Hello, I'm a Lexus guy and have owned quite a few. My wife is currently driving a 2004 RX 330 that Just rolled 140k. I bought it with 127k. Since we have had it, it has has a really annoying vibration shifting at approx 20mph. Other lags, and sloppy shifts happen to at other shift points. I read others have the same issue. What can I do? Am I just going to have to buy a new transmission? I run 93 Octane gas, recently changed the fluid filter, and even added Lucas, still doing the same thing. Any help would be aprreciated.
thanks!
