Poor quality and over priced. With no one standing behind them.
I purchased a road ripper 1000 for my dodge Dakota and it failed in less then 70,000 miles. And no one would stand behind it even a little it. The company avoided me for over a month before I filed a complaint with the BBB. That transmission cost $2600, which is roughly $1000 more then a stock transmission. Only to have it fail in less time. I will never refer anyone to purchase a certified transmission, or even have repairs. Worst customer service I have experienced.
