2016 f57 cooper s. Experienced this for the first time about a week ago I was shifting fast from redline in 3rd to 4th and the rpms stayed the same after shifting for a second like the clutch was slipping but didn’t manager to recreate it again after so just put it down to wheelspin. Tried it again today shifting from high rpm in 3rd at full throttle into 6th and it did it again. Is this normal or is it time for a new clutch? Drives fine otherwise and I’ve only had the car for a few weeks now so can’t say what it is for sure.

While skipping gears 3rd>6th, you have to wait for the rpms to lower before releasing the clutch due to there being a very large difference in the gear size with 3rd gear and 6th gear. Think of it kind of like having to rev up on a downshift, but it is opposite when youre upshifting into a higher gear. Don't expect your car to enjoy you going from 6500rpm in 3rd, to 6th gear and dumping the clutch. That will for sure destroy your clutch and maybe a bit of your gears.

The RPM staying high, making shifting from a low geat to a higher gear difficult is called "rev hang". It is super annoying. Not sure if a tune will fix it.

Don’t think it’s Rev hang because its the rpms staying the same after I’ve already fully engaged the clutch pedal after the gearshift.

Ah okay.

Yes that’s true, I understand that. I had a much slower car before which had no problem doing a 3rd to 6th change but I’m guessing because the mini has so much more torque than my last car it’s able to fight against the clutch causing it to slip and hold the same rpm. It drives fine otherwise with no slipping if I’m simply accelerating in higher gears so it’s probably just me shifting like a twat

Do you by any chance have a "clutch stop?" this allows the clutch to not push as far past disengagement. I have one so that I don't have to push my clutch in a mile and a half to disengage it, allowing me to shift a little bit faster. If you have one, your clutch could be not disengaging completely. That could easily be causing the issue.

The tune has to specifically address that part, my tunes do (surprisingly most other tuners don't), as I've worked specifically to reduce revhang for racecar reasons.

However, it doesn't seem that the problem is revhang here.

The "standard" test for clutch slippage is to with everything up to temperature accelerate the car up to a point you can put the transmission in a gear that is as close to a 1:1 ratio as possible. This might be 4th gear with 5th and 6th being over drive.

At around 2500 RPMs floor the gas pedal. If engine RPMs rise without a corresponding increase in speed the clutch is slipping. There is no need to repeat the test. The clutch will not get better and the test if repeated can subject the flywheel to the risk of overheating which can damage it.
