Does it only do it when driving. Lube your shifter cables. Many of us celi owners have had squeeky kinkages. Get a friend to sit in the car and move the shifter while you spray some WD40 on the linkages. Should clear it up. As for reverse, make sure you are at a complete stop and you have the clutch all the way in. Reverse is always a little difficult to put in, have some patience and be gentle with your car.
