Hi.. I have a 2002 Lexus IS200 Auto, I am having a transmission problem. At first I thought it was caused by my ABS sensor, my ABS light on and TRC OFF flicking, which when diagnosed it was front right side. After replacing that sensor the transmission was working fine for two days but started doing its thing again. The car will just refuse to change from 1or 2 untill it redlines, if it does change to another gear it will be just for a second or so and back down. Some days it will drive smooth for two hours or so and if you going slow there is a slight jerk as if the car is changing up and down.
