Brian and his employees did a great job fixing my 4l60 I brought them, much cheaper than anyone around I could find. And they upgraded all the weak parts, took them less than a day (wish I could say the same for myself with pulling it and reinstalling it myself) 1 year warranty, even offered to come look at it if something wasn't right (instead of me pulling it out and bringing it back). Highly recommend this shop, and if I have any other issues with transmissions I can't fix, I know where I will be going. Thanks gents! 5/5 will recommend you to anyone I know
