I have a 2006 Jeep Wrangler Rubicon TJ and brought it to George for a transmission replacement. The TJ manual transmission 6 speed is plagued with problems and George didn't know this. His go to transmission builder is Jasper. It took three builds (in and out), which George had to put in and take out to get a tranny, which shifted like factory. I don't blame this on Jasper or Mr. Diesel at all, this is just a horribly problematic transmission Jeep put in TJ's. However George and his crew never waivered and stood by me as the customer and worked with Jasper and made everything right. George and his wrench crew is the most professional bunch of individuals I have run across in a long time. This wrench crew sets the standard for the rest of vehicle repair community. I will always recommend this bunch to repair any of my family or friends vehicle's.
