Where do I begin?I'll keep this short and simple.1. Honesty2. Integrity3. CommunicationWhen dealing w/ mechanics all 3 of those needs are never met or hardly ever met.3.5 Altima Coupe that needed Transmission work done.The owner is straight forward and a wonderful person to talk to about anything related to your cars work. W/ basic common sense you'll see what a hard working mechanic he is, a mechanic not out for money but takes your safety into consideration as well. Parts take time, as we all know if you want good work done it takes diligence. Looking for a quick fix take it to mavis or pepboys, they'll be happy to keep milking you while doing the bare minimum to keep you coming back.

Brad, the owner, did an incredible job on my truck’s transmission. The Ford dealer told me I needed to replace the transmission because of some codes that were coming up. I said why the truck still runs fine. So I took it to tri county. Brad‘s team was able to replace just a few parts and get it back up and running affordably.

It was a pleasure having Tri County Transmisson repair my car. Brad, the owner, was prompt and courteous in responding to my initial call on a Tuesday about my transmission problem. I explained that I was a Crossing Guard in town and needed whatever was wrong fixed as quickly as possible to be able to get to and from work. He took my car right away and worked overtime to diagnose the exact problem. He then kept me informed of his progress and repaired a differential and transmission leak in just 3 days. Tri County is a customer oriented, honest business and has earned my trust . I will be a faithful customer and highly recommend you consider them for your next repair.
