Transmission is breaking down

Selling as a parts car. Or if you know how to take apart a transmission it could be a minor fix. As far as I know, everything is in working condition besides the transmission. It does have some damage on the drivers side door from a minor wreck. She has a few dings, scratches, and wear and tear. I am not sure the exact mileage but it’s under 140k if that matters. Just trying to get it off my hands as I’m not mechanically inclined so I have no need for a project. Willing to take offers as I’m not sure how much to sell a partially broken down vehicle for. Thanks!
