Not because of the defect as an engineer myself I understand defects happen , but because they have known about this for years and I am just finding out about it now after it is too late. I installed it in place of the cooler inside the radiator. I simply bypassed transmission cooler in the radiator. Mind you just hit the 100,000 mile mark, made last payment and ruined Xmas. Reports of this problem happen as early as 60,000 miles, but the sweet spot appears to be around 110,000 miles.
I was a loyal customer for no other reason then I hadn't had a problem, but when i did, it was big, known, avoidable, and one they could help with after the fact. I'd like to do it too. Maybe a photo would help. Transmission just went out because radiator leaked coolant into the transmission and ruined it. This process alone took 7-9 business days; I have been without my vehicle for 3 weeks. This is total loss of the vehicle since it doesn't make any sense to repair at this price a vehicle with less resale value than the cost of the repair. Would bypassing it cause problems during cold weather? I can't even believe it.
You can read their stories over at CarComplaints. The other three non-leaking transmission fluid cylinders were inspected under the microscope and five of the six transmission fluid port areas were cracked. I tow a small camper but it only weights 2k but it is up a lot of mountain roads. I went to start the car in the driveway and it wouldn't turn over. Unfortunately, I wasn't aware this was a problem and of course wasn't contacted by nissan to alert me to this! Mind you just hit the 100,000 mile mark, made last payment and ruined Xmas.
In my experience, their service work is only as good as the tech working on your vehicle. He is 85 and went to the dealer for an inspection. Nissan's negligent behavior is irresponsible at best, and borders on criminal. I looked up online and saw all of the complaints on carcomplaints… Saw there was a class action suit which I do not qualify for since the time has passed. Turns out that there is a fuse that is blowing therefore effecting the transmission and sending a signal to the car to go into limp mode. I will never purchase another Nissan made vehicle again.
The transmission finally started slipping and rumbling at about 130k 10 years so we sold it and purchased an R51 in 06. I was forced to push my vehicle a distance while vehicles proceeded to pass me at a high rate of speed. The transmission bucked and kicked back in and I was able to drive. Traveling East on a heavily traveled single lane highway with no breakdown lane. Just last week I got a humming noise from the front of the engine, yup you guessed it secondary timing chain shoes.
Leaking coolant is mixing with transmission fluid through the cooler lines to create a toxic hell stew that irreversibly damages everything around it. This makes no sense at all. . The local dealer and manufacturer were not contacted. Addresses the issue of clogging. He is 85 and went to the dealer for an inspection.
Engine temperature gauge pegs to high. I called Nissan and explained the problem. Not only does the radiator stop cooling the transmission, but the resulting slurry of coolant and transmission fluid eats valves, erodes seals and speeds up corrosion. I was neither told about the potential for the problem, or the fix available. Not only does the radiator stop cooling the transmission, but the resulting slurry of coolant and transmission fluid eats valves, erodes seals and speeds up corrosion. The vehicle requires a complete transmission rebuild, new tcm and a radiator bypass to remedy the problem. Haven't decided what to do yet.
I had it towed to the dealer and they said that the radiator cracked and fluid got into the transmission. Truck died with no warning and no help with recall. If i read your post right, you have the fluid still running through the stock cooler. I'm sure a cooler would have helped me somewhat. Nobody thinks that such a failure could pose such a danger like this!! I have a 2008 model but I bought my car in 2011.
