Most other brands ditto. In that context, the FD absolutely stands out as being by far the best looking car, for reasons already discussed. Going behind the aesthetics, the suspension alone makes it better than almost any other car.  
    • If they just called it the "Mazda Tiffany", it would have been spot on.
