Need new Transmission For My Truck

My name is William and I don't make that much financially in the long run. My father let's me use his truck to go places but only hold 1 person besides myself cause it's a stick shift. I have myself my fiance and 3 to sometimes 4 kids that wanna do stuff but can't. My truck needs a transmission for it which it hauls 5 people like used too..Not being able to do stuff as a family takes a strain on the happiness in the relationship. We aren't looking for much. Just to be able for all of us to do something and go somewhere together.
