I recently purchased my dream real estate car, the '01 LS430. The car drives like a dream and has only 115K miles. My question is about the car's transmission linkage. With the car's interior close to "sound proof", I haven't noticed this clicking/ticking noise until today. While the driver's side window was down, I shifted the car into drive and heard a ticking/clicking noise with each engagement of a new gear. Is this normal for a car with this kind of mileage on it? The noise is definitely coming from inside the gearbox. Again, I just bought this car so I do not have any history to compare to. I really do LOVE driving/owning this car. Thanks in advance. Also, I bought this car "as is." Therefore, please avoid the comments about how you would take it back to where you bought it.
