'97 outback 2.5 trans swap

people are often not getting it to seat the very last bit and that ends up ruining the transmission.
there are threads about seating the torque converter, i'd find a good one. one has nice pictures i think. i just seated a 97 or 98 OBW torque converter a few days ago for a friend.
here's the key: if properly seated the torque converter and flex plate *will not* touch when the engine and trans are mated together. there will be a slight gap between the flex plate and torque converter. installing the flex plate bolts will then actually draw those two together.

the clicking could the front diff - did you literally swap the entire front diff? did you set the backlash on it properly? if not that probably needs to be done.
too late now but rather than swap front diffs it would have been easier to:
swap axles instead
swap the stubby shafts - they simply pull out of the trans, you can pull one out, pop one in.
run it RWD by leaving the axles out and cutting power to the Duty C solenoid, locking up the rear transfer clutches. :lol:

you're a beast for swapping the front diff!
was the axle just a different spline count? what trans could it possibly be from - maybe the clicking is because it's a toyota transmission!?
auto stub axles pull right out in 2 seconds, only retained by a circlip. the manual trans are different and do not pull out.

And you say that the transmission is slipping??
Hopefully it's not the case, but I had symptoms like those with the junkyard transmission that some guys and I put in my Forester last month. It drove great for about 36 miles....then started making loud ticking noises from the front diff area at low RPMs (in PARK, stopped at a light, low speeds, etc) that would fade as the car got up to speed (sometimes not). I checked for loose or missing torque converter bolts, but all were there and tight. The next day, the transmission started to slip...and that began to slip a LOT. When we pulled the transmission back out and tore it down, I found out that the torque converter shaft (the larger, hollow shaft around the longer, narrower one) had broken where it goes into the front pump. It was a jagged break, and the fit of the jagged edge (like a coupling) allowed the broken halves of the shaft to keep turning together. The car drove for almost 90 miles like that before I pulled the transmission back out and realized what was going on! How did it happen? Probably because of what grossgary warned about above. We had a hard time seating the torque converter--much harder than it should have been. The tranny's donor car had been in a front end collision, and all we could figure was that the impact must have damaged something to do with the front pump or torque converter shaft. The torque converter probably wasn't seated as well as we thought it was.
Again, hopefully that's not the case with yours. Check your shifter cable to be sure that it's installed correctly and is correctly adjusted. I've seen similar, though non-severe, symptoms like yours out of older Chevy transmissions when the shifter cables were slightly out of adjustment. It could be something that simple...but you're going to need to troubleshoot and try to pinpoint the source of that sound.

you dial in the front axle seal retainers to adjust backlash so it doesn't require much work. you would just pull the axles off the trans (easy - just remove the top strut mount bolts, loosen the lower and that'll be enough to pull the axle right off the trans). then you remove the one hold down bolt and turn that large retaining ring to adjust backlash.
i'm not sure if you can "guess" or adjust that way rather than actually measuring it, but maybe. you're supposed to attach a dial gauge through the front diff drain hole to measure it. a turn or so of the rings on one side or the other or both should get it where it needs to be.
i've seen comments about it before but can't recall specifics.
