Winchester Transmission & Services rebuilt the engine and fixed a lot of things that were done incorrectly on my Mercedes. They did a heck of a job and they managed to have this rebuild finished in three weeks! This was a huge job and finding the parts could not have been easy. I picked up my Mercedes yesterday and took it for a spin and it runs like a brand new car! These mechanics are very nice people and they really did a very good job! I will continue to recommend their services to anyone!
