Came across NAR via car-part, and out of the five dealers I emailed, NAR was the only company to respond to my query, within the hour.
Deb was very courteous, prompt, and helpful throughout the entire process of purchasing a transmission, even going the extra mile to ensure that the trans would be shipped to somewhere other than my residence.
Unfortunately, the trans I received was not in expected condition, so that is why this review was not a 5-star review; however, Deb more than made up for it by accepting the trans back as a return, no questions asked. Additionally, she even refunded me a portion of the return shipping cost. I appreciated the regular follow-up emails from Deb, even during her vacation during the Christmas holidays.
I'd do business again with NAR, but perhaps with more readily available / less 'complex' part.
