About Us


SD Transmissions is a family owned and operated business. We are here to provide all repairs and maintenance services for your vehicle. We keep you informed through every step of the repair process. Most of our customers have questions and concerns before they ever visit us and part of our expert quality service is providing clear and helpful answers. Our experienced technicians cannot give you a vehicle diagnosis over the phone so let’s follow up by scheduling a FREE Diagnostic. Give us a call today at 619.551.8829.
