I would give 100 negative stars if I could and that wouldn't be enough! I encourage you to look else where. They had my vehicle for about 6 weeks before “replacing “ my transmission. It ran worse when I picked it up. My check engine light came on about 2 minutes into my drive. When I got it home I noticed a dent in my fender and hood. They used a crowbar or something to pry the hood open. I immediately called and left a message about my hood. Later on that evening, I drove it and it kept stalling. . I had to return it. I call a few days later to get an update without success. Around 3:15 pm on Friday I received a text message stating “they are in the process of tearing it apart to figure out what was happening.” Monday comes and I get a call asking if I picked up my vehicle over the weekend, well no I thought it was in the shop being torn down. My vehicle was stolen off the lot. They were “concerned” enough to file a police report. It seemed that the general Manager Todd couldn’t of cared less. I wasn’t allowed to speak to the owner. Luckily the car was recovered Tuesday night trashed and ignition broke. I had no other choice but to tow it back to Aamco with having the transmission warranty. Turns out it's not my transmission they think it’s my fuel pump. I had it moved next door and my computer is not working properly and I needed a new battery. I had my battery replaced in March. This company took my brand new battery out and replaced it with a marina battery. Yes a boat battery. Todd said those batteries are better. What a joke this place is. STAY AWAY!! I was physically ill because the stress this has caused me. I don't want anyone going through this. I am not even confident that they replaced my transmission at this point. ~Larkyn

Transmission went out - within 3 days I was back in my car. Tony did some extra work for me that was noticed during the replacement that I wouldn't have known about but would have cost me a good bit later down the road. Had a small issue with the car, took it back, and it was fixed and running great by the end of the day. As a single woman, I am so relieved to find a place I can trust. Our family has been with them for years and I wouldn't consider any other shop. Service: Transmission ~JP

Phil is a great guy, very honest and he doesn't take advantage of people. He installed some aftermarket parts on my GX470 and charged a very reasonable rate for the job. I will be returning in the future for any work needed. ~Austin
