[08 335xi Advice]

Hey all, New to the forum...

 

Here's my situation: I've had my 08 335xi since Dec of 2018 and it's been amazing. Just the normal maintenance stuff. Yesterday the E-pack in the clutch went out and I need a new transmission...its $3k.

Opinions or advice on if I should replace the Trans to keep or sell, or try to sell as is? Market value on my car in good condition is between $8-10k, but if I sold I'd obviously bring the asking price down to ~$6k.
