Fix my wheelchair accessible van

Hello everybody my name is Travis I'm 30 years old and about 5 months ago I was in a tragic motorcycle accident and broke my neck and I'm paralyzed from the chest down. I purchased a wheelchair accessible van from a sketchy car dealership in Utah called what was it called Rivers Auto Solutions the transmission failed shortly after purchasing and they refused to help with repair costs. I have it at a trusted shop that is asking $4,000 to repair. I'm hoping there's enough love out there to collect enough to fix it if you can consider donating it would greatly help me to be able to maximize my Mobility I'm a very active person and I love to go on adventures please help
