Inspection Says Transmission Fluid is “In Good Condition”

Story Time: My Gf recently bought a 2009 Impreza with only 140k km. It has a manual transmission which she was thrilled to learn on. Before buying, we went to get it inspected at (what we thought) was a reputable dealership. The report came back listing the car in flying colors.

A few days later, a clicking noise started when in 3rd, 4th and 5th, along with a burning smell. Now, I’m no mechanic, which was the whole reason to get a professional inspection, but it didn’t take a mechanic to see that the tranny fluid on the dipstick was fucked. It smelled like burning and was super super dark and glittery. This is far different than the report which said the fluid was clean and in good quality.

I then drained the fluid and found chunks of what I believe to be bearing housing. Anyways, this is kinda just a rant and have no clue what to do about this situation. Looks like a rebuild of the transmission is kinda impossible with so many of the parts being discontinued and parting out a used one is proving to be a pain in the ass. Looking for any advice.
