Trans Code "MX0"

[MrThick]

im listing all of my SPI codes into a journel and i came across "MXO" which is described as "TRANSMISSION, AUTOMATIC (MERCHANDISING OPTION)". Does anyone know what this means?

IIRC, MXO is a general code for an automatic transmission - you should have another transmission model-specific code to go with it, like M30 for a 4L60E.

Also do you happen to know the code "16Z"? I cant find it anywhere.

No idea - could it actually be 1SZ with a smudged S? I have 1SZ on my Tahoe, which the internet says is "DISCOUNT, OPTION PACKAGE" - "It is an internal code for “preferred equipment savings” or something like that, used across all GM vehicles that bundle features into trim level groups. It does not designate any particular option, cannot be independently ordered, and does not have a price."
