so, this '88 XT6 was making noise in 2nd gear. I suspected the synchros to be shot. So, I bought a trans from a '94 impreza.

 

yesterday, I pulled the '6 trans out, carried it down to the workbench, and started tearing into it. I found 2 teeth missing on the driven 2nd gear.

 

so I lifted all the gears out and laid the impreza internals into it. ran into an issue.....the 1-2 shift fork is a mm or 2 narrower on the XT6 trans than it is on the EJ one. I was able to drop the driven shaft in there, but could not spin it by hand, it was just to tight. So I pulled it apart, and swapped the shift forks between the two transmissions:

EJ on the left, XT6 on the right.

 

the EJ shift fork was a direct fit on the XT6 shifter rod (I bet the EJ shifter rods would have worked fine).

 

EJ front diff dropped right in.

 

after many hours of cussing, I finally got the alignment pins aligned in the needle bearings:

 

then got the EJ center diff and tailhousing bolted on:

 

tonight I'm swapping the LSD that was in my wagon to 4.111 to match this trans. and seeing if I can modify the XT6 center tranny xmember section to work with the EJ mount (bolt spacing is different....).

Cool pics! I'm a bit confused, being pretty new to Subarus. Is the pic of the split trans the EJ case? It looks just like it. Is the point of this to put EJ internals in an EA pattern case so as not to have to deal with adapters and the missing torsion arm thingy (though I see one on that case so I guess XT6's had them on the trans as well?

 

Know what you mean about those needle bearing pins. When I replaced the big double roller bearing on the back of the input shaft of my EJ trans I experienced the same thing. Wished Subaru hadn't a cheaped out instead of putting another bearing up there behind the front input shaft seal. Anyway, I ended up putting a dot with a sharpie approximately 180 degrees from the pin hole to help line it up.

 

Will-

both pictures of the transmission are EJ internals in the XT6 case.

 

reason is to replace the screwed up gears that were in it. I wanted to at the very least keep FT4WD (although I prefer the VLSD AWD center), and since genuine XT6 trannies are rare, and turbo Ea82 trannies are geared poorly, my best bet was to grab an EJ AWD trans and swap the internals. The adapter plates only work to mate an EJ engine to an EA/ER transmission.....I'm going the other way.

 

not sure what torsion arm you're referring to.

 

 

 

 

Just finished swapping the LSD into the 4.111 legacy donor diff (grabbed a legacy one with bolt in bearing retainers, as the impreza had thread-in ones....and I don't have the tool to remove them without breaking them).

 

Also, had to grind the case on it. never had to swapping these into other EA82 cases....took a picture of the mod:

Nice! You shouldnt have had to grind the rear diff housing, I had the same problem when I converted my 3.9 to LSD, and if you put the bolts in the ring gear after you install the assembly, it fits with no problems. Kind of a hassle, but no mods to the case.

I've done it to Ea82 3.9s many times without grinding. no problems. this one was definitely a different casting. couldn't even get the ring gear past the little nubs (could also be that the 4.111 ring gear is a bit larger than the 3.9 one).

The adapter plates only work to mate an EJ engine to an EA/ER transmission.....I'm going the other way.

 

ah, right of course. Usually people are D/Ring their EJ not the other way around.

 

 

not sure what torsion arm you're referring to.

 

I don't know it's proper name, but I was referring to the dogbone that bolts to the chassis and to the trans on EJ's and on the engine on all EA's (I thought). Anti-roll bar? Anti-torsion bar?

pitch stopper. XTs (6- and 4-cylinders) bolt to the trans like EJs.

"new" radiator (by new, I mean old, standard EA82, but not corroded to dust like this one) is in. new clutch cable is in. 4.111 clutch-type rear LSD is in. old clutch kit is out.

 

tomorrow, it's the transmission.

 

Oh yea....speedo gear was a different size. had to swap it. but was a direct fit onto the XT6s shaft.

 

 

EDIT: pictures of the damage:

good stuff ' legos '

so chux will a EA82 D/R fit into a EJ trans case?

it would take some pretty in-depth fabricating and machining, as the EJs don't have the extra input shaft bearing (or it's bolt holes), the pivot for the shifter fork (the XT6 single-range case has this, but the EJs don't), and I suspect the case would have to be clearanced a bit.

Pretty much. The early Legacy cases DO have the boss in the case for the low-range shift lever (not drilled out, but its there), and they do have the bulge in the case for the low-gears, but you would have to modify the case for the input bearing and the shaft for the low gears, as well as drill out the boss for the shifter lever.

 

Of Course, with an aluminum forge, you could just cast new cases with all these mods already included.....

thanks guys
