I took my car to this place to figure out what was wrong with my transmission and they scanned it, it was a D5 flashing light that kept going off and they scanned it and came up with some codes on things that had already been fixed in the car. Instead doing more diagnostics on the car and trying to find out what's wrong they told me they would need to go in to transmission to find the problem. Me, because I know nothing about cars agreed, but after leaving took it somewhere else after consulting with a friend.

The place I took it to was able to figure out the problem right away without wanting to go into my transmission which would have costed thousands of dollars verses a pressure sensor change which only cost me 192. That's a huge difference in money. It's hard to find a place willing to take that time out to just try and diagnose without wanting to go the expensive route. But I'm glad I got a third opinion. The third opinion was the smarter route and saved me lots of money I didn't need to spend.

Love this place and have been raking my cars here for years. I did some comparative price checks before the first visit and I've been super satisfied with their work. The problems are fixed right the first time and they don't try to tell me I need stuff that I don't actually need. Keep up the great work!

They are honest mechanics. They do not cut corners or do questionable work. They will let you know if there is upcoming issues and either repair it or let you know about it.

I'm new to town and was looking for a mechanic. The transmission shop next door recommended Johnny's(head mechanic) shop and I'm glad they did. It's always a gamble finding a mechanic you can trust that does good work. Johnny was super friendly and communicative. He didn't push anything that my car didn't need on me and was extremely helpful. He's definitely my go to mechanic now and I live a 30 minute drive away. I'll gladly make that trip for good service and a trustworthy mechanic.
