TransmissionKnowledge.com is an independent online resource dedicated to providing practical, fact-checked information about automatic transmission problems, symptoms, and diagnostics. Our mission is to help everyday drivers, DIYers, and enthusiasts understand how transmissions work — and what to do when they don’t.
This site is run and edited by Joshua Freeman, a former transmission technician with over 15 years of hands-on experience in diagnosing, rebuilding, and explaining drivetrain issues in plain, understandable language.
After working in several independent shops and specializing in automatic and CVT systems, Joshua launched this platform to counter misinformation online and provide a single, trustworthy place for people to learn about common transmission failures, repair options, and maintenance strategies.
Our articles focus on accuracy, not hype. We don’t sell parts or services, and we are not affiliated with any dealership, automaker, or transmission brand. That allows us to remain neutral and transparent in our guidance.
