Winchester Transmission & Services recently rebuilt my transmission for me. My vehicle is running fine now, but I think that it took them a little too long to do the work. I do not know, but maybe the parts were delayed coming in. I was also surprised when they told me that the radiator was clogged, and needed replacing. That was unexpected. I did get a 24,000-mile guarantee, but I think that other places offer a longer guarantee. But, so far, so good!
