Gtr34 Getrag Boxes Shd Use Atf? Extremely Noisy

[rysith]

I'm glad I came across this thread.

Since taking ownership of my R34 GTR (with Exedy twin plate clutch), I have observed exactly the noises that were mentioned above:

On idle, sometimes there would be a loudish clunking noise sounding from the gearbox area and when depressing the clutch pedal the noise would go away. When the car was turned off the rattle would occur as the engine shut off.

I was pretty worried that it was some clutch/gearbox related issue - but now know it is a common fault with this combination of gearbox/clutch.

Also I believe that my mechanic may have used Redline fluids in the past, so I'll pass this info on and get some of the Castrol Transmax Z or Nissan Getrag Gearbox fluid for future use.

Ive been using redline shockproof oil (smurfs blood) in all our gtr boxes including the getrag whores.

Forsome what of over 8 years now and i cant stress how much i have never had a problem with this oil .

Atf is what they reccomend , but i have seen it destroy high power output cars gearboxes due to the gears breaking through the oil and contacting each other thus heating up destroying the hardedning etc.

I have never seen this with smurfs blood, as the Gears usally break before the oil on the gears is thinned enough for them to contact.

all myths aside, i would not use just normal atf, maybe the one they reccomend But i can not stess enough that redline shock proof is the only way to go ,

my 2 cents.

Hey guys, is the view on this subject still the same? The bulk of this thread is from 2006, so what are people using in their R34 GTR Getrag 6spd boxes these days?

- Nissan Matic D

- Redline Super Lightweight Shockproof

- Motul Gear FF LSD

- Castrol Transmax Z

- Other?

Cheers,

Ive gone for the genuine toyota v160 atf - damn expensive but how often do u have to change it ey?

[Angus Smart]

Still using Transmax Z... tho probably done 2000km's since then

Both the v160 and Transmax Z ATF's have been discontinued apparently?

The 'box in mine is quite noisy when it's cold. Hard to describe the noise, it's kind of whining (not like straight cut gears).

2500rpm or below, just prodding along until car is up to temp. The noise is usually gone after 5min of driving. Is this normal?

Also i heard a few people say the gearbox rattles when they shut the car off - i had this as well, until i actually engaged a gear when turning the car off. It doesn't rattle anymore.

Ed - We catching up soon or what?

Yeah man, here too! the first 2 gears has a slight whine until it reaches operating temp and the rattle is from the upgraded clutch u have; very common problem which all aftermarket clutch manufacturers mention.

The rattle is annoying bt jst push the clutch in and turn the car off and u wont get it.

hope your car is going well huy, damn beautiful!!

It rattles quite a bit in traffic, but it doesn't bother me at all.

Car is going great, cheers. No problems thus far (touch wood!) All credit to GT Auto Garage for a mint car.

Thought you were selling yours, no?

Not selling mine anymore, wanted too at one stage cos it was my only car but i bought back my e46 BMW and a little getz as my daily's so the GTR stays as my fun/weekend car.

I think that's pretty normal Huy. I don't really recognise it on mine, but my box is generally quieter when its warmed up and it also makes the rattling sound when turning the car off, just like all other Getrag owners. Best to get your fluids checked though as I just changed mine. My Nismo twin plate is not as noisy as I'd thought, which is a good thing.

Yes, catchup soon dude, just busy as with work and stuff...
