So I pulled out my transmission which is a
W5M33-2-NPXV 91-94 Eclipse AWD 5spd mfg 6/90-2/94 and will be installing
W5M33-2-NQBM 1992 Galant to 5/92 using the thread below.

https://www.dsmtuners.com/threads/how-to-read-transmission-serial-numbers-codes.283659/

Does anyone the know if there are big differences between the two?

I dont have caps or ASA anymore. There lots of differences. Also not sure that list is complete. 91 to 94 are not the same. Different sized hubs. Single vs double cone synchros. Gvr4 has different first gear

Do you know if first is taller for shorter on the galant?

Pretty sure the Gvr4's are a bit lighter duty if I have heard about them correctly.

that sucks. Lol

I’ll limp it until I rebuild mine

Piggybacking on this, but is there a significance between the "K" as the first letter before the "W5M" on some trans? Mine's a '97 and also has a K at the start of the code.

This is copy and pasted from an older thread:


DSM AWD (3.083)
2000rpm =14 mph
3000rpm =20 mph
4000rpm =27 mph
5000rpm =34 mph
6000rpm =41 mph
7000rpm =48 mph
8000rpm =54 mph
9000rpm =61 mph
10000rpm =68 mph

Galant VR-4 (2.846) (8.5% taller)
2000rpm =15 mph
3000rpm =22 mph
4000rpm =29 mph
5000rpm =37 mph
6000rpm =44 mph
7000rpm =51 mph
8000rpm =59 mph
9000rpm =66 mph
10000rpm =74 mph

My tranny-shep stage 3 with welded center diff
-Output shaft - I can’t turn it by hand
-Input shaft - I can turn it but it’s much harder than the galant trans

Galant trans
-I can turn both shaft by hand fairly easily.

Both are in neutral

Is this because of the welded diff or something is wrong?

Found this in an old post

Here's a little info from the tranny FSM about the marking codes that may help get you started.

I am not sure about USDM Galant transmissions but if USDM NQ Galant VR4 transmission is the same as JDM NQ, it has the same ratios as DSM. The Galant VR4 transmission with a "WQ" code is the one that has the same ratios as taller EVO1 ratios.

I'm going to say that something is wrong if you cant turn those shafts, the welded diff for example has nothing to do with turning the input shaft in neutral.

Hey Tony, ever think about the difference in the Front dif compaired to your Non-Galant rear dif ratios?? I haven't but want to make sure you don't trash something here. Just double check.

Definitely something wrong with this one.

Shit. I wasn’t thinking about that. I’ll have to look into this. Just finished the install. Need to add fluid and drive it but this concerns me.

I pray it’s the same. I’ll look into it tomorrow.

Thanks all for the input.

If you have the wrong rear ratio you will know, the car wont want to move and when it does it will screech the rear tires in gravel or anything soft.

I just copy-paste these infos here from my old computer.
I made this for myself a long time ago to organize the differences and I haven't proofread since. So there could be some typos or missed some, excuse me if I did.

Would the speedo be the same between the trans if the two had different gear ratios?

Will I notice it on pavement?

I found this.

Just looks like first gear is the only difference. This should work???

As long as the the tooth count on the the final drive ring gear is the same as what you had your ok......most likely 58t

The trans is installed so IDK. I spoke to guy that sold me the trans, and he had it in his 1g. All point to this trans being compatible. I'l put fluid in and take it for a ride after work.

You can use your 1g speedo driven gear. Some other car (maybe some limited version of galant vr4 too) and EVO 2/3 have a different tooth count on it. Between your two transmissions, I am almost sure that they both use the same speedo driven gear.

The FSM excerpt says the speedo gear ratios are slightly different. NQBM = 30/36 NPXV = 29/36. Both should have the same gear ratios, transfer & final drive though. My guess is because of different tires sizes from the factory with the different original platforms.
