I have noticed that my SC430 does not seem to down shift appropriately. I notice it when I park the car at work. I park in an underground parking garage and I can hear the echo of the car's engine against the walls. WhiIe I am coasting, if I hit the gas a bit the engine revs but the gears don't seam to engage for a second or two. Is this normal?

 

Hmmm. Haven't felt that on mine. Assuming you're not in Snow Mode. I'd reset the ECU.

 

Thanks roofless. I'll check it.

 

not sure thats normal or not, but I do feel SC430's transmission works slower in shifting gears when compare to other cars like LS430.
