12 years? How many runs? Lot of trash in the pan? Fluid stink/discolored? What does the rear support look like where it supports the output shaft? Pump OK? What kind of oil?
Look like it has some runs on it. If the rest of it looks OK, I would clean it up, replace the stuff that is questionable, check and fix clearances and end plays - including the pump - and put it back together.

If the results don't match the theory, change the theory.

Possible broken pump drive lug.Trans may still function but with reduced oil pressure.

like they got hot from lack of lube. Most likely.

A few years ago I had a problem that looked similar to yours but not quite as bad. During the 2018 season I noticed my 2-3 shift was spongy feeling. I continued to race like this for a few more events before removing the trans and inspecting it. Upon removal the converter did not slide out easily but I had to tug on it a bit to free it. The internals, bushings, thrusts, high clutches were discolored such as yours but not as bad. The pump had one drive lug broken off on the small rotor and while inspecting the housing, the broken piece fell out of one of the passages. I cleaned and reassembled the pump using A&A heavy duty rotors, Cleaned the thrusts and bushings, installed new high clutches and steels. Ran it thru the whole 2019 season trouble free and shifting hard and strong. Removed and inspected it during the winter and everything looks perfect. I can only relay my own experience with the broken pump lug. Can't really say why the pressure was lower but I do believe the broken drive lug caused it.
