So the shifter is working better!!
I about gave up on it and let it sit for a week, I picked it up again and now it seems to working a little better, I was sure it was because of the broken plastic piece but it must have just needed time to sit really let the wd40 eat through the old grease. I hit it with some heavy degreaser today as a few of you mentioned and seems to be better yet!
The spray can triflow works great for soaking up the shifter too.
I'll keep working at it but they are going to come back to life! Thank you all for the suggestions!
