Transplant Transmission rebuilt the transmission in my car. I've used them four times previously. I know that they're the best in the business, because they were recommended to me by a person who was in the transmission business for 20 years. That's why I started using them. I continue going to them, because I know my life may depend on the work they do. It's not the price, because they are a little more pricey. I know they stand 100 percent behind the work that they do. You don't have to worry when you leave with your car.
