Installed CV axle seal (into transmission) approximately 1mm too deep. A problem?

On a Kia forte 2018, automatic.

Seal is supposed to be flush not with the outside of the case, but with the chamfered edge just beyond that. I went about 1mm beyond the chamfered edge.

ATP transmission assembly lube was used generously on the inside and outside diameter of the seal.

This is the passenger side. On the driver side, I can specifically see where the seal should be flush (the driver side is stock, never changed). I went just beyond that. Just a tiny bit too far.

Should I pull the seal and go again? I already have new seals on order in case because I realized too late that you can tap it in deeper, but you cannot pull it back without damaging the seal (first time doing this job).

If useful, this is an A6GF2 transmission, part of the Kia/Hyundai A6 transmission series (6 speed automatics).

Not sure how much that 1mm will make a difference, but I want to do the job right. I will definitely tap slower on the next install and watch carefully.

Lesson learned with these seals: You can always add more depth and tap it in deeper, but you can't take away and pull it back out.

Should I pull it and try again with a new seal?

I think it will be OK. I would worry more if it didn't go in far enough.

That seal don't have a shoulder? Should be fine either way.
