Here is some info I am copying and pasting from the Galant forums, just for the archives.
I am sure that tranny should be fine.

w5m332 means they are for turbo AWD 4g63 powered 1G, GVR4 and evo 1-3 (don't know about evo iv and beyond, anyone?).
nq -> is for the GVR4 (US and JDM)
np -> if the the US 1G and some 2G cars (up to 96; in '97 MMC switched from np to mu for the 2G)
c50ph -> is the switchable tranny (2wd/4wd)
c51ph -> if for the 88-89 JDM VR4 (early GVR4s) and select foreign market (a specimen was reported in Australia for example) GVR4s
All of the above are compatible with the GVR4 3 bolt and the 1G 4 bolt rear diffs.
wq -> is for the GVR4 RS and the evo1
evo2 and evo3 -> trannies each have letters that are different from all of the above and from one another.
The wq and evo2 and evo3 trannies DO NOT work with the US GVR4 3 bolt nor the US 1G 4 bolt rear diffs. The above data was gathered from multiple lists over a period of two years. I have found no exceptions to date.
PS -- As an FYI there are some wierd ones, for which I cannot comment about their compatibility with US cars. I'd stay away from these. They are:
nr -> unknown
f5m332sp -> unknown
w5m33?nn -> unknown
w5m33?mn -> unknown
w5m31 is a non turbo galant gsx
