W5M33 - Firstly, M=manual. Secondly, W5*33 seems to be any (F/4WD based) 4G63 or 4G91 engine gearbox.

The last 4 letters tell you all the important things:
1st Part: Final Drive Ratio
N - 4.929 (VR4)
W - 5.358 (VR4 Evo and up)
U - 5.433 (Evo 3)

2nd Part:
G -
P - Evo 2/3 Gearbox (Double syncros on 2nd, 3rd and 4th gears, 2.750 and 1.684 ratios on first and second
Q - VR4, VR4 Evo, Evo 1 gearbox
R -

3rd Part: Front LSD?
B -
F - Front LSD (RS - Mechanical LSD)
G - Non LSD (GSR)
N -
V -
W - Front LSD (GSR - Viscous LSD)
X -
Y - Non LSD (RS)

4th Part: Vehicle
D - 90+ Mirage Cyborg
E - 92+ Cxxx Lancer
F - 92+ Galant (AKO Style)
K - 88+ E3xx Galant

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.
