I have recently had my motor mounts and transmission mount replaced.

Before the replacement, the car would shake quite noticeably when the engine was being started (maybe even shake 'violently'). I thought this was normal until I had my motor mounts and transmission mount replaced. Now when I start the engine the SC430 doesn't shake at all. The difference is profound.

Just a head's up. I'm not sure what the implications are of running with bad motor mounts for a long time, but I decided to get it done because my car would shake when idle and at stop lights.

Best of luck to all.

Glad to read the repair has worked out and you saved a few dollars in the process.

My car is in the shop right now for new motor mounts due to the start-up shimmying. It usually lasts until the idle calms down. They didn't say anything about the transmission mount though. Luckily it's being covered under the CPO warranty.

There is a known and documented problem with the motor mounts, not so with the one transmission mount. That's most likely the reason it was not mentioned.

if you can post the mileage, it MAY help other owners to pay attention. just a thought. and thanks for sharing this info.

I'm scared. With the kind of crap I see people posting about on their SC430s going bad at such low mileage, makes me scared about the 2007 we just bought. It only has 12K miles on it, but I was kind of figuring it would be at least if not more reliable than my SC400 which currently has 320K miles on it and has never had a major repair.

Motor mounts went bad at 40Kish miles????? Seriously????
