Hi, I have a 2000 S70 GLT SE with 172k miles. It was a one owner car that was regularly serviced by a foreign car shop. I have had it about 10000 miles and it is a great car in great shape. A couple of weeks ago I noticed a small "Shudder" on the upshift from 1st to 2nd. It only does it when warm and under acceleration. If I let off before the shift it shifts fine. I flushed the tranny using 12qts of fluid through the tranny cooler line and it is still there. It is only between 1st and 2nd. All other shifts are good and the car drives great. Am I looking at a full rebuild or is there something else that can be done? It is the 4 speed tranny and 2.4l turbo motor.
Thanks.
