I have had great service at J & M Transmission in Tea, South Dakota. My first experience with J & M was in the fall of 2016 when I had some major transmission problems. The service was performed and the car was ready when they promised. I have had no recurring transmission problems. My latest experience was with the engine light coming on and they diagnosed the problem and fixed it promptly. No problems with that since. The management and technicians are friendly and seem very knowledgeable. I will continue to use J & M for any auto service and maintenance and would recommend them highly.
