C43 amg knocking sound on full and partial lock when driving slowly from cold

[Peterjj]

Can anyone advise ?, I get a knocking noise as if the tyre is jumping when turning the car usually more so when the car is cold on full or partial lock. Also in this cold weather the car has taken far longer than normal to change thro the gears and seems to be stuck in gear . I noticed that when I had the lights on you are able to wobble the stick whilst in drive making the light intermittent. Today the stick was in drive and all was fine !!. Any comments appreciated folks
