The vehicle was experiencing problems shifting into overdrive, then once in overdrive, I was losing the capability to accelerate on the highway and other areas of speeds greater than 40 mph. I noticed transmission fluid leaking from the transmission and took it to an auto repair shop. I was informed that the transmission cooler had failed completely allowing radiator fluid to mix into the transmission fluid causing damage to the transmission. The repair for a new radiator and installation, as well as a rigorous flushing of the transmission cost $599. I am currently, as of this day, in need of a new, used, or rebuilt transmission because of damage caused by the failure of the transmission cooler within the radiator.

Driving my nissian Frontier, experienced emmission lights. Replace one catalyic converter. Just after 80, 000 the second one goes, and I have to replace it. Then the transmission stops shifting. The radiator rots and coolant contaminates the transmission, and both are shot. There are thousands of people with the same problem, and Nissan is not recalling it, and if it is over 80 thousand they do not cover it, even though it is a bad design and know to Nissan. They extended the radiator coverage, but only to 80 thousand miles. Most failures are just over that mileage.

I have a 2006 Nissan Frontier. While driving down the road the truck shudders and shakes and cannot shift into gear. I had no pick up while driving on the interstate and had cars speeding by me at 75mph while I was barely able to drive the truck. The truck would drive fine and than this would happen out of nowhere. I took it to aamco and found out I had water in the transmission due to a leak in the radiator. I had to pay $2500 to have my transmission rebuilt and a new radiator installed. I feel this should be a recall on Nissan part because it was a faulty radiator that caused the problem and could have caused a severe accident. I have heard of alot of complaints regarding this same problem but Nissan refuses to due a recall. I have the same fuel gauge problem that was just recalled and I ran out of gas because of it. I feel that this needs to be investigated before someone is killed in an accident because their transmission just stops working while driving on the interstate.
