Any input is appreciated

just change the trans. the clutch, axles, and driveshaft are the same. Swapping the trans is no more work than removing and reinstalling.

Indeed. Very simple swap. It wouldn't be a bad idea to install a new clutch kit while you're there, but not necessary.
If you want to know how hard it is, I have some videos on YouTube. It was my first major repair, so the videos aren't great. I also did it the hard way. I pulled the transmission out from under the car, which wasn't very smart. Much much easier if you pull the engine (I've also got videos from when I swapped my engine). If you've got an hour to kill, you can watch my series (you can find the second part in the related videos section):
MilesFox also has videos on YouTube. I used his videos to help me. If you've got another hour or two to kill, watch his videos. I recommend his over mine because he really knows what he's doing.
Oh, I have a thread on here as well. If you've still got time to kill, feel free to read through it. You can also find numerous other D/R swap threads.
Hopefully one of these three choices will help you and give you a better idea as to what's involved in a D/R swap. It was my first major task on a vehicle and I pulled it off in 5 days. Which, to me, wasn't too bad for an internet-taught 17 year old kid with no experience and limited tools. That should speak for itself on how easy this swap is.

What do you do with the 4WD button? And does it just plug in so your 4WD light still works right?

The dual range trans has a separate lever. You swap the trim cover on the console to match. The 4wd button will then be obsolete, but if oyu were lucky enough to find a full time dual range RX trans (and diff), the vacuum solenoids that operate the pushbutton 4wd will operate the diff lock.

I don't suppose somebody knows the serial codes for these transmissions (I've found the various Subaru Transmissions Serial Tables from 1990s+ but not from the 80s)?
I picked up a 2nd transmission for our RX but have been having trouble determining if I would need to do anything else (different axles, etc) in case our original D/R fails us at the track.
it is an 1987 RX. The spare transmission claims to be from an 89 GL.
I've included a couple photos. Thanks.

count the splines on the stub shafts. they should be 23 splines. The RX has 25 spline axles. You can use 23 spline turbo axle for an automatic to use the GL trans. The GL trans will have a 3.90 final gear, whereas the rx has a 3.700
some of the individual gear ratios may be different for years in the 80's. There is a chart somewhere in this forum, search the archives

Trans in picture appears to be standard 88-89 GL D/R. Part time 3.9
RX trans would have lever low on the right side of the tailsection for difflock.

I'm just about to finish swapping the d/r tranny from a 85 gl into a 92 loyale which had the push button. I thought it was almost completely bolt-on and everything went smoothly until I went to re-connect the transmission wiring and THEN saw that the plugs were different (of course I didn't notice when the transmission was out of the car ...). The new d/r tranny has one white 6 point plug and the loyale has one white 4 point plug and one black 2 point plug.
I read this thread and jj421 's thread and I watched most of MilesFox 's ea82 videos and couldn't find anything. jj421 mentioned the issue but it was never fully addressed. Is there any easy way to swap the wiring - un plug something from the firewall or from further back on the transmission and just swap the wiring in from the other car? Or will I have to cut out some plugs and splice in the proper ones? Also If this is just a backup light / telling the car whether I'm in 4wd, should I be able to skip this step for now and get the car started to work out the bumps (I did other engine work during the swap) then worry about the lights once I'm ready for the road?
Thanks yall, and special shouts out to MilesFox 's videos. USMB always saves me asstons of time and cussing.

"...or from further back on the transmission and just swap the wiring in from the other car?"
This. Follow the wires on the transmission back, and there will be like two or three separate small two-pin plugs or whatever. Unplug it there, and swap the wiring harness from the push button to the D/R tranny.
That's what I did. The 4WD Lo connector on the D/R tranny will just hang, since there's nothing to plug it into. Try and test to make sure the reverse lights work before putting everything back together. I didn't do this, but luckily I connected them correctly, haha.
I see you're in Seattle. If you'd like, I can drive to your place and help you. Give me a couple buck for gas, and I'll help you put everything back together. I can come over as soon as tomorrow. I'm replacing a fuel pump on a GMC Jimmy in the morning, but I can drive over after I'm finished with that.

I hoped it was something like that, I wish I had seen it sooner so I could have done it when everything was still out of the car... whatever...
The car's actually in Kitsap with a buddy so there would be ferries involved.... But I'm nearly done now and haven't really been hurried or stressed - just takes time and I can only look at it once a week between real work and other stuff. So it goes. But thanks though, if I can't get it running or I hit serious issues later I'll let you know!
