wow everyone has stated lots of thoughts since i last checked this post . Anyway i ended up putting Redline 75w90NS in my 360 box and i got to say i am not impressed at the moment. When car is at running temp sometimes the gear changes are some what more harsh than before and getting some stange noises i think from the gearbox maybe this chatter people keep talking about . Even when i am driving between 30-60mph i get strange noises . Dont want to sound silly but can someone explain how what this chatter actually sounds like ?? Also i didnt put any friction modifier in the box is this required?
You feel the chatter form the LSD, you don't really hear it. If you are hearing strange sounds from the gearbox you have some other issue and oil won't fix it.
i am not even 100 % sure if its gearbox or not . If i am driving between 40-60mph you can hear what sounds like humming drone noises , let go of gas it goes way , put gas on it comes back. Had a gearbox rebuild 2 years ago with new 1st 2nd gear syncro plus selector forks etc , also had a new right wheel bearing and just recently i have had the left bearing changed . The car has covered 9000 miles since the rebuild . Anyone have any ideas what could be causing this noise ?
i currently have the F430 exhaust fitted to my 360 with sports cats 200 i think they are . I would never think about it being caused by the exhaust could you maybe explain why it could be ?
Some exhausts particularly after market or exhausts not OEM, can make drone noises at certain rpm. Can't tell unless I were to hear it. Sorry.
Red line 75w90ns GL5 out and MT-90 GL4 in. F430 manual. First impressions, (once warmed up, winter here) the transmission seems a little smoother with a little less effort to shift and I had no issues with shifting previously. No odd noises. Time will tell I guess.
Just spent about 2 hours down at the ferrari dealership hanging out with the techs. I asked 2 techs who have been at the dealership for each over 10 years. Neither of them had ever changed any synchros on a 360. One tech was working on trying to rebuild a 360 f1 actuator while I was chatting with him. I picked up 10 quarts of diff fluid. One of the techs pulled up in modis the ferrari recommended oil for my Scuderia and 360. See attached. I think you guys are out of your minds not using what the factory recommends in the gearbox. I've been using Mobil 1, the tech told me it's probably better I switch back to the shell as they have been using it for years without any trouble. This stuff going into my cars tomorrow.

Remind your techs to tighten all the oil drain plugs to the factory recommended torque settings too. Ferrari, like any manufacturer don't always get it right. Just look at the F430 exhaust mountings and how they simply don't work. I have made several improvements over stock on my car.
Aye, and there's the rub. You are putting differential oil (your diff fluid) in a manual transmission sharing a sump with an LSD. That is what this whole thread was about. If putting the Shell in there makes you happy, go for it. If it makes you feel any better, I do it, too, just do not like Shell lubricants, so use something else.
I have a reply from MOTUL .... Thank you for sending your inquiry pertaining the gear oil as per below. Due to the yellow metal syncros, the required spec is API GL-4. Gear 300 75W90 covers the spec but not suitable for LSD setup, meanwhile Gear 300LS is in API GL-5 (not suitable for yellow metal) with LSD setup. The following products from MOTUL which cover API GL-4 with LSD setup but not in SAE 75W90; 1. 90PA 2. Hypo Synth LS 75W140 I have also attached the PDFs for your reference.

Funny Motul told me something different ..they recommended the 300 for the 430 scuderia Sent from my Moto G (4) using Tapatalk
Honestly, if the oil industry is anything like every other industry - i'd say we will be lucky to actual find anyone within the industry who knows what they are talking about.
Shows what they know. Nothing to do with LSD, at all. The positrac couldn't care less. It's about the EP additives in (GL5) hypoid gear oils that eat synchros.
But they did spot the yellow metal issue and recommend GL-4 over GL-5. Sent from my iPad using Tapatalk
Yes but no. Every single one of those oils they recommend are GL-5. (but they "cover" GL-4 spec) They also claim them to be yellow metal friendly.
Shell Transaxle 75W-90 is still produced and now marketed as Shell Spirax S5 ATE 75W-90 according to a highly reputable UK Ferrari Dealership - who also confirmed to me specifically that the oil is safe for yellow metal/brass parts in the 360 Tx. And further, that this is what they use as their Tx oil. But before I get pilloried, I'm only recounting what a dealership told me.
Yes. The only issue with Shell is the inability to obtain it in quantities small enough for private use.
According to them it does, and it is spec'd by Ferrari. Whether it really does, I don't know. To achieve GL-5 spec, I think everyone uses pretty much the same compounds, and if so, I have a hard time thinking any of the companies can overcome the laws of chemistry. It is possible that the different companies use differing amounts of additives, or other ingredients which have interactions that could defeat or minimize the tendency to tightly bond to the yellow metals and shear off metal molecules, but there's no way the consuming public could figure this out.
