I live in Florida and I used my Suburban to pull a heavy trailer to Vegas. The transmission overheated and became ruined as I pulled the hills into Phoenix. I took it here and dealt with a gentleman named Russ. He fixed it and my total bill was much less than his original estimate.
Also prior to him fixing it, my Suburban had an annoying vibration that nobody seemed to be able to fix. I had another Suburban before buying this one and it also had an annoying vibration. So after Russ fixed it now there is no more annoying vibration - and that isn't even what I brought it in for.
Also, whatever he did improved the fuel mileage. I used to be able to go about 4 hours on the interstate, without pulling a trailer, on a tank of fuel. Now I can go 6-1/2 hours on a full tank.
Also, the transmission he fixed works good I drove to Vegas and then back to Florida w no problems.
