Revs Jumping up when Upshifting

TheoK · 08-06-2018, 02:02 AM

Hi Everyone,

I have a manual BMW M240i and when i'm driving aggressively in mid to high rpms and I go to upshift the revs jump up anywhere from 500 to 1000 rpms. At first I thought I was leaving my foot on the gas too long but after repeating it and not having my foot on the gas it still does it.

I disabled the rev matching feature just to see what happens and its still making the revs jump up on upshift. Others with the M240i have the same issue as me as I posted in the 2 addicts forum.

I took the shop foreman for a ride and he agreed it was a weird that the car does that. There was a software update available but it did not fix it.

Anyone with a manual M2 having this happen on an upshift?

If it's a manual, I thought it was the same transmission?
Engine definitely different though...

That's what I thought too but I'm pretty sure the M2 has the same MT as the M3/4, which is different that what's in the m235/40.

Ah, I thought the same 6MT was used across all models. I know the M2 is the same as the M3/4, but I thought the 235/240 and anything else down the line was all sharing the same gearbox.
