Transmission problem
2007 BMW 328 6 cyl Two Wheel Drive Manual 60000 miles


2 days ago, on 1 st gear, the car was like loosing power. It looked like the car was chooking so I had to give more gas in order to keep it going, but on 2nd, 3rd and so on no problem. There also was a burned smell. The car is presently back to normal. This also happend 1 month ago but went back to normal after.
