Michael’s transmission repair fund

I am doing this very reluctantly but you will hopefully understand why I am when you finish reading my story. Since July of 2019 I have been working as a Instacart shopper. I love what I do and the people I shop for. On March 6th of this year I was finishing an order and was in the process of delivery. I was less than a mile away at an intersection When I was involved in a wreck, the wreck totaled my car. After the wreck I spent seven months unable to work, or purchase a car, thankfully last month Navy Federal approved me for a loan. In the process of searching I went over to A and B Auto who is a local used car dealership. The car I found was in the price range I was looking to pay for and the dealer was willing to drop $300 off the asking price. It all sounded great, till after I purchased the car that was when the transmission started acting up, at first it was thought that the problem was transmission sensors so it seemed I could keep on driving without it doing major damage. The car started to act up more so I ask the mechanic to look at it again and he could hear the transmission was making a sound and knew what had to be done to fix it, that is why I am here. I am trying to fix the problem as quickly as I can so I can get back to work, any help would be appreciated. Thank you.
