This is my first post, and I searched for info on this before posting, but didn't find anything.

Our 2006 S40 T5 with Auto transmission has just over 1,100 miles on it. A week ago, my wife said the car made some jerky motions when starting from a stop. She described it as if the car was about to stall when cold, but then started took off suddenly with a jolt. It happened twice, but I hadn't seen it until today. I drove the car to pick up some take out food, got back in and the car completely slipped out of gear. I could see the tach reving, but the car appeared to be in neutral. I checked the position of the gear shifter, thinking I may have not engaged it properly, but it was secure. I pressed the throttle again, and it continued to rev and then abruptly slammed into gear. At this time, I was leaving a stop light and wanted to get across the street, so I continued to give it gas. It appeared to be driving OK, but less than 15 seconds later, it slipped out of gear again, and then abruptly back into gear. Once I was out of traffic, I stopped the car, moved the shifter through all the possible positions, returned it to drive and took off. All good for about 3 minutes, and then it did it again. It did it one more time before reaching home; all 4 times in less than 10 minutes.

Has anyone reported problems with the auto transmission in the S40? If so, could you please send me links to info on this. I will contact my dealer tomorrow morning, but curious to know if there are any known problems.

thanks for reading,
Dave
