Priced for Boxster S 6-speed with bad 2nd gear?

[Reborn996]

Hi all, I just picked up my recently acquired 2000 Boxster S after getting a replacement transmission put in along with IMS bearing retrofit and RMS. Now I have the original 6-speed trans (70k miles) sitting in my garage which had a bad 2nd gear. It would mostly grind going into 2nd but sometimes would work. What is the going rate for something like this to help recover the costs for the new one I bought? I know the transmission can be rebuilt but not sure on the core cost of something like this?
