599 Gearbox oil and F1 system oil

Well an f1 system is an automated manual so the same would apply

 

F1 system oil is separate from gearbox oil- its different fluid doing a different job, so no reason to expect it would be on the same schedule as F1 fluid.

575 and 612 workshop manuals have gearbox oil on a 2 year interval, which does seem a touch excessive for the mileage most people are doing. Interestingly I went through the 599 manual, which uses the same gearbox, and they don't seem to mention any scheduled gearbox oil replacement.

 

My handbook says change gearbox oil at 37500 miles and 75000 etc

 

Here it is. Every 3 years or 37,500 miles, as stated above. F1 fluid, too.

Any 75W90 transmission oil will do if Shell is unavailable.

 

Generally I agree. People here generally WAY overthink this stuff. Yes, a good quality oil but seriously. Drive it and have fun.

 

GL5 additives destroy yellow gears, so this is bad advice.

 

You are right. My bad wording for which apologies. What I meant was any 75W90 oil to same spec as Shell. Previous discussions here have gone for Motul Gear 300.

 

There are many LONG LONG threads here debating the pros and cons of GL4 vs GL5. Honestly, they never reach a consensus because both have advantages and disadvantages.

 

Dick- Choice between synchros and rear end. No clear winner and Ferrari recommends GL5. Not cut and dried by any means.

 

It's reasonable to assume that the Shell TF 1055 Ferrari transaxle oil has the correct additive balance, despite it being GL5. As you said, there's no clear winner. Using a random GL5 oil to save a few dollars is idiotic.

The Shell Spirax S5 ATE 75W-90 should be fine for the F1 Graziano transaxle, even though it's for the Getrag DCT.

 

Synthetic GL-5s work fine if you cannot find the Shell product. Theoretically all GL-5s meet GL-4 specs, too, just with different additives to make them work on hypoid gears, some of which are not friendly with copper based synchros.

 

I just replaced mine with Motul 300V and gear changes are smoother, no idea what was in it before or when it was change last.

 

my dealer wont replace the f1 fluid for the actuator (hydraulic) they say leave it as it can cause issues

 

Michael- Find someone else to service her. Hydraulic fluid wears, gets dirty, absorbs water, etc. That is why we change brake fluid frequently. US 599 maintenance schedule:

My advice would be to find a new service provider.

 

I totally agree that the fluids must be changed per Taz's chart or even more often. These cars have pumps that stress/wear both fluids. My 8Kmi 599 had dark gear oil and F1 fluid. The job is somewhat involved because the F1 reservoir is very hard to access, the transaxle must be raised off of the mounts to get the gearbox screen out, the cooler lines must be disconnected and cleaned and the cooler should be removed so it can be properly cleaned out. I do most of these types of jobs myself and have the tools and scanner, but gladly paid about $1K to a great indy in Naples to do the work.

 

As described, use a turkey baster to pull out a bunch of fluid. Then refill and drive a bit. Then do it again. After a couple of rounds it will be almost completely new fluid.
