I had my automatic Roda Deaco Valve in my Duramax intermittently shut due to a voltage issue. I spent 4 hours waiting for their tech to diagnose the issue. He installed a new rev guard speed switch ($409+GST) and sent me on my way. The problem re -occurred on my way home. Went straight back and assessed the problem further with their tech and my voltmeter in the parking lot. He was stumped.

I fixed the issue at home by pulling 12v constant power from the other battery in my GM truck after a 25 min diagnostic check on aftermarket power draws. They offered to remove the new speed switch and install my old one for $128 labour then refund me the $409. Its been a week since they
reinstalled my old switch and I still have not seen my $409. I would not recommend using their service center
