    I have a Dodge Caravan and my engine light came on. Took it to Mr. Transmission and they notified me that the engine had to be taken apart and the torque converter replaced. Supposedly this happens to a lot of this type of van model. I was in communication with Sean and Denise and they were able to fix my van within 2 days. I will recommend this company to anyone needing engine work. They were friendly, professional and honest.
