Welcome to J & M Transmission and Auto Service
J & M Transmission and Auto Service is the transmission Diagnostic Specialist in the Sioux Falls Area. We have been in business for over 25 years. We started out only doing transmission work, but as transmissions got more complex we needed to work on the entire vehicle. There are many things on vehicle that can affect how the transmission works. Our ASE Certified Master Technicians know your car or truck inside and out. We can determine if the issue is inside the transmission or not. Over 50% of the time the problem is not in the transmission at all but in one of the other systems in the car. We at J & M can repair your car whether in is the transmission or not.
If you do need a transmission we can get you on the road fast with our Certified Remanufactured transmissions. These transmissions carry a 3 year/100,000 mile nationwide warranty. We can normally have you back on the road in a couple of days.
