    Hi guys,

    Couple of days ago my gearbox and clutch starting acting erratically all of the sudden. The shifts took longer with clutch slippage and when i came to a stop and was about to drive off there was a warning beep everytime i touched the throttle. If i still tried to drive off there was bad clutch slippage but it drove off. All this happened within 10 minutes maybe and was gone thereafter.

    I didn´t do any remarkable tough driving before where the clutch could have overheated. I didn´t smell anything or see any smoke or so. There is no stored error codes and clutch is worn 60% according to the computer.

    Car i at a Ferrari specialist right now for a check up and they are puzzled.

    PLEASE let me know what you find out. My 360 is doing this too.

    Don't always believe the clutch reading as the number can be reset with a worn clutch. If the clutch is slipping the clutch is either worn, or you may have a leak in the throw out bearing slave. Either way, you can't fix the problem until you dig into the area.

    Could also be the f1pump not keeping enough pressure in the system.

    Clutch reading was around 62% worn according to the dealer when I bought the car last week. The dealer did another read out on Tuesday this week and it was 59% left. I then took the car to a specialist where I found out that the real clutch wear is 89,8%. Go figure...

    It is easily manipulated. I never pay any attention to calculated clutch (or CCB) wear. IMO the only way to check is via the access panel underneath the gearbox.

    Clutch wear reading is very inaccurate. It can jump quite a bit from one dealer to another.

    Most likely your issue is worn out clutch. The clutch on my 360 Spider started popping out of gear at 78% wear reading.
    Removed and replaced clutch and all is good again. Except my pocket was $8,200.00 lighter, and that was after 10% Ferrari Car Club discount.

    Hope that helps.

    My issues were solved with a new clutch.

    I had to get a new clutch even though my reading was at 70%. Clutch is great now.

    I have a post here about my experience with clutch wear and clutch reading.

    Summary:
    Your clutch will start having issues at about 70% wear.

    Signs of clutch wear:
    • Clutch popping out of gear uncommanded.
    • Clutch starting to slip.
    There is no other fix Im aware of for the above anomalies except clutch replacement.

    F1 Clutch replacement average costs depending on what other parts needs to be replaced while the transmission is out:
    • Independent mechanic: $6K
    • Dealer: $9K - $11K.

    From my experience if you ask five indys and five dealers about the clutch reading you will get 10 different answers.

    To my knowledge, the only value that you can fake that will affect clutch % wear calculation in a "positive" way is the "Clutch Position From New".
    You can't fake the "Clutch Position Closed" value, which is the one that can give you a good hint of the current clutch wear.

    I'm curios what peoples Clutch Position Closed values was reading at the time when the clutch needed replacement?
    Guess somewhere between 20 and 25 mm.
