Hi guys. I don't know if I need to start a new topic, but my problem is also related with this phenomenon. However, I changed already the bearings of the oil pump and also refreshed the transmission oil with the one specified from Lexus. However, I have noticed that the car also shifts slow (2+ seconds) when it is hot outside 26+ C degrees when I want to pass a car with high speed (thus speeding suddenly). If I drive normal I don't feel a slow change of gear from stage 1 to 2. Any suggestions?
