new transmission for my 1m

i had a small problem with my car transmission , the shifter was jerking in 3rd and it will engage only half the way in and when i release the clutch it will go in all , i took my car to bmw dealer and they said every thing is fine outside the transmission but maybe something inside the gear box so they are changing it under warranty and same thing for the clutch .



any one had same issue ?



bmw told me to drive slow for first 2000km for the break in period

should i drive slow or i can drive normal ?
