plamma Posted July 24, 2007 Posted July 24, 2007 <_< <_< My 460 starts off very UNsmoothly when I'm stopped at a signal light or stopped with the engine running for any reason. I was able to start smoothly when I put the transmission in the snow mode. When I notified my dealer of this condition ,he asked me to bring the auto in and he would reprogram the transmission. It seems that many other 460 owners were upset about this , and he has fixed the "problem" many times. Apparently , Lexus in its infinite wisdom has seen fit to put the transmission in neutral when the car is stopped for a period of time. I wonder how many droplets of gas this might save.

My guess is that it saved enough so that they could still qualify the mpg they targeted, or not push the car into a higher fuel use category in some states. I had the mod done and the transmission is smooth from a stop, and seems to be smoother through the gears, too. ^_^

The transmission software update is TC009-07 so just ask your service department for this transmission update.
Craig B Posted August 5, 2007 Posted August 5, 2007 I've had the transmission TSB completed on my car. The delay is gone. I would take your car in and have the new software installed. Craig
DArustik Posted August 6, 2007 Posted August 6, 2007 Some people also might be experiencing this because of the hold button function on the car. just fyi, kinda off topic sorry guys...
