    First, sorry for my english :oops:

    Now and then, I have problems with shifting gears.
    In accelerating, it feels like I'm in neutral, with the gear engaged.
    whether I play with the paddles on my steering wheel or with the shifter, it's the same thing.

    I've made a video, it'll be easier.:D

    Did you enable the automatic clutch in the settings?

    On a car with the sequential gearbox, the game automatically shifts to automatic clutch. I tkink?

    It's the BMW of the WTCC 2013
    But I had the problem with the Chevrolet Corvette Z06.R GT3

    Not sure about that, you should definitely enable it when using paddles.

    I don't know if it's a coincidence, but, I have this problem when I reduce the springs rate 2 steps :confused:
    and when I reset it to the original setting, it works.

    I'll do more tests this weekend.

    it was just a coincidence :(

    I just had the problem, after four laps, and it was gone after three laps.

    even when forcing the auto clutch :oops:

    I reinstalled the game, the drivers of my racing wheels, my pedals and my shifters
    I was quiet for a while.
    And here we go again

    Looks like you're just spinning the wheels and hitting the limiter?

    Just had an idea after watching both of your videos: I think it has nothing to do with a clutch malfunction since there's absolutely no signal visible on the input meters. I noticed that it always seems to happen, while you're cornering hard and at the same time trying to accelerate. So it might be possible, that your inner, and unloaded rear wheel spins, causing the engine to rev up into the limiter. An open differential (if you changed that in the car's setup) could exaggerate that issue. I'm not sure if that's adjustable at all on that 2013 BMW but might be worth a look.

    I don't think it's a clutch problem either.
    When I accelerate, it goes to the limiter, and when I release the throttle, the engine makes no more noise

    I also have the impression that I only have a problem with cars that have a sequential shifter.

    What do you mean "the engine makes no more noise" ?

    at 15s in the video, it looks like the engine is "suffocated"

    Do you run any assists? This could be some weird bug with traction control.

    Also, when you said you did reinstall of RR, did you also delete the folder in Documents? If not, maybe try setting new profile for your wheel

    Yes I've delete the folder in Documents

    And no, I play without assistance. But on these cars, the clutch automatically switches to auto

    Try recording some laps with second monitor and then I can see what's going on once and for all.

    Thanks for taking the time to record upload that. I've had a look though and here's what I see.

    Firstly, I can clearly identify where the issue occurs, as the rev trace becomes spiked as you see below.
    Interestingly, there is a big spike in throttle input before the issue occurs, which could possibly be initiating the issue. Our game engine can go a bit funky if throttle inputs momentarily hit extreme values as it starts a violent oscillation in the drivetrain. I'd suggest you investigate your throttle pedal behaviour to see if it's sending out spikes.

    In the graph below, the vertical reference line is at the same time point as above. Two observations here; longitudinal acceleration drops below 0, so car is in fact slowing down even though the revs rise.
    There is also a big difference between rear wheel speeds which you can see in the bottom graph shown below. Therefore what I believe is happening is the unloaded/inside driven wheel is spinning up which shouldn't be happening. What changes have you made to the setup?

    Another throttle and brake chart to show a few more of those throttle input spikes:

    Ok!
    I have to translate all this. ça va pas être facile :D

    for my throttle, I will look more carefully. But, I have never had this problem on other simu
    And on the videos I posted we see the gauges that look normal.

    For the car setup, I've changed the power diff and preload
    If you want test the set: https://drive.google.com/file/d/1WBqnJNPPjXB3tSr9HZbDtn_j_FASwbJ9/view?usp=sharing

    Yesterday I had a League race. I couldn't do a clean lap in qualifying. But during the race I did 45 minutes without any problems. :confused:
