I don't trust shops to work on my vehicles. That's why I try to do all of my own repairs if at all possible. I do all my own oil changes, tire rotations, brake work, suspension work, and even most engine repairs. I even managed to replace my own AC compressor on my Burban even though I had ZERO experience doing AC work. I did have to get a friend with a vacuum pump and gauges to help me charge it though. Within the past year I have done my brakes (NNBS upgrade), rear shocks, fuel pump, knock sensors, rear diff gasket, and oil pan gasket. The last time I had my Suburban in a shop getting work done (other than getting tires mounted while I watched) was back in 2012 when I had my transmission rebuilt. I searched high and low before I decided on that transmission shop, and I ended up going with them because they have a stellar reputation, many positive online reviews, and one of the reviews I saw on Google was from a guy I know. I called him and asked him about his experience and he praised them to no end, and he highly recommended them as they did stellar work on his wife's Tahoe. They were not the cheapest quote I got, so I tried to get the shop to come down on the price. They held their ground and explained that "You get what you pay for" and he delivers only top notch quality. He explained that to go a few hundred dollars cheaper he would have to use the absolute cheapest crappy ass parts, and he refuses to do that because his shop only does quality work. So the shop that told me they could rebuild my transmission including all install labor for under $900, I would definitely regret it because they were DEFINITELY using low quality parts to be able to do it for that cheap. It all made perfect sense to me, plus the reviews, and the personal recommendation, that all sealed the deal. The shop owner did cut me a break by giving me a 10% discount which was $250 off.
