06 S65 "Pop" from 1st to 2nd gear?
In the morning, my 06 S65 experiences a pop, a brief pause then jolt, while going from 1st to second gear. It does not do it for any other shift, and does not do it after a short warm up, say 4 miles of stop and go traffic. This is a recent development. I have 75K miles. If you have a cup of coffee, you have to be careful or it will end up in your lap! Embarrassing if someone is in the car with me. Ideas?
