TUF250 Posted June 17, 2010 Share Posted June 17, 2010 Hi all, I have an R33 GTS-T with 87,000ks The gearbox was a little notchy when I bought it so I did a service as recommended on this site with the castrol VMX 80. I also used the Nulon anti wear additive. It has improved all shift and noise but the box still has a nice notch into second until very warm, dosnt usually crunch (has happend once I think?) Is this normal for one of these? or is the box screwed? Would using the redline shcokproof stop the notch for a while? Where do you buy this redline stuff and what weight is recommended? look forward to peoples thoughts Link to comment https://www.sau.com.au/forums/topic/325278-will-redline-shockproof-hide-this-problem/ Share on other sites More sharing options...
Wacky Dee Posted June 18, 2010 Share Posted June 18, 2010 my 34 has a notchy shifter (1st 2nd only) when cold and I've put that redline stuff (shockproof/smurfs blood) and I'm not sure it has improved anything... If you intend to be keeping the car for a while I'd say save up some dough and get the gearbox and synchros reconditioned for teh win.

R33 Sleeper Posted June 18, 2010 Share Posted June 18, 2010 Hey mate, i had exactly the same situation, bought the car when it had bout 85000k and gearbox was pretty stiff from 1st to second when cold, got redline in there now, still noticeable for the first few shifts but much better than before!

lotsalag Posted June 20, 2010 Share Posted June 20, 2010 rb boxes r often notchy when cold, just take it easy. lightweight might help a bit no experience with it. heavyweight is rubbish for the gearbox, i dumped the oil after a week! maybe try motul fflsd 75/90+nulon additive i've used it many times on customers cars and my own see how ya go, if its synchros stuffed, nothing can bandaid that Link to comment https://www.sau.com.au/forums/topic/325278-will-redline-shockproof-hide-this-problem/#findComment-5302948 Share on other sites More sharing options...
snozzle Posted June 20, 2010 Share Posted June 20, 2010 (edited) redline will help the problem but give valvoline super synth 75w90 a go, its only 50 bucks, i had a crunchy 2nd gear in a past car, dumped the vmx80 out of it, changed it to 75w90 valv, still kinda notchy wen cold but after 5mins, it was perfect vmx80 made it crunchy wen cold and notchy wen hot some boxes love vmx80 though, it all depends on the condition of the box, different boxes like different weights, that is why you will often find people will have different views on oils, especially with gearboxes edit: i just checked out that site, very cheap pricing on the redline oils, i will order some smurfblood for my gtr the prices on that site are almost half the price of redline products i see on shelf at shops in perth!

TUF250 Posted June 21, 2010 Author Share Posted June 21, 2010 yeah the vmx80 was great when it went in, note I used the nulon g70 too but its gotten worse again. Very stiff when cold, only into second and not that flash wehn hot either, i might try the redline and see if it makes a difference do you use the nulon dditive with the redline shockproof?

gfunkk Posted June 21, 2010 Share Posted June 21, 2010 i hear so many mixed opinions about smurfs blood, i was talked out of using it at one stage apparently its good for smooth shifts but causes more wear in the gearbox?

Blue Posted June 22, 2010 Share Posted June 22, 2010 I recently pulled apart an R32 RB25DE box with pretty low kays on it as I had it in my track car, the box is smooth and quiet and everything worked nicely except that once it was nice and warm the top gear synchro stopped working. In a nutshell, while the synchro wear was within factorly limits, it just did not work when it was hot and different oils made no difference. I change dthe top gear synchro ring and it now works perfectly, the only problem is that now the other four feel tired comapred to it including the standard notchy shift from first to second. Someone mentioned that RB boxes are pretty well known for it, I would go further back than that, it is fairly typical of Nissan and Datsun boxes in general. So long as it is only noticeably notchy when it is cold I would just go easy on it and worry about it if the synchro gets batty when it is hot. I plan to pull my box down again later this year and replace the rest, along with having a look to see if I can swap the top gear with my other box, which is an R31 RB20DET box and has a shorter top gear ratio that is much more suited to track use.

Ultimategtr Posted June 22, 2010 Share Posted June 22, 2010 @ OP - I had same issue.. notchy going into 2nd(upshift or down). Redline shockproof lightweight did the trick. I used some additive for the gearbox as well - Cant remember the name tho.

TUF250 Posted June 22, 2010 Author Share Posted June 22, 2010 ok I have ordered the oil. Ten out of ten for customer service from harols (the website recommended above)! just fantastic. Oil should be here tomorrow. Now here is my question. I have vmx 80 with the g70 additive in the car now, has been there for about 1500ks. Apparently the g70 reduces friction and causes the syncrhos not to engage. If I drain the oil overnight will it get all the nulon out or do I have to flush it? If I drain it will the little bit of nulon left upset the redline oil? thoughts would be appreciated, just such a pain to drain it, dont want to do it more than I have to if it can be avoided thanks Link to comment https://www.sau.com.au/forums/topic/325278-will-redline-shockproof-hide-this-problem/#findComment-5306157 Share on other sites More sharing options...

Ten Four Posted August 22, 2010 Share Posted August 22, 2010 Another up for Harold, bought loads for my old R32GTR through him. OP, assumed smurf blood fixed your problem and redline is the god? PS, it also fixed my mates 33GTR problem of grinding into 5th.
