Sometimes it change smooth at low rpm. I have used high rpm to change gears by easing of the gas. I change out the strainer and of the fluid.
Sounds like you have problems with a part called the valve body inside the transmission or other hydraulic control problems, i suspect you will need to overhaul the transmission to cure this.

On the driver side of the transmission pan there is a fill plug. The car must be in the air and level. With the car running fluid will run out of the plug hole when it is full. This is no fun without a lift.

hello there
The problem is with the gear oil. To keep ahead of the rest BMW started what they call life time oil for their gear boxes, though that sounds great it doesn't really work in reality, they have now gone back to recommending a gear oil change every 60k miles.
In short you need to change your gear oil and soon, the oil in your gear box is no longer effective and will damage the gear box. You'll need about 5 litres for your car and costs around £15 a litre, expensive stuff!! I had the same problem with my 328i auto, the dealer was clueless and kept quoting the lifetime oil, I changed the oil and the problem has gone and it's so much smoother.
Hope this helps, please don't forget to rate me.

it is a sealed trans. you will have to bring it to BMW to have them take a look.... they dont put a dip stick on that car and many other's so you can't do anything except bring it to them to have it worked on... sorry for the bad news.... hope this helps you

check the fluid and all the wiring plugs going to the transmission.it is not uncommon for oil to drip onto a plug and cause bad readings,or vacuum lines that are cracked.

You only need to hold the left odometer reset button while turning the key to position 1 (Accessory). Keep holding the button for 5 or so seconds until any of the following shows in the display: OIL SERVICE or INSPECTION with RESET or RE. Release the button and press it again for another 5 or so seconds until RESET or RE flash. While the display flashes, press the button one more time briefly. If done correctly, END SIA should show up for a few seconds. All done.
