I was told this is an older (ea81-ea82) transmission. Can anyone identify it for me:

 

 

 

 

 

 

 

 

 

Thanks.

 

Edit: added extra pics

It looks like an EA82 partime, S/R 4wd tranny. It is hard to tell though from that angle. And there is no way to tell if it is from a turbo or non turbo car. That's important becasue the axle stubs and ratio are different. If you get the wrong trans for your car your axles won't fit and the rear diff will not match.

Here is my dilemma: I had planned on putting in a full ej driveline into my ea81, but there is a guy local to me that listed 5 trannies, which he says are brand new,for sale. His lease is not being renewed so he is blowing them out. He says that he has single range and dual range trannies.

 

If I go check them out, is there any way to identify the tranny. Can I count the splines for the axles to determine if it is a n/a or turbo tranny?

23 spline stubs=non turbo, 3.9 diff ratio

25 spline stubs=turbo trans, 3.7 diff ratio.

 

Looking at those added pics, at least the 3rd one down, I think that is a fulltime 4wd box, and the vac cable controls the center diff lock(as these trans did not have Viscous centers yet). If it was a PT trans that cable would go to a lever at the top section of the rear. Clearly that cable is connected to the bottom which is where the diff lock is. That also means this trans will most likely have 25 spline axles as only Turbos and XT6's got those trans.

 

The second pic looks like a different trans, no Vaccum cable assembly and there is a cover on the clutch input shaft. That on may be different.

So if I were to pickup the ft4wd with the diff lock, I need to find a 3.70 rear diff, correct? Thanks again.

I believe that is true. Also make sure you have a set of shift solenoids and a pushbutton 4wd shifter. Or you could use some other type of double throw switch, but it seems like a pushbutton 4WD shifter would work great. But instead of engaging the 4wd it would engage the diff lock.

Gloyale, thanks for all of the information. Are the shift solenoids specific to this trans? Right now I have a d/r 4spd.

 

Also, the pushbutton 4wd shifter for the center diff lock sounds like a pretty trick solution, and help maintain a stock lock.

The push button 4WD partime and the difflock for Fulltime trans use the same shift solenoids. Mounted just behind the drivers side srtut tower under the hood. there is a single vacuum line with a check valve(one way) that feeds vaccum to both.

Awesome, thanks again.

The diameter of the input shaft should tell you something as I think the XT6/turbo transmissions used one size clutch plate and everything else used another size.

No, only 2wd non turbo used the smaller disc. All turbos, and all 4wd and XT6 used the same disc. There is a slight difference in pressure plates and flywheel surface for the XT6. But any Turbo or 4wd clutch and will work directly.

Can I get a second opinion on these... after looking at them, to me it appears the third pic down shows the vac on the top with the cable going to the rear. Correct me if I am wrong.

 

While I am at it, can anyone provide pics of what a 4spd d/r 4wd, 5spd d/r ft4wd, pushbutton 4wd, and ft4wd with diff lock looks like outside of the car?

 

I think I am going to buy one of these trannies, but I need to know what I am looking at when I go to the shop. The guy says he believes they are supposed to be for 79-87 subarus.

 

But they are brand new, and I am guessing I will be able to pick one up for $200. However, I need to make sure I know what I am grabbing, and don't pick up a tranny that isn't an improvement over my puny d/r 4spd.

 

Thanks.

It's important to note that the Vacuum actuator is mounted the same and looks almost the same on both the S/R PT4wd and the

FT w/diff lock. The difference is that on a PT trans the lever it operates is up top of the transfer case section. On the FT w/diff lock it operates a lever near the bottom.

 

If it has a rod running along the side of the transmission, attached to a small lever above the dipstick(front right of trans) then it is dual range. If it has that and the vaccum actuator then it is a FT D/R from an RX.

If it has that low range lever but no vaccuum actuator then it is a PT D/R.

Again, thank you for the great info, and for treating a noob with kindness. Hopefully I can check it out tomorrow and get my tranny!

Not to throw a stick in your spokes, but don't XT6 FTAWD trannies have 3.90 gearing? Or did I just hear that wrong sometime in my life?

Correct...

How could he find out if the tranny is 3.7 or 3.9?

Well, the bottom pic is the one with the Difflock lever. It has an XT pitch stopper bracket on it. So it's for an XT, not sure how to tell if it's XT6

cyber, did you ever go check these out? I am very curious whether they are 1.59 D/R or not, and what diff and ratio they have.

If I was an expert, I would go check them out...
