2002 RX300 Increased RPM, No Codes
Looking for a bit of advice...
Have a 2002 RX300
I have an increase in RPM most notable at higher speeds 60mph = 3000 rpm.
Issue is not kind to my miles per gallon.
O/D works as advertised, no codes are generated, had the knock sensors replaced recently (due to codes), plugs are new, transmission appears great, no unusual noises.
Any suggestions would be most appreciated.

Are you sure O/D is working properly? I'm not too familiar with the RX gear ratios, but it really seems like you are not going into overdrive. Do you have an option to display what gear you are in? (The IS has a display for it)

Correct, it would appear you are not making it into the final drive gear.
From a stop, accelerate and count how many times it shifts. That should be a 4 speed transmssion, There should be 3 definite shifts. If there isn't, then you aren't going into overdrive, (4th gear)...
Given your complaint, the numbers show you are in 3rd gear. If you were making it into 4th gear, rpm at 60 mph, should be closer to 2000...
