Thomas,
Have the Zetec and MT75 gearbox and have the same sluggish change from 1st to 2nd, have found that after a few minutes of driving the change up is as smooth as the higher gears, so now I just take it easy for the first few changes, have assumed it's because the oil heats up? I use Triple QX EP 75w90 trans oil. Have fitted the sports shift, it's a vast improvement on the Ford lever but makes no difference to engaging 2nd from 1st.
