2013 640i GC Transmission Jerking

I went to a local cars & coffee this morning and I did some spirited driving on my way there.

After the meeting, I noticed the transmission shift very roughly from 1st to 2nd gear, as if I was hit from behind. It felt that the gear was stuck and then it just jump to engage the gear.
It doesn't happen all the time, but mostly when I drive from complete stop.

The car has 70.000 KM (46xxx miles) and I have not change the transmission oil.

anybody else has this problem?

update:
- Car was throwing fault code 102001 (air mass too high) and 118002 (mixture too rich)
- Car was rough idling and stall several times.
- I disconnected the MAF sensor and car was idling fine and drive fine, so I replaced the maf sensor and reset all code, now it's back to normal.

Thanks for posting the fix.

Good to know the maf lasted 8 years as well for you.
