Brought my car in with serious Transmisson issues. Simpson & Son diagnosed the problem and quoted me a very fair price. I decided to let them do the repairs and was very pleased with the results. Not only did they get it done when they said they would, my car hasn't run better. It's also nice to know that they gave me a 3 year , 100,000 mile warranty on their work. I will use them again if I ever have another Transmisson needing repair.
