Anyone else's Shift Linkage keep falling off? Any solutions?

Reading these posts makes me think,
..... if I had an ongoing problem like that
..... well, I may consider setting it correctly,
..... then drilling a hole through the entire assembly and fitting a pin or a bolt and nut through it.

1: oem was correct & lasted 60 K miles, second one (installed by dealer) only 16k.
2: now on third one, yes going to line up correctly.
3: transmission shaft is hardened steel & well-obstructed, so attempting drilling remotely safely is not likely (also the soft arm may be preventing damage to the transmission as a sacrificial part?!)
