Default Transmission help, '92 leg with JDM.

Looking for a replacement transmission for the Rally car.... 1992 Legacy with an EJ20G ('96 JDM WRX i think).

Been reading up a lot on what works and still a bit mystified... sounds like pre '97 there's different shift linkage in the transmissions? There's also the question of push vs. pull type clutch's. Then of course trying to figure out the JDM aspect of the whole thing...

At any rate, I need to get a new transmission after loosing third gear on stage at Mt. Hood rally. For now I'm looking for something cheap.

These guys out of Portland, OR seem to have a large selection.... would something like this work?

Appreciate any help you guys have to offer...


On a side note - Anyone in the Puget Sound / Tacoma / KenPen area looking to help out with Rally? I'd love to get a team going.

Any transmission from any subaru with an EJ engine will work. You just need the matching parts.

Use a pull clutch and flywheel with a pull clutch trans and push with push.

The shift linkage doesn't matter as long as you use the complete shifter assembly as a unit.

You have to match the trans final drive to the rear diff final drive.


The one in your link would work as long as you got a push clutch and flywheel and made sure the final drives match.

I'll add....

For the shift linkage you will need to have the adapter mounted on the transmission match also. There are two versions, one "male" and one "female".

Also keep in mind that rear differential ratio.

there was a variation on the shifter linkage, the way it was assembled at the shift post. but the entire linkage is swappable with another entire linkage for all AWD 5mt imprezas (93-07), and 90's legacys as well. for example i used a usdm wrx shift linkage on a 93 impreza chassis with a jdm 97 STi transmission, its all compatible

also you can use any EJ transmission but i would recommend another turbo transmission so you can keep the same clutch and flywheel and everything.

Not too mention annihilating the non turbo one in 5 minutes.

Dont buy the one in the link. Instead, if you want something a bit more up to the task, search around for any of these codes.
TY752VB3EA
TY752VB4CA - STI version 2 RA. Has longer 1st. Good for gravel etc
TY752VB5CA
TY752VB4AA

From the older style ones. All of these have decent ratios for rally applications, but are the older 4 bolt box. (TY752) Cheap these days.

But If it were me, id find one of these ones
TY754VB1CA
TY754VB1EA
TY754VB1BA - my favorite.

The TY754 boxes are stronger, more reinforced and known as 8 bolt boxes. They also have thicker gears, double synchros on 2 and 3 (some 4) and will suit your needs better than some random tranny from ebay. You might need to fiddle the dowels on the bottom of it to fit it buts its easy on the older style engines.

Just make sure you match up the ratios with a matching rear differential. They all use common hydraulic clutches, flywheels are interchangeable, parts are easy to find and shifters/linkages all the same. Throw in an STI short shift while your at it if you dont get one with the box. And youll be all around the chocolates after that.

Hope that helps.

James, I got a 91 legacy turbo that has an ej20g swap with an a/t trans. When the trans died, i just swapped to 5 spd. I grabbed one out of a 96 impreza. Its held up pretty good for the last few months, so i cant say they wont hold up. Also, all the other guys above me had good info...
