It is completely possible but you may need to change out all the parts. The issue with mine necessitated these changes outs. It wasn't because all the parts were bad it was because they couldn't get the $20 connector out and had to break the entire unit can replace it. They quoted me 2400 dollars. Luckily mine was covered under warranty. The key for you is if you will be able to get the connector out. If you can then you should be able to just put the new one in and drive. Good luck
This is based upon the assumpton that it is the o-rings in the plug.
I understand it could be the shifter arm seal which I've read about several times...or something else....?
