    I just found out at 132000 miles that my Nissan Pathfinder has radiator fluid leaking into the transmission fluid. the dealer told me that I would need to replace the Trans. and the Radiator at the cost of $6000.00. I have a call into Nissan to see if they can assist in paying for the cost of the repair. Has anyone had any luck with Nissan picking up some of the cost?

    You can always try to see if Nissan will pay. I wrote a nice professional letter, but it still came to a NO response from them. Whatever you do, do NOT tell them you have joined the class action lawsuit. They won't even attempt to talk to you if you have. Good luck with your new transmission and radiator. Ours is doing just fine now that we have had it fixed. I just wish we had our $5,000 back.

    Thanks, I still have not had it fixed yet. I am waiting to see how Nissan responds.

    Nissan called me this morning. Guess What? They are not willing to help out with the repair bill. This has been the first Nissan that I have purchased and I can tell you it will be the Last. Nissan just likes to talk a good game but won't stand behind their product. There is obviously a defect in the design of the radiator if so many people at different mileages are having issues. I hope Nissan has to pay for this in a huge recall. They would be better taking care of the problem now with the customers who are having issue then have to pay millions in recall bills.

    Has anyone considered trying to go after Calsonic? I believe they are the ones who make the defective radiator. Doubtful they will do anything by may be worth a shot.
  • My 2005 Pathfinder had the same issue - had been shuddering for several months. Coolant leaked into the transmission via the radiator. I sent a sample to Blackstone Labs confirming this, but the contaminated transmission fluid is very obvious because it looks like a dirtier version of campbells tomato soup mixed with milk. The tests however revealed no signs of excessive wear with the transmission.

    About 2 months ago with 78,000 miles I replaced the radiator ($200 for aftermarket, WAS NOT going to get another defective Nissan radiator), $200 for 18 quarts of Matic S and $20 for new nissan coolant. Vibration cleared up immediately. It now has gone about 3,000 miles and seems none worse for the wear. I will be towing our camper with it soon, which should be a good test.

    Moral of the story is to change the radiator and flush the hell out of the transmission, then see what happens before spending $$$$ for a new transmission. I will update this in a few weeks after towing and road trip, but have my fingers crossed.

    I posted earlier on my 2003 Pathfinder but now things are just getting worse. Four weeks ago had an issue after warming up with very slow acceleration from standing start and shifting issues (staying in a low gear at higher speeds). Had a rebuilt transmission put in and still had similar issues when we got it back a week later. Found out the engine oil was low four quarts, then the car was fine for two weeks until my daughter went on a trip 200 miles away (of course). Same issues in the beginning, slow standing start and won't shift.

    Now the local Nissan dealer says transmission fluid is "burnt" and two gears are suspect. So the rebuilt transmission has 12 month warranty, but is there some other issue such as coolant that might be causing the tranny to fail? I'm concerned the transmission shop will say its not their fault the transmission failed if the cooling is no good and won't cover under the warranty. Any thoughts or advice?

    Thank you for the tip. I am in the process of doing the same thing. I am going to replace the radiator first, drain and flush out the trans and see if it improves. Let me know how you make out it in a few weeks if the trans holds up and the shuttering goes away.

    We are having the same problem with the radiator fluid leaking into the transmission fluid, ruining both the radiator and transmission (one month after powertrain warranty expired), $6000 repair bill. I reported this issue to the NHTSA and encourage everyone else to do the same.

    Just heard back from the regional specialist about my 2005 frontier with 47000 miles on it that nissan is telling me needs a new radiator/transmission for 5400$$. The regional specialist said to bad, I have since joined the class action lawsuit. As a side note both nissan mechanics admitted to me that this is a known issue and I should call nissan customer service, of course nissan did not help. Thinking I will just replace the radiator and flush the transmission and hope for the best.

    there isn't any recalls or tranny trouble with 2003 models , its the 2005 and o6 that have the problems with the radiator because nissan changed radiator vendors those years.

    Good luck with your fontier. How do you become part of the class action lawsuit?

    I found this site that shows well illustrated views on pathfinders radiator and transmission line illustration's ,it may help you see or find what and where your problems have started. plus you can order new radiators and other cooling line parts.or give you an understanding of whats going on under that hood. if you click on the part Numbers on each item it will give you more information about it.
    hope this helps for those 2005 and 2006 model years. /exhaust-cooling/214-radiator-shroud-fitting/-c-4700_4701_4724_4730.html

    To all Nissan Pathfinder and truck owners with transmission and radiator problems, just read today that VW/AUDI will pay out more than $80 million green ones to settle a pair of class action suits over leaky sunroofs and faulty drainage systems, involving over 3 million autos. It took three years of litigation.
    $70 million went for reimbursements and modifications and $10 million for the lawyers.

    The suit alleged design defects. For years VW/AUDI blamed customers for not maintaining their cars right. Sounds familiar.

    Nissan will get there's. It's just a question of when.

    did this happen to older pathfinders ,hearsay some did, I was with a fellow pathfinder owner at the beach today, he has a beautiful well cared for 96 SE wheel drive. he was told from a few older pathfinder owners that he met in in his travels that they had transmission and radiator problems back then in 1993 and 1996 , so he had an oil cooler installed and bypassed the radiator could this be true I hope not for my 2003 SE [have has anyone heard of this with the older pathfinders? :confuse:

    WOW, I am so glad i've found this forum and appreciate all the input from all of you Pathfinder owners. I had an issue this week with my '05 pathfinder where i believe the fuel pump went out, it started and shut down then wouldn't restart and after a numerous attempts had it taken towed to my mechanic. However he replaced it friday and is still having the problem starting up. The mechanic can start it with starting fluid for a short time but it seems the pump must not be functioning to supply the system. was thinking electrical but I've checked the fuses and they are all good. Have any of you had this problem?
    As many of you have stated about the shuddering and vibration it has become noticeable within the past few months at 40-50 mph as well. I guess i am going to be proactive and get the radiator replaced and tranny flushed and check the u-joints. I sure hope this will avert what seems many of you have had to deal with which is bull@**%. Nissan, as someone else said, needs to step up and deal with the problem they know is an obvious manufacturer defect, and almost seemingly negligence now at this point! I love my pathfinder but i surely don't want to be paying for it again in major repair bills and judging by the way Nissan handling this i won't own another! I will post back what i find as well and may be joining the class action suit with you all!

    I am curious to know what peoples' view are on (1) whether or not a new radiator will avoid the coolant/transmission problem posted here and (2) whether, where a new transmission and radiator have already been installed, the car is "fixed" with respect to these known transmission problems? In other words, would one be crazy to buy a 2005 Pathfinder with a new transmission and radiator replaced at about 55K miles? It is now at 65K with no apparent problems. Thank you.
