If you drove it out far enough to have clearance, then it's not located correctly and will cause trouble with your trans block plate......or leak.....
At this point, it wouldn't be hard at all to remove it and replace it. If it's sticking out far enough, you can take a screwdriver and hit it on the lip to creel it up. If it's not sticking out, drill a little hole in the center and use a slide hammer to pull it out, or twist in a screw and use something to lever it out.
When you get it out, you will see that the block has a shoulder for the plug to be driven in against. That little shoulder should ever slightly be seen past rear cam bearing. Knock the new plug in facing the correct way until it bottoms out against the shoulder. It should be below the face of the block when you do it correctly.
