Not so sure it should do it quite so dramatically when slowing down, unless you are actually making it downshift with the shifter. Worst case would be that your transmission belt is slipping. You should get a Mini mechanic to try to duplicate this. He'll be able to tell you if it's normal or not. It all depends on which mode you are using and if you are doing the shifting yourself or not.
I am driving in D mode only. Car speed up ok.. its just roaring sound that it makes when speeding up.

What do you mean by downshift with the shifter.

Thanks for your help !

It sounds like you are not shifting your transmission manually. You're just leaving it in "D". If you have the feature, you can manually shift it by pushing the stick to the right and then going through the gears up and down or you can use the paddle shifters on the steering wheel.
If you're just driving in "D", your slowing down seems a bit odd. Have someone check it out.

try this speed up till 15 mph and then shift the gearbox in manual speed stays the same your rpm go shift back one time if the noice go up with the rpm your main bearing is damaged. it can be fixed under the car check your local dealer.

Good guesses here, I had a somewhat similar problem, it was a transmission belt slipping case.

powdajohn,

How did you resolve this problem? I don't know who can do this work for me, do I have to go to BMW dealer to get it done?

I was reading on other forum that I have to take my mini to the bmw dealer to get the adaptations reset for the transmission. Google (Auto gear shift in high revs - North American Motoring)

Any help would be highly appreciated especially if you've had the same issue and solved it somehow. Thanks

But when I remove foot from accelerator for car to slow down the rpm starts rising again upto 4-5 and then slowly starts to come down when the car slows to 30-40 miles.. during all this the negine makes roaring noise as well.

Just wondering if any of you have ever come across any such problem or know the reason.
Hi partner: I NEED HELP. I have exactly the same problem with my 2003 Cooper. The rpms go up to 3500 when the car slows down for stopping at a traffic light. Then after a few seconds they go down to 1000. The same will happen when I resume driving it will go to 1st gear, stay there for five to ten seconds before shifting to 2nd or third. The rest of the drive is fine, and ghe whole things happens again at the next traffic light. Whaaat a nuisance !!!

I wonder if you ever found out what was wrong ???

I took the car to a mechanic who does BMW work and he scanned the transmission and told me that everything is fine with the gear box and that the discs are slipping because of the fluid they put in it was the wrong type.
