I wasted no time getting the ASP pulley on my SL55. It went on today. It responded much better than my CLS 55( i dont think the intercooler circuit ever got worked out)

Anyways, At full throttle shift 1-2 it has picked up a thud like a trans mount is going. Has anyone replaced the transmission mount on their SL55? I was wondering if it was a common problem. The car has 31k mile btw.

Thanks,
Scott
