While preping for a cross country trip, we took our 2002 Dodge Ram2500 in for routine service. We pulled our 5th wheel over 13,000 miles in six months. I felt confident in Mike, Ed and Freddie and all they did prior to our trip. While in Illinois, I encountered a minor issue and was able to call Sonora Transmission for a consultation and was assured all would be fine during the rest our trip. Again, confident in what I was told by Mike at Sonora Transmission. I returned to California and took my truck in for routine maintenance after our long trip through the high desert, northern plains, the Rockies, gulf coast and the Midwest. Got my truck back in way better condition and now we’re on our next adventure to Southern California and Las Vegas without a worry what so ever. Driving up the grapevine after having it serviced, I noticed a tremendous change in pulling power and torque that was not there prior to serving at Sonora Transmission. I had to call Mike and thank him for the service provided. Great Job Mike, Ed and Freddie.....thanks for all you did, replacing my radiator, charging and fixing my air conditioning and being there on the phone when a consultation is needed!!!!
