Hey guys so I have a automatic 2006 bmw 525i 155k miles and a couple days ago I received a transmission fault on the dashboard and I turned the car off and then turned it on and it's gone but now when I shift from 1st to 2nd gear I get a jerk noise and as well when I come to a complete stop but the other gears shift smoothly it's just from the transition from 1 to 2 gear, I also hear a little buzzing noise when the car is in a idle position , I don't want to spend a lot of money if it's something easy to fix, please help me!!!
