I have owned 1999 RX300 for several years now and have noticed if start up and begin driving immediately the transmission does not easily shift until AFTER THE ENGINE WARMS UP. I began the practice of letting the temp come up to the "C" on the engine temp gage. This gives not only the engine time to warm up but the fluid in the transmission a chance to warm up as well. I have had absolutely no trouble with the transmission and it shifts very smoothly once the transmission has had a CHANCE TO WARM UP.
