06 Wrangler X 6-speed issues

Has anyone experienced issues with the 6-speed trans on the Jeep Wrangler X? Mine hesitates going from 1st to 2nd as if waiting for the gears to line up just right. Also, the underside creeks and squeaks when shifting from 1st to 2nd to 3rd. If riding in 3rd and I let off the gas then re-apply the gas, the whole vehicle squeaks. The gear shift also makes a rattling noise when shifting in the low gears. Any thoughts??

Visit your dealership as I am guessing this is under warranty hopefully.
