I've been doing fluid changes for years. Today I started the annual service on my 355 I purchased at the beginning of the year from a reputable dealer who had used a reputable independent shop for a major service last November, When I pulled the gear box plug, extremely black gear oil flowed out. I almost didn't do it because I've only driven 500 miles since this, supposed, quality major service was performed. Thank God I'm anal and pulled it anyway !!!! This gear oil hadn't been changed in many years! I have a receipt saying it was changed !! Someone paid for a gear oil change !!!! I have six "toy cars" that I service each year. When I pull gear box oil each year after driving less than 1,000 miles, it looks NEW and the light shines through it!! This is piss poor service and some folks should be truly embarrassed. Total Bull S#%}t !
You tellem skipp. Same reason i do mine. I dont always blame the owners of the shops either they sometimes do not know. You should let them know at least. Be nice. Rubb your ears and say woooosaaaa. Like in bad boys movie.
Three years ago I also pulled the gear box screen filter off my Challenge Stradale after purchasing the car. The car had seen nothing but dealer service. Guess what.....didn't look like it had ever been pulled and cleaned. These are high performance cars that need this stuff done !!
The underpanel and bumper has to come off to do a proper service and get to the gearbox screen. I've seen "dealer serviced" cars where that time-consuming step had apparently been skipped. Don't be fooled into thinking that a million $ building with a big sign guarantees that someone knows what they're doing. Ferrari also neglected to include a change interval for coolant so it's possible that it's ancient (and corrosive) as well. I recommend annual coolant and gearbox oil changes, especially after seeing what happens when the heat exchanger (common to 355 & 360 models) fails.
You said it was contracted out by a dealer to another business for the service? That is very common and reflects far more on the seller than the service facility. They want the cheapest possible job so as not to cut into the profit and typically misrepresent the actual service done. Micromanagement of every step is the norm and cheap, cheap, cheap are the guiding principals. That is why I do not and will not have a business relationship with a car dealer. It is also why I suggest strongly not to get servicing built into a purchase deal.
Seems strange to me that the gear oil was black. I've never encountered that in a trans or rear end. I've been told that black gear oil indicates engine oil (or other contaminate?) getting into the gear box. Can that happen on a 348/355? I know it can on a 3x8 when the shift shaft seal between engine sump and gear box fails.
I do. I'm not looking to give anybody a bad name, just letting folks know why it's important to be very vigilant.
Just drained block and radiators as well as engine oil. At least coolant and oil looked clean. I guess you HAVE to do those when the engine comes out !
Engine oil can certainly get into the gearbox. I had a rear main seal failure and no oil leak. Engine oil went low, trans overfilled and leaking from vent. My indy put dye in engine oil after changing both and dye showed up in trans. Rear seal was bad.
Good to know. Thanks for the comment. The engine oil still looked relatively clean. I'm going to flush the gear box and then do it again after a couple hundred miles to see if it comes out clean as I suspect it will.
That was what I was thinking for a 355, but wasn't sure. From my experience if the trans oil was black when drained I would suspect such a leak.
Engine oil level has been fine, so in my case I think the gear oil was simply dark from neglect. I witnessed the same when changing the gear oil in my 930T upon purchase. Some owners and dealers simply don't do what's required. End of this story.
Id love to see a photo of the oil just to see how bad it was. Could it be contaminated? Sure but as said earlier someone with a rear main leak can leak into the gear box, the gear box only has a big oring to seal that huge hole in the trans, It will catch oil with no problem in that situation. There is no secret that plenty of business with cars are more than happy to charge you for a service IE service records yet nothing was ever done! One reason I don't put to much trust in service records they can be pencil whipped as I like to call it.
Didn't take a picture, but if the engine oil had leaked into the gear box, it should have been all the same color. It was not.
I just drained the diff fluid on my wife's 130k mile X5 and it looked like golden honey still. Almost same results from the ZF 5 speed transmission in my M3 with 150k miles. I've never encountered a gearbox or diff with truly "dirty" looking fluids before and I've had many vehicles and most of them between 100k-300k where there is more wear present. Combustion in an ICE causes the dirty oil look, otherwise engine oil would visually look the same after a full cycle. Not discrediting or anything, but that just sounds off.
It's not about how many miles your car has, it's about the frequency of the changes. All mine get changed annually and they look golden too. I've certainly seen personal vehicles that had very dark gear oil when I bought them because others had not changed the fluid. After that the car had clean looking fluid every year thereafter because I changed it annually. I expect this will be the same. You'd be surprised how little care cars get from non car guys. I've had Porsches, Alfas, and now this Ferrari that have had dirty gear oil because nobody changed it for years !!! In fact, 80s Porsche 911s had a 60,000 mile gear oil change interval. Maybe would get changed every 6 years ! It's really only Ferrari owners that over service there cars.
I was able to re-flush the gear box today after driving the car about 300 miles in the last couple months. The fluid came out totally clean. My initial thoughts were correct. The black gear oil that came out two months ago was simply very old and the shop that did the major last year failed to change the gear oil. I'm very glad that I decided to flush the box even though it should not have really needed it this year. You never know what you're going to find after someone else "services" your car. Very glad there was not a rear main seal failure, just poor work ethic.
