1G Transmission Identification

[vetexr]

I bought a 91’ Talon TSI without a tranny in it, but another tranny came with it marked “W5M312VPZK” and under it “LM0031”

I can’t find any info in this exact tranny and need to know if it works in a 1g and what i need to change, I have a auto LSD rear diff in it but need a tranny.

I have searched the internet and forums for this exact tranny but never find a “W5M31” with the ”VPZK” i believe the W5M31 are from Galant GSX but don't know bout the last

both give some information. It looks to me like it is for a non-turbo model Galant, but I am not sure.
A DSM trans man should be able to shed some light on it.
Also, the auto rear diff will not work with the manual transmission. They are different ratios so you can't mix them.
