Hi guys. I'm the new owner of a slightly used 03 M5 with a full Dinan S2 package (except wheels). Love the car, but am trying to get to the bottom of some shifting problems. The previous owner had a Rogue SSK intalled (had receipts for rest of mods but not for SSK) and wasn't sure exactly what was installed with it (WSR and bushings??) I'm trying to track down the mechanic who installed it.
The gearbox is great except for difficult shifting into second and a metallic noise/vibration during the entire shift from 2nd to 3rd that seems to increase with RPM. The shift from first to second is much tougher than any other upshift. Very notchy most of the time. The 3-2 downshift is nearly impossible to make. Seems like the slot is hard to find and resistance to going in is very strong. This stands out even more because all the rest of the up/down shifts are short, smooth and precise.
After running a search there seems to be a few other threads referring to simular issues. Unfortunatley, they didn't reflect a sollution other than returning to stock, in the threads I found.
It seems that there are a number of other SSK owners who are very happy so I'm hoping this is just an install problem that can be rectified. My dealer seems willing to take this on but uncertain of what to do other than to return to stock.
Any thoughts out there as to what the problem is???? Also any recomendation for shops/mechanics in the San Diego/ S. LA area familiar with BMW SSK install problems.
Want to get the one blemish on this awesome car cleared up.
Thanks,
Paul
new owner
