    Drive it like you would a manual. I would pull both paddles and slip into neutral as I came to a stop.

    I think the most important part for saving clutch life that some people I've seen not do is the 1st gear roll out...feather the throttle like you would a regular manual and once it's engaged you can giver the beans and basically shift without lifting. If you just start accelerating aggressively you're burning an unnecessary amount of clutch.

    If you want to gun it out the gate then learn the launch procedure...I believe it's called "Race Start" in the manual. It basically dumps the clutch for you.

    Backing uphill is very bad unless you use the stabbing The fuel pedal method.
    Even backing up in general is harder on it..

    A problem has come up with the F1 transmission. Starting the engine the failed light in the left corner of the display comes on and stays on. The can is in neutral and will not shift gears. Checking all the identified areas that may affect this showed a lower fluid in the reservoir. Filling it to the max level did not help, but pushing the "low friction" button on the console causes the light to go out and you can change gears. Also the .hydraulic control unit light comes on at the dash. This light sometimes turns off. According to the shop manual the hydraulics interfaces to the transmission control unit. The question is how to diagnosis this problem. i have not seen this discussed previously.

    So disabling traction control allows you to shift?

    That's an odd one...perhaps speed sensor related?

    Disabling traction control does not always turn out the F1 light. Still tryng to diagnose the problem. The F1 was working fine for several months and then the F1 light came on. Now turning the battery off and try again.

    Can you explained what happened
    Were you driving
    Can you hear it shift
    Does the pump run when you turn ignition on
    More info would help when it first happened.

    be careful not too overfill filling to the max line will sometimes cause this but that will not prevent it from working it will just spill out cap

    Found the answer to my problem. The hoses to the reservoir starting leaking very slowly at first then dripping later on. When checking them, the clamps felt tight and no visible leaks. Checking the hoses a week later there were drips on the ground. Tightening the clamps further stops the leaks.

    When you said lower fluid I did not realize it was so empty that it would not shift
    Or
    I don’t understand which hoses to the reservoir you mean
    I think you mean that allows oil to get to the pump but not sure

    Hi Ralph
    That was the hoses I thought but I don’t think those are high pressure. if this cured your problem I believe you were just low on oil
    The high pressure hoses run to the actuator down on the transmission
    There is some pressure but not much to these hoses on the return side. The feed side is just gravity as far as I know
    Maybe if something is not working quite right they could see pressure however I have never seen that

    mostly glad it fixed your problem

    I'm never buying a 355F1. The software required for this thing is not accessible by mere mortal DIY and sometimes not even shops have it anymore. The guessing game is just too inaccurate. At least the 360 F1 (after a TCU firmware update) will talk to a a cheap scanner.

    At this point seepage of the rubber lines required hard tightening of the clamps. Also the pressure switch and one of the relays could be at fault. Still investigating.

    The 360 F1 computer will talk to a cheap scanner? Tell us how that works......

    After updating to the Challenge Stradale firmware, the 360F1 will fully communicate with OBD2 scanner like Launch X431 for all the F1 functions including error codes, live data, and activations of special functions. It was the only way I was able to solve the recent F1 issue on a 360CS. The Launch X431 also works with all other makes of automobiles out there.

    When I slip into neutral with a manual car I also release the clutch.

    Would an F1 car not keep the throwout depressed/clutch disengaged in neutral? I would think it would want to be ready for gear selection.

    The F1 gearbox pushes the TO bearing all the way up against the pressure plate right at the point of initial slippage even in neutral.

    Interesting. The 355 and 360 systems are nearly identical....wonder if that change can be applied ot the 355 system.
