Faulty radiator causes coolant to leak into transmission fluid.
Transmission has been slipping. Happens frequently when stopped at a red light, stop sign. . . When time to go car does not move. Complained to Nissan dealer in 2014 and they suggested changing the fluid. . . Could not find any problems. Fluid was changed and I am still having problems. Will be taking it to another dealer this week. I understand Nissan has had major issues with coolant leaking into transmission as I had a 2005 Nissan Frontier and this is what happened to me. Nissan would not compensate me as my mileage was 100+k. When I treaded in my 2005 for a 2010 I was assured that Nissan had fixed the defect. Here we go again. . . I should have known better!.
