Mr. Transmission Jackson rebuilt my whole transmission. They tore the whole thing down and replaced any parts that were worn or broken. This was my first time using them. I was really pleased with the work they did. I did a lot of research. I've done a lot of mechanical work in the past and was happy with the results. They were honest with me and there was a very quick turnaround. I brought my car in on Wednesday and I had it back on Friday. I would use them again.
