I know it sounds dumb. But I hope someone can help me with this.
I just got a 2005 mini cooper with automatic transmission (i used to drive a stick shift) , So i was parking back-in, i put on 'reverse' , the car doesn't go backward even i step on the gas pedal. It is 'sliding' foward inside. It feels like as if i have put in N , high rpm with no power or movement at all.
So i put on D, and put back to Reverse, now it works.
So when i did an inspection, the car shows a sign of engine oil leakage from the top on to the exhaust sth like tat. the automotive guy said it is most likely to be the engine valve. (i dont reli know wht it is )
Does anyone know what's really going on here?
Thanks a lot.
