Hi guys.i;m sorry if i posted in wrong section.so my story :-( . i just bought a 2003 bmw x5 3.0L with 115k miles and next morning when i started the car and put it in drive it slips :-( and put in reverse and reverse was working fine.after a minute of pressing a gas it start move and 2 minutes later it starts working fine for the rest of the day.I took it to one european car garage in they said its need to be rebuild because of internal slip.Just wondering that's sounds right?and no check engine light is on or any other warning lights is on.
