    This is happening to thousands of mostly 05 and 06 pathfinders. Nissan denies the problem as it usually occurs after the 80,000 mile warranty period. If your transmission still has bright red transmission fluid get it to a garage quick and request that they add a transmission cooler and eliminate the cooling loop thru the radiator. If your transmission fluid is pink then just go ahead and have the transmission rebuilt and a cooler installed. Nissan will charge you up to 6,000 for this job so go to your local transmission shop instead. Google pathfinder problems and join the list of people ripped off by Nissan, never buy another nissan product and join the class action suit against Nissan. They installed a defective radiator in these cars and refuse to take responsibility for it.

    Had Radiator rupture and mix coolant into transmission, destroying both of course. Noticed the issue when I drove at around 50-80 mph. Experienced hard grinding like vibrations and hesitation when this happened. Drove this way for a weeks then took into a Nissan dealer. Was told they couldn't find the issue. A mechanic rode with me to see if he could experience what I did, but would check again when I rescheduled. Meanwhile during that ride along I mentioned what I suspected it to be because I did search on the internet about the symptoms. This exact same thing is what I read people were having.

    Rescheduled the appointment Tuesday of this week and within an hour and half they called to inform me what I told them it could be. Radiator ruptured and leaked into transmission destroying both. $7,600 repair but luckily it was covered 100% because I purchased the 5-yr warranty 2 years ago.
