The other day, at WOT, in S mode, my car didn't shift into 2nd very easily.

It bounced off the rev limiter & i let off the gas...then it shifted.

Anyone have this happen?

Also, i've been noticing a feeling coming from underneath the center of the car like a harsh downshift, but not from the tranny...torque converter??

I was reading on the C32 forum about Glycol contamination...was this an issue on the E55?
