Trozzle Posted August 12, 2011 Share Posted August 12, 2011 Recently changed my manual gearbox oil since the Shockproof that was in there had been there for about 30,000km lol. About 2.8L came out, replaced with about 3.3L of Syn75. Immediately felt the difference - I can barely get it into 2nd gear anymore, even when it's warm. Will also crunch/collide on its way from 1st to 2nd, and occasionally from 2nd to 3rd. SIGH. The next time the oil's changed in this box, it's because it's being rebuilt. Piece of shit. Also disappointed with the oil making gear changes WORSE than when it had 30,000km old Shockproof in it.

Galois Posted August 12, 2011 Share Posted August 12, 2011 Is it worth replacing it with more of the shockproof? Link to comment https://www.sau.com.au/forums/topic/205993-transmission-lubricants/page/5/#findComment-5963551 Share on other sites More sharing options...
Trozzle Posted August 13, 2011 Share Posted August 13, 2011 Not for the price no, it'd be a gamble. Gearbox was fairly iffy as it was even with shockproof...not dropping $100 worth of syn75 just to see if even more expensive shockproof has the same outcome. Shit happens really, gearbox was always on it's last legs with the synchros...rebuild when clutch finally lets go (very soon it feels like lol) Link to comment https://www.sau.com.au/forums/topic/205993-transmission-lubricants/page/5/#findComment-5964262 Share on other sites More sharing options...

R31 POWER Posted August 13, 2011 Share Posted August 13, 2011 Trozzle i had the same problem! I thought i was the only one haha. Had smurfs blood that i thought was old, changed to castrol syntrans or syntrax (the expensive one) and it was shiit. Crunched nearly every gear and was just horrible to dvive. Actually dumped the oil and binned it while putting my old smurfs blood back in which made it all good again!

Trozzle Posted August 14, 2011 Share Posted August 14, 2011 I wouldn't be surprised if putting the smurf back in would fix mine too, but yeah for the cost I just really couldn't be f**ked dealing with it right now lol...obviously rebuilding the box is significantly more expensive, but she'll be good as new then! I'll just deal with it until then lol Link to comment https://www.sau.com.au/forums/topic/205993-transmission-lubricants/page/5/#findComment-5965527 Share on other sites More sharing options...
Owens Posted August 22, 2011 Share Posted August 22, 2011 A bit of a noob question. But what does "smurf blood " consist of? Also, how have people found Motul oil range? Thinking of doing a full change of all the oils soon. So just trying to get a good idea of the best ones to get Link to comment https://www.sau.com.au/forums/topic/205993-transmission-lubricants/page/5/#findComment-5979643 Share on other sites More sharing options...
Trozzle Posted August 23, 2011 Share Posted August 23, 2011 Smurf blood is Redline Shockproof. It's called Smurf's Blood because it's a thick blue liquid lol Link to comment https://www.sau.com.au/forums/topic/205993-transmission-lubricants/page/5/#findComment-5981702 Share on other sites More sharing options...
dori34 Posted August 24, 2011 Share Posted August 24, 2011 has anyone used this on their car? http://www.mobiloil.com/USA-English/MotorOil/Other_Products/Mobil_1_Fully_Synthetic_Gear_Lube_75W-90LS.aspx can this be used in both gbox and LSD or just LSD only?

Moodles2 Posted August 24, 2011 Share Posted August 24, 2011 A bit of a noob question. But what does "smurf blood " consist of? It's a fully synth fluid by Redline, Shockproof Lightweight, effectively a 75w140 gear oil. Uses some special additive to prevent gear crunching (teflon, ptfe who knows) Personally I only use it because the previous fluid I was using (genuine nissan fluid) had a gear crunch between 3rd and 4th at the track, shockproof lightweight got rid of that crunch.

mystery_kid Posted August 30, 2011 Share Posted August 30, 2011 it's not the castrol oil that is bad, it's your gearbox not sure what oil was in my r34 gb when i emptied it but it was being a bit of a prick to get into first and second when it was cold. Replaced it with castrol and it's been silky smooth ever since.

Owens Posted October 18, 2011 Share Posted October 18, 2011 Ok So after much reading, I've I'm most likely going with the following for my '96 GTR - What are peoples thoughts? Gearbox: Redline Shockproof Lightweight Gear Oil - 3.8 Liters Transfer Case: Genuine Nissan Matic-D Transmission Fluid - 2 Liters Front Diff: Redline Gear Oil GL-5 75w90 - 1 Liter Rear Diff: Redline Gear Oil GL-5 75w90 - 1.5 Liters Couple of questions though: 1. I remember reading below mentions "85W-90", but I can only seem to find "85W-140" from Penrite, Redline and Castrol, Is this the same or completely different? 2. Is it ok to use the same 75w90 on the front and rear diff? or would it better to use 80W-90 on front and back? Quoted earlier in thread: Front final drive (page CH-125) - Nissan gear oil hypoid GL-5 85W-90 [approx. 1.0 litre] Rear final drive (page CH-125) - Nissan gear oil hypoid LSD GL-5 80W-90 [approx. 1.5 litres] Link to comment https://www.sau.com.au/forums/topic/205993-transmission-lubricants/page/5/#findComment-6068114 Share on other sites More sharing options...
Galois Posted October 18, 2011 Share Posted October 18, 2011 Might be worth throwing in some nulon g90 (or g70, i can't remember which, one replaced the other) too, it's pretty good stuff.

Moodles2 Posted October 19, 2011 Share Posted October 19, 2011 iirc Redline doesn't recommend putting any additives in their gear oils. Link to comment https://www.sau.com.au/forums/topic/205993-transmission-lubricants/page/5/#findComment-6068668 Share on other sites More sharing options...
Owens Posted October 19, 2011 Share Posted October 19, 2011 Moodles2, what do you put in your front and rear diffs?

Galois Posted October 19, 2011 Share Posted October 19, 2011 iirc Redline doesn't recommend putting any additives in their gear oils. Fair enough. The more expensive oils probably don't need the additives anyway.

Moodles2 Posted October 19, 2011 Share Posted October 19, 2011 I put shockproof light in my front diff (only because i used it in the gearbox), and redline gear oil 75w90 in the factory LSD (didnt want shockproof to tighten up the LSD at low speed) cheapest for redline oils is from performancelub.com Link to comment https://www.sau.com.au/forums/topic/205993-transmission-lubricants/page/5/#findComment-6069510 Share on other sites More sharing options...

Moodles2 Posted October 20, 2011 Share Posted October 20, 2011 Copy and paste from earlier in the thread, you will have quite alot of shockproof left over if only doing both diffs: Front final drive (page CH-125) - Nissan gear oil hypoid GL-5 85W-90 [approx. 1.0 litre] Rear final drive (page CH-125) - Nissan gear oil hypoid LSD GL-5 80W-90 [approx. 1.5 litres] Link to comment https://www.sau.com.au/forums/topic/205993-transmission-lubricants/page/5/#findComment-6070610 Share on other sites More sharing options...
