gearbox oil leak

Guys,

When I came home tonight and opened the garage to park the 612, there was a pool of gear oil on the floor. I parked outside while I cleaned it up, and after I got the car back in, there was a fresh pool where I'd left the car for only a few minutes.

Any ideas on what the failure is ? Should I have it towed to the shop or top it off and drive there ?

Cheers,
Shiv

The pool btw is slightly north of the right rear wheel.

Here's what I found....

Anybody know if I need the SD3 to reset the shift points if I remove the actuator plate ?

Hi Shiv,
if you remove the plate and you reinstall it without turn on the ignition key (or better disconnect the battery) i think is not necessary the SD3 reset.
But perhaps to remove the plate is necessary remove the gearbox because there are not bolts but studs and nuts, for this the plate want space to remove it, i don't know if there is this space from plate to the chassis.
Terry can confirm or correct me ....

Thanks Fabio, I will check the clearance in the morning. Of course, I have asked Taz many questions, let's see what he says....

Shiv, Fabio- I am not sure whether there is F1 fluid or transaxle fluid under that plate. This is one where you probably need a pro to answer. If it is transaxle fluid, there will be no need for an SD3 bleed and actuator recenter and test run. Surprising if there is no gasket there.

Roberto at Roselli foreign car confirmed that it is transaxle fluid and its a non sd3 fix and very common.

Fabio, looks like clearance is not an issue.

Ciao Alex,
I have an 575 and i know how is built, the table I have extracted is from 575 spare parts manual, in past i had a 550 and I have revisioned the gear box (pratically like a 575 gear box) by myself on my workshop.
I imagine you have a Scud?
Where do you live?

Fabio,

What material did you use for the gasket ? I am going to be using Yamabond 4 after the recommendation from the pro. The Arexons 2144 specified by the factory obviously doesn't work well, even if you could find it. Gear oil with friction modifiers is quite corrosive to silicone. I'm also going to fill with Redline 75w-90 LSD.

Thanks,
Shiv

Hi Shiv,

Are passed 5 years .. I used loktite 510, reccomended from Maserati for the engine block, that I had remained from a maserati biturbo that i had revisioned.
For the Yamabond 4 i think is well !!

Yes, I've seen that. But the Yamabond has better high temperature characteristics allegedly, as does Loctite 5810.

OK guys, the car is fixed and no SD3 is required. You have to be very careful with the actuator on the newer cars because they are on a pin instead of a fixed arm and the actuator can get misaligned. We had to do it twice because after the misalignment the car was stuck in neutral. But all is well now. Thanks again to Roberto @ Roselli.

Shiv- Good you had someone who knew how to get the actuator aligned. Normally, the actuator is removed when the fluid is changed and the system is bled, so good to know how to align it.
