I received a recommendation from a previous customer of Pro-Tech. I phoned Rob to discuss a speed sensor and conductor plate issue on my Grand Cherokee. Rob had me describe the issue and was able to provide an approximate estimate to repair the problem without a lot of caveats as to a worse case scenario if the problem was more than the speed sensors. I brought the jeep in and they completed the work in a morning. The charges were exactly as quoted and I was advised that my tranny is very clean and in excellent shape. I had a chance to have some good conversation with Rob and Patty and found them very down to earth and honest. I fully recommend Pro-Tech if you have a tranny problem.
