2003 Manumatic shifts down but not up

Just purchased a 2003 R230 that shifts fine in Drive mode. If I tap shifter to left it downshifts one gear per tap. Tapping to the right does nothing. Thoughts?

Can you shift up and down using the console shifter? Left and right in D position should shift gears. Any warning lights?

if you have some electronic skills, take the shifter out and put it in parts
clean it up well it might just be a contacts matter

shifting left (down) works perfectly. Shifting right from D does nothing.

I have some. I’ve read up some about replacing the shifter. Definitely not a simple task but maybe I can clean some of the contacts while it’s in place.
