p400f Posted September 29, 2008 Share Posted September 29, 2008 My overdrive light started flashing. I was driving on a road that I couldnt stop on, so I turn the O/D off then back on and it keep flashing. What does that mean?? I called Lexus and they want me to bring the car in. Mind you I always get the car serviced through Lexus and it only has 267K on it. There's a second between the flashes. Anyone else have this problem? Am I in trouble? Is this a sign for bad things to come? And advice? Quote Link to comment Share on other sites More sharing options...
TA in KC Posted September 30, 2008 Share Posted September 30, 2008 Only 267K? The light generally indicates electrical problems within the transmission. Since it sounds like you usually service your car at the dealership, you should bring it in and have them check the diagnostic codes. The problem probably lies in a solenoid valve or speed sensor.

93ls400walt Posted October 2, 2008 Share Posted October 2, 2008 you need to check the Cel codes. Is your trans shifting OK? The solenoid shift sensors which shift the gears seem to be a common issue with the O/D flashing. My 93ls just started this and will not shift into overdrive. My Cel code is 42 for the #1 vehicle speed sensor. I have not changed it out yet. Quote Link to comment Share on other sites More sharing options...
Lexls Posted October 2, 2008 Share Posted October 2, 2008 A flashing O/D light doesn't mean anything other than you have tranny codes, nothing specific until you read them. It's like the check engine light, it could mean many things. Here's how to read them: http://www.lexls.com/tutorials/intro/codereading.html Quote Link to comment Share on other sites More sharing options...
