BMW E66變速箱? 剛發動D檔打進去他會馬上跳回P檔，我在馬上打R檔先退後一下在打D檔他就好了但是儀表板有現試一個池輪的燈，有時黃色有時紅色，請問一下我要如何才能處理好謝謝?

You will need to have your BMW inspected by a repair shop, preferably an authorized BMW repairer.

1. The gear light stands for "Check Engine", meaning you need to get it inspected.

2. In term of the transmission, there are too many variable. At the minimum, it can be the transmission switch wheel issue. It may be a sensor, or even the actual transmission issue.
