My 2005 Kia Sorento, which is no longer under factory warranty, lost a tranfer case due to a leaking seal that was not observed during routine oil changes at the local quick lube shop. Saving a few bucks on oil ended up costing me thousands of dollars in the long run. Fortunately, Avon Transmission came to my rescue and after exhausting their resources trying to locate a good used replacement, they took the time to tear the original down and diagnose every gear, bearing, chain, along with a hundred other pieces to see if it could be rebuilt. They kept me informed every step of the way and made every effort to provide the most economical solution to getting me back on the road. My Kia runs like it just came off the showroom floor and I can't thank Rich and his highly skilled technical staff enough for the job well done. Avon Transmission is on the top of my list for customer servcie along with their honest and ethical business practice.
