Cooper GT Posted July 1, 2008 Share Posted July 1, 2008 Have a 2000 ES300 86,000 Miles. At least 3-4 times a day the car will not shift into overdrive (4th.) The fluid is clean and has been changed by the Lexus dealer when recommended. The O/D light is not on in the dash. I can turn it on via the switch on the shifter. Any ideas??

I have exactly the same problem showing up this week. I have also had problems with the antiknock sensor. I believe this is some sort of computer override which is keeping the system from shifting. There was a posting indicating that the two problems may be related. I think this is some sort of fail safe condition that is set when a problem is detected.
