Transmission noise?

I had it on my car. It sounded terrible on downshifts in auto, almost like the gears were grinding into each other, but went away if I put it into manual mode. It was traced to a software issue. The software was reflashed for an update and since then I've had no issues.

 

What year/delivery month are these two Cali's? No issue with mine, just checking to see if the newer car owners don't need to think on it.

My car is a November '09.

 

I have had a couple of small glitches, which I dismissed. One time I did not get the gear # in the window. Yesterday, I was in 2nd and when I hit the gas, it revved but did not engage.
I upshifted and then it kicked in. I may ask them to do that reflash software upgrade.

 

Not4One and ISUK ... did it work OK if you were in manual mode and let it automatically downshift as you slowed down? Just curious as I am not having the problem.

 

From memory the noise only happened in auto mode and even then it happened only intermittently. The feedback I got from Ferrari's Technical Manager for the UK was that the issue wasn't anything mechanical but was caused by resonance from the hydraulic pump that actuates the clutches.

You'd soon know if your car was affected because as not4one said the noise is loud. As far as I'm aware mine was the only car in the UK to have suffered the fault at that point.

 

I had the same thing happen as well. I thought it sounded like the ABS was activating only louder but without the vibration associated with it.

 

Mines got that noise too - thanks for the pointers.

 

Just rechecked the info I got back about this fault. It was the fluid flow that was setting up a resonance within the gearbox apparently.

 

Hi guys, i too get that "gears grinding into each other" sound, happens in Auto mode when slowing down and taking off from a start, really annoying sound, i just want to make sure if it's ok to drive around with that fault or is it important to check it in for a service cuz it sure as hell looks like i'm destroying my transmission or whatever is making that awful sound, Hope it's a minor fault that can be ignored..

 

I was told it's safe to drive and won't cause any damage. Just call your dealer though to make sure their advice is the same. If you hear it in auto as you slow down just flip the left padle to shift down yourself and it will stop the noise immediately. The software reflash will cure it for you if you can get it in to your dealer.

 

if you hear something that sounds like a metallic can bouncing around inside another larger metallic can, take it to the dealer asap.

 

Hawkeye, is this the same problem as described above which can be cured by a software flash or is this a different problem?

No it's nothing like that, it's kind of hard to describe.. it feels like the metals are rubbing against each other harshly, i have no idea where that sound is coming from, might be the transmission or brakes who knows, i took the car to the dealer the other day and of course like always i couldn't replicate the sound when driving around with one of the engineers sitting next to me because it doesn't happen very often, so they did a full check up and they said everything looks fine.

 

What you describe is the gearbox resonance problem. It is only intermittent so can prove tricky to diagnose for a tech if they fail to hear it on a road test. Ask your dealer to speak to Ferrari as it is a known issue and the software reflash fixes it.

 

Will do, many thanks.

 

Don't think it's the same problem.

good news in the end. I had a complete gearbox failure in my California and they had to swap the entire unit, which they did in a matter of days. Ferrari and the dealer were top notch in this respect. I was driving at about 55-60MPH and all of a sudden my gear indicator was flashing Neutral "N" and I was stuck on highway. All was resolved quickly and professionally.

 

FYI when you are at a stop, and the transmission is in creep mode after a few seconds it reverts to non-creep and you can hear and sometimes feel a vibration for a few seconds.
