AAMCO of Charlotte replaced a sensor in the transmission of my 2006 Jeep Commander, and it works now. Because I had transmission problems, it went into limp mode and into one gear. I had my company tow it there and I called them, and then left the keys in their drop box overnight. They then talked to me about what they thought. I had thought it was one of two issues and they confirmed it. They were very clear on their thoughts and expectations, and took care of everything in a day or so. Their work met my expectations, and the prices probably were where I thought they would be. It was kind of expensive--about $850 for parts and labor--but I was expecting that.
