Review on AUTOKAY 54132 TLA A62ZB Button Shift 2017 2018 by Warren Hess

This solved the problem for me. The shifter works again. Just make sure you remove the entire handle from the wand (you'll need a screwdriver to do this). Don't just install it by inserting a new handle entirely out of the old one. My old button broke into 5 pieces in the handle and I made that mistake. I had to disassemble everything to get the new handle back so I could remove the little bits of plastic left over from the old one.
