Default "While I'm In There" '99 Forester AT Replacement Tips?

So the AT in our '99 Forester pooped the bed and I think the transmission needs to be replaced...

There's a metallic ratcheting type noise from the center section of the trans case, from the oil pan area. Not coming from the front diff/axles/wheel bearings/driveline. Only makes the noise under load, 2WD/AWD doesn't change it. ATF drained out looking ok, diff fluid will be drained today.


To speed things along I sourced another '99 Forester in the junkyard with a Subaru Genuine Reman trans that was rebuilt in 2008.

My question now is:

Since I'm going to be swapping auto transmissions, what else should I be replacing "while I'm in there?"

O-ring on the input shaft? Oil pump drive seals? I've got a new spin-on filter inbound and will be removing the exhaust manifold to allow the trans to drop. Any other suggestions?

While I had the transmission out I used to tool to see how close the first try was, and it was close. Much easier to remove the recently-installed seal, and replaced it with a new one, installed with a proper bolt-on tool.
