"Super friendly, and honest family business! My dad and I have both used them, and had positive experiences both times. I will definitly go back to them frist thing when i need their services!"
"Warner Transmission is a first class business! Their work, and customer service is excellent. Work was done on time and within the budget agreed upon. We did have an issue several months later while out of state, and one call regarding the warranty, and Nick stepped up and handled everything, including having us towed to another reputable shop. I highly recommend this shop, and will definitely return."
"Amazing job, replaced transmission In my 2008 ford escape and now runs like when I 1st bought it"
"World Class Service! I took my truck to Warner's just a few days before my family was to leave for a trip. Nick took the truck in and installed new steering components as well as arranging for new tires to be put on. The truck drove incredibly well afterwards, so much so that I let my 16 year old son drive it through the mountains! If you are looking for great service and quality repair work, look no further than Warner's Transmissions and Completele Car Care."
"I visited Warner Transmission yesterday to have my Allison transmission serviced. The transmission has been wonderful and I use the truck for towing my trailer across the country. I can not afford to have problems when I am on the road and have been concerned as to who would service my Allison. After talking with Doug I was assured that he knew what he was doing and hat I would receive quality service. In addition I was able to view the service equipment that he has purchased and it was clear that not only did he know transmissions (for example the Allison has two filters not one) but was willing to purchase the equipment necessary to properly test transmissions from different manufacturers. I was very impressed with the service. My truck was ready when he said it would be and the transmission is performing wonderfully."
