About a year ago, I had the radiator replaced and transmission flushed three times on my 2007 Nissan Frontier to clear out the contaminated fluid from the cracked radiator. I thought the problem was fixed but today as I was driving I lost reverse. The truck will only go forward now. I feel it is due to the faulty transmission line that runs through the radiator to cool the transmission fluid. I feel I should not be responsible for the entire repair cost. This is obviously and clearly a manufacturer problem. Nissan needs to step up and take care of their customers!
