Brian and Brad fixed my transmission on my 2009 Ford 150 and it is working great. They were able to get it fixed in two days and other shops told me a week. I use my truck for work so their fast response and professional service was able to get me back to work with very little business lost. Thanks again!

The customer service was great here. I had a rear main seal that broke on my toyota avalon and they replaced it for me. A week later it broke again and they found the problem to be much bigger than just the rear main seal. They fixed it all for free since it was still under their service warranty. They were very kind and understanding, I would highly recommend them to anybody.
