The slightly rough, on my 2000 corolla when everything was well you woulnd't notice the shift unless you were looking for it. With my 335i I can feel almost everytime it shifts and this is just regular driving from a stop light 1500-2200rpm 0-45 mph. I get a very small slight jerk. Also it's kind of slow, sometimes when I'm in bumper to bumper and it tries to shift from 1st to 2nd it feels like it starts shifting but holds it for along time feels like something is grinding, there are slight vibrations. Is that the torque converter ?

07 335i 35k miles JB4 (happens with MAP 0 - stock, and map 1) , did reset the transmission the other day by holding the pedal for 30 seconds and the 5 second + 2 minute wait thing but it still happens, although it did make DS mode shifts much smoother (no jerks), smoother and faster than regular drive mode.

What is the 5 second wait + 2 minute thing?
I've only seen the accelerator depression for 30 seconds after putting the car into mode 2.

Either way, that doesn't "reset the transmission" it just resets the throttle adaption...you'll need a cable, INPA, etc. to reset the transmission adaptation itself.

BT cable ? Which cable is best ?

I recently changed my fluid and pan but i do experience these symptops like OP mentions. I think i need to now reset my tranny adaptation.
