Hard first shift otherwise shifts very smooth
Question for everyone I did a search and was unable to find anything. My 98 WS6 with 109K on it is stock with the exception of a SLP lid. I have noticed that when I first start up the car and begin driving the first shift is hard, like it kicks pretty good but every shift after that even if from a stop is very smooth. It's seems like it does this every time I first drive the car. Any ideas what this could be? It is a 4l60E that is stock to the best of my knowledge
