Question about 1999 Lexus RX 300
Be glad the problem is not the tranny. This is coming from two sensors inside the motor just under the intake. The sensors are called knock sensors. When these go out your vehicle does not shift into overdrive. There is also another sensor called the mass air flow that is along the top air intake tube. the price for all three is about 260.00 I got mine for about 200. The truck is running fine now and the gas mileage even went up a little more. O'rilleys carries all three parts. 2 knock sensors and 1 mass air flow.

If this started suddenly with no other symptoms, then probably your car's computer has detected something wrong and put the car into limp mode, which means you can't go fast but you can limp home. The computer gathers data from sensors which measure everything from oxygen levels to transmission data. If it gets a bad reading from any one of them, it tries to limit damage by limiting your speed. The problem could be a bad sensor, or it could be something more serious. Take it to a mechanic who can read the error codes and go from there.
