MBWorld.org Forums - 2006 C230 transmission problem

My first time posting.
just purchase a 2006 c230 sport:

It has 65k miles on it and it ran great for the past weeks days. . This morning I started it, put it R and then when I put the shifter in DRIVE, I heard couple grinds like (grrrr....grrrr). It's been cold here very cold since it started making that noise, I tried again and same thing happended. Then I put it in drive and started driving and was driving normal, shifting normal.

Has anyone had a similar issue like this? I'm worried with the weather getting colder now it might afftect the transmission and something might be wrong with it. The warranty is expired.

Any input is appreciated.

Thank you
