Installed 997 shifter today..a few questions

[ScottAZ]

The install was pretty easy once I located all the torx screws holding the center console on and then figured out how to remove it around the shifter and e-brake. It's a noticeable improvement, but not as precise as I had hoped it would be. The shifts are shorter and feel better, but I still get quite a bit of play in gear, it doesn't spring back to neutral and can be tough getting into 3rd. I foolishly thought the new shift mechanism would solve this. Any suggestions for remedies? Thank you!

If it matters the shifter came out of a 21k mile 987 S.

Thanks!
