2006 Nissan Xterra Transmission Coolant Leak
This past Friday I started to notice a rough shifting experience on my Xterra when I was above 50 mph. At first, it sounded/felt like I was running over a rumble strip on the road, but eventually I realized that it wasn’t the road. It seemed to be happening only when going into overdrive.
Monday I took the truck into my Nissan dealer to have it diagnosed. I took it out with a technician so he could experience it first hand. It sounded & felt like it was going to be expensive. I got the call later in the day that not only did I have to replace the transmission, but the radiator as well. It turns out that the transmission cooling system had a hose or gasket that failed and leaked coolant into the transmission. Total bill – around $3000. Yikes. I’ve never taken it off road, never towed anything, and just had the 90,000 mile service this year where the transmission was serviced.
I Googled the phenomenon and found numerous people who have experienced the same thing with various models of Nissans over a number of model years. This is sad. I was so enamored (and really still am) with my truck. But I’m going to have a difficult time buying another when the time comes since it seems Nissan is not interested in fixing what seems to be a pretty big design flaw.
