Hi,

I'm I just purchased a SC430 2002, I was wondering does anybody car make a clicking noise when shifting gears. Example when I turn my car on and shift from Park to Reverse I hear a clicking noise and then when I go from Reverse to Drive it makes a clicking noise. Sometimes it just goes away. Please let me know if it's a transmission issue or if this is a common sound.

I have an '04 and I hear a clunk when changing from park to reverse - just a single clunk. I have had the car almost 4 years and everything is fine so I am thinking it is normal. I haven't heard a continuous clicking ...

It could be listed in likelihood of probability :
1. the diff bearings showing slight wear.
2. The brake pads sliding in their carriers as you change the direction of motion.
Or a distant third: It could be a Universal joint or propshaft carrier bearing. This would have other symptoms too.

If it gets much less when the car is warm, then the noise is quite normal. Upon first start of the day the RPM's are a little higher and this places a bit more pressure on the transmission etc when shifting. All this is normal and is part of the normal feel and noise of operating this car.

This is likely to be the "brake clunk", as referenced in a few threads on the forum. (Do a search for brake clunk, IIRC.) The pads stick and then break loose with suspension movement. You are likely to occasionally hear it when you simply get into the car and first sit down. There are a couple of methods to resolve it mentioned in the past. One used a copper grease for the pads/springs to move in. Another put rubber pads under the springs to increase tension, IIRC.
