'Reluctant' 6MT? Well...

It may be that your clutch is dragging.

Mine isn't, as it was just changed under warrantee at the first service.

Shift action is much, much nicer.

If it doesn't want to go into 1st or 2nd going - up or down - regardless of whether you're moving or stationary and the number of time you've double declutched or attempted to manually rev-match, BUT drops straight in if you hold it against the resistance and then switch the engine off - your clutch is probably dragging (AKA not fully disengaging).

Obviously if you've fitted a clutch stop that prevents you from fully depressing the pedal this can present the same symptoms.

So for other curious members here, what did your dealer replace in your car? The clutch plate? Flywheel? The tranny? Clutch pedal? Clutch hydraulic system (shared with brake hydraulics)?

Noting that it doesn't appear to be possible to buy the friction and pressure plate separately, they would both have been replaced. The rest was inspected to make sure that it either wasn't contributing to the observed effects, or been damaged.

But, I'm guessing.

The phone call from the dealer was basically "we've completed the service but the clutch is dragging and will need to be replaced" (I had mentioned the 1st-2nd change as being reluctant on check in). They then went on to reassure me that it was covered by the warrantee, they had already ordered the parts for delivery the following day, so would pull the gearbox 1st thing and inspect it . If everything else was okay I could have the car back before the end of the day.

As it turned out, they were done by lunch.

How difficult was it to push into gear? For me im only feeling a slight resistance shifting from 1-2 but only when im moving.

I have not driven a 6MT F8x sadly, but a slight resistance seems to be normal for M cars. You should definitely not get any when stopped (except the occasional 1st gear lockout).

I see, yeah it ruins the shift experience though. It's never happened based on temperatures for me though, and I don't have a first gear lock out either, or any lockouts when I'm stopped.

Thanks for your feedback it's greatly appreciated.


Oh I forgot to mention the reason why this terrifies me is because my Evo x locked me out of 1, 2 and 3 when cold and even when it was warm. The only solution was a redline fluid cocktail.
