Help! Replace kohler diverter valve

[Mike7564]

Hello. I have a Kohler Rite-Temp® 1/2 in. Pressure Balancing Valve with Stops. The diverter needs to replaced and I got the replacement part already.

Opened the trim easily. But don’t seem to be able to unscrew the silver trim off the stem (red arrow in the photo). Can’t see why it doesn’t come off. Tips?

To remove the diverter, I use a deep socket socket wrench, right?

Looks like it just unscrews. More welly needed?

As above, more welly and maybe spray inside the hole with some lube? As for removal, yes deep socket.
