Hey guys,

So I have a question about my car. I have a 2013 335i 6-Spd MT, 72000 miles, that is giving me an issue. Basically what's going on is that I'm driving the car in gear, going a smooth 2000-3000 RPM's. Thing is whenever I floor it, the RPM's jump up (as if it's in neutral or as if it loses traction) and then maybe after 1 second the RPM's stabilize and I'm able to accelerate. First thing I did, was deactivate the traction control and nothing changed. New tires were purchased this summer so I know that's not the issue. One recent maintenance item that I took my car in for was the transmission fluid flush at 67,000 miles back in July. Not sure what it could be. Let me know what y'all think.

Clutch

Put it in 5th gear at a low rpm (2-2.5k) and floor it. If RPMs jump up like you are describing, clutch is slipping.
