Trans seal part identification

[macdiesel]

I have been dealing with a slow leak over the years. Kinda covered the the top of the shift shaft lever. Originally, I thought maybe it was mist from the trans breather or coolant residue from one of the many coolant leaks I’ve had. Not a huge leak. Mostly fluid spray seeping out. Looks like it’s the seal under the shift arm. Tried searching SOF and the internets with no avail. I did find a seal but it was for the whole shift lever arm. Basically the seal under the one in question.

Has anyone replaced this seal? Know the part number or a like part number?

Vehicle: 2013 LTZ turbo with the first gen transmission.

Thanks

Rockauto sells the seal. National and Timkin brands. Same part number 221610. Ordered and will see if it fits.
