When i start the car and the car shift from first to second gear (but only the first, first to second shift) i can feel a tap on the gas pedal i'm wondering if this is normal or anybody had experience this. (IMG:style_emoticons/default/57.gif)

go to Lexus owners club website, the forums has alot more people on it. they will answer most of your question. or you can do a search on that website also. always new question and answer from that forum each day. (IMG:style_emoticons/default/beer.gif)

You could also call a local dealership and they will be very helpful as well.
