Unfortunately tee's don't fix swing path and face angle which is the cause of a slice. You can somewhat fix a slice with a draw bias driver, weighting the heal of the driver, using low spinning balls or cheating with lubricant / chap stick on the face of the driver. All those options would help reduce a slice much more effectively than a tee.
