I have been an auto shop owner for over 20 years and have been using Jasper Engines and Transmissions for 17 of them. If a client is planning on keeping a vehicle for at least 3 years, I always recommend Jasper for peace of mind and value. My rep always keeps a watch on my account to make sure I'm treated right. I have had warranty work honored in other states and have done warranty work for work originally done in other states. - Marc C.
