After reading all this reviews I decided not to wait and / or pay a lot of $$ to get this fix, so what we came up with is totally different cost effective and it works great, I know that this is a problem with the Nissan design but I bought it so now is my problem here goes, we cancel the lines that go thru the radiator and put an independent oil cooler to the side of the radiator with this little gadget you can be sure that you will never ever have this problem again and the transmission oil will be more cooler with this modification so the tranny will work better, cost to do this = 60 buck for the oil cooler, 15 buck to add transmission oil to the oil cooler and that's it well + what you
Step 1 - Have your transmission cooling lines disconnected from the radiator! There is an external auxiliary transmission cooler that does the job already. The only problem you may encounter is hard shifting in extreme cold. You can, if you want put another auxiliary cooler on the truck, but unless you're maxing the towing capacity every day you will not need it. The stock cooler is very large. Step 2 - You've basically now cured the only problem you will ever encounter, except for some little maintenancy things. Enjoy!
This is a known issue with Nissan 2005 and 2006 vehicles. (Currently the subject of a class action lawsuit.) Coolant leaking into Transmission destroys transmission, computer controlling transmission and radiator. Average cost for fix is ~$7,500 warranty extension offered by Nissan doesn't cover many drivers as the issue seems to often extend beyond the extended warranty of 8yrs / 130,000km. Some vehicles are not covered despite being within these two parameters. Nissan refuses to say why some vehicles of that year/type are excluded.
Got my pathfinder back in 05, never had any problems with the the truck. Its been to texas and back many times. Like couple years back when we got that horrible winter storm here in chicago it handle the road like nothing. The best suv out there for the heavy snow. RWD with the 4x4 option. all i got to say its that its the best and knkw that its 10 years old still runs like new.
It would have been really nice to have gotten a heads up on a defective part in the radiator that will eventually kill your transmission and your radiator. We bought our Pathfinder brand new in 2005. We have never had it serviced anywhere other than the dealership. My theory was that it would be better to have our Nissan maintained at the dealership so we wouldn't have any issues with things coming up that other mechanics may not know about, well that backfired! We never received a letter that some have stated that they received telling them about the potential destruction of their vehicles transmission and radiator do to the defective part. My Pathfinder is now sitting in our driveway while we try to figure out what to do..... This is frustrating to say the least. We have always maintained this vehicle per the dealership and the only thing we were told was it wasn't a problem or it would have been recalled!!!
