Nissan Pathfinder Transmission Problems

    will checking the color of the trans fluid every 1 or 2 weeks or so at least let you know if you have a potential problem starting like if you see a milky strawberry color of the fluid,or will just bypassing the radiator completely with a good transmission oil cooler kit with a thermostat on it solve this underlying problem for good.?

    Nissan called me back today. Just what I expected. They will not assist in the repair of the radiator or transmission problem. I was told by the regional specialist that she is not aware of what Nissan will do in the future as this problem becomes more of a concern with customers of Nissan Pathfinders. I hope that Nissan gets nailed to the wall with this and has to pay out millions to fix all the faulty radiator in the 2005 and 2006 Pathfinders in a recall. I will be the first one in line.
  • Two years ago, I had this problem with our 05 Pathfinder. Had the radiator replaced by Nissan and NO love from them on the repair. Everything worked fine until a couple weeks ago. NOW I've learned that as a consequence of the radiator fluid in the transmission two years ago, our tranny is cooked and needs 4k worth of repairs. Bottom line, if you think you have fixed it by replacing the radiator, you probably haven't.

    I just had someone replace the radiator, drain the trans. The Trans is better but not completely 100%. I will see how it goes. The trans seems to be improving every day. I am keeping my fingers crossed.

    for what its worth I would have the transmission flushed and new fluid changed for about the next 2 weeks ,you may just have caught it on time because usually one flush and change isn't enough,the torque converter may has some contaminated fluid still in it.

    Thanks 99accent, if all goes well the next few weeks I will take it to have the system flushed to remove all the fluid including what is in the torque converter. When the trans was drained there was no visual sign of water. The fluid was just a brown color. I will let you all know how I make out in the next few weeks.

  • Our 2005 Pathfinder (87K mi) was recently diagnosed with the same issue everyone is having. The dealership wants to replace the radiator, flush everything, and then check on the trans. We'd like to have a shot at Nissan helping us out, but we can't wait on them to respond before we start the repair. The dealership is giving us two options on a radiator 1. Nissan brand, 2. other brand. Questions:

    1. If we start the repair now, which brand should we go with? (keep in mind we'd like nissan to reimburse us for the repair)
    2. Has nissan actually reimbursed anyone for a repair, or has everyone who's had nissan assistance waited on them to make the calls re: repair and pay directly?
    3. Any other advice.

    Thanks for the help!

    I wouldn't wish a pathfinder on anyone. I regret buying mine. I have 45k miles and I had a ujoint replaced (under warranty), did the radiator and flush as a precaution for $600. Just a few days ago the heat/air blower motor stopped working. I removed it and it was rusted out. Found out that the fresh air intake cover isn't seated very well so it's probably going to be a recurring problem in hard rains. Too early in the game for me to have these issues. Not to mention the gas mileage is horrible but I knew that going in. You're better off getting a V8 in the same class SUV. I've heard they get better gas mileage. Look for a 4Runner.

    For what these are "valued" at they aren't worth the money. Up to you but I would pass.
  • I went with the Koyo A2807 radiator instead of the Nissan (Calsonic). I would imagine this was a bad batch of radiators from the manufacturer and doubt any new ones have the same defect but I still don't trust them. Maybe it was 2005s manufactured late in the year and 2006 manufactured early. Maybe a particular plant.

    I did mine as a precaution so couldn't really go after nissan for the money but if I did I would probably just no accept no for an answer and bother them daily about it.

    After intensive negotiations with Nissan Corp, I wound up paying $450 for a trans and radiator on my 2005 Pathfinder. The dealer worked with me on this. One of the reasons I got the deal was that I only had 38k on the vehicle. I then brought my Pathfinder to an excellent trans shop where they reversed the trans cooler hoses.
    So far so good.

    Find out who makes the other radiator and how it's rated. make your choice on quality and have Nissan give you the same warranty, no matter which radiator you choose. Have them change your hoses. Sometimes the trans flush has to be done a number of times and it doesn't work because the transparts are too contaminated.. Hope you have an honest dealer. Good Luck.

    its very interesting to read how many people out there are having the same issues as!! I had no idea...I had an issue 2 yrs ago with my 05 nissan pathfinder, it wouldnt accelerate as it should and then the a/c and heat stopped working. I brought it in and they said it was the radiator and transmission fluids mixing and they ended up keeping the car for about a week to repair the problem. It wasnt supposed to be so long but everyday that it was supposed to be ready they called to say the problem was not yet fixed and that it was complicated. They did do it all under warranty and I did not have to pay anything at the time (this by the way is in Canada). This weekend I ran into a major problem with the car while in the USA and actually had to leave the car there at a Nissan dealership to have the repairs done because there was no way I would have made it home. The transmission and radiator all need to be replaced, due to the rad leaking and fluids mixing again and this time they damaged the transmission beyond repair! 4 days for parts to come in and 2 days labour, estimate worse case scenario is $7000 US...yep...I just got back and now will investigate whether any of this is covered, and it doesnt sound good based on the comments posted here....looks like there is definitely a huge issue here! anyone out there with same issue in canada pls post details as I need all the info I can get...thanks

    Since initial repair was under warranty, you could argue that this the same problem and should be treated the same way. I would definitely fight for this one. And if you have it done, have a reliable tranny place switch the cooler hoses to make sure it doesn't happen again.

    you stated something interesting to me [quote,have a reliable tranny place switch the cooler hoses to make sure it doesn't happen again. ]

    Could you please tell us what switching the cooler hoses will do when everything was replaced on the guys car with an updated radiator and I'm sure they blew out the transmission hoses please explain this thanks . :confuse:

    This is getting way too old .. the check engine light just won't go off ..
    for a 2005 pathfinder LE .. this is too much
    within a year .. where do I begin?
    Jan catalytic converter 1200$
    June Fuel gauge sensor 700$
    July U Joints replaced 200$
    August Raditor replaced & Transmission flush $1274.75
    present (august not over yet) .. the dealer told me I need to replace the "other" catalytic converter, I didn't know there is another catalytic converter, for 1200$
    man .. that's it for Nissan

    How old is the battery? Have your battery checked. If a battery is going bad, your "check engine" and other warnings will start to appear.
  • ktz4ktz4 Posts: 5
    oops .. forgot to mention battery was replaced 2 weeks ago (walmart) which is a bright side because it was replaced for free (with in 3 years - defected battery) .. so the sun do shine after a big storm (or least peek out a bit)
  • 99accent99accent Posts: 232
    wow its costing out as much as getting an older 2003 or 4 pathy without the radiator problem and less of every other problem you have had, you should fix it cheap as possible dump it on a respectable dealer because there isn't any ,and then go for and older model or a different model. that tranny bill will come to $5,000. ;)
  • I am reading all these post and i am getting very upset with my 2005 Nissan pathfinder! I had problems with my Pathfinder in 2009 and i brought my car to the dealership and they told me that i needed to replace my transmission and radiator cuz the fluids were mixed. I was furious because this is my first brand new car I bought and paid off in 3 yrs. I have bought plenty of used old cars and never had to change a transmission. So you can imagine how i felt when they they told me this. So we went ahead and flushed out the transmission and changed some hoses. It cost us around $900. Well yesterday i took my 3 kids to the park and my car started to shutter and having the same problem it was having last year. I know for a fact that its the transmission again. my car stalled out 4 times before i was able to make it home. Now after reading these post i'm going to have a talk to the dealership to see what they can do about replacing the transmission and radiator..
    I did read some of the post about the lawsuit. Should i call them too? if anyone has suggestions please let me know.
    Wish me luck dealing with Nissan tmrw! ( fingers cross)
  • Hi I have a 2005 Pathfinder, and I am having the same problem.I took my truck to the Nissan dealership in March. Why? because I had a trimble when coasting around 40mph.The dealership told me that my Radiator was mixing with the Transmission and they would have to rebuild it and replace my radiator at the price of 5,000.00.So I asked around and got a local mechanic to fix it for 3,300.00.However,it didn't last for long and it's back doing the same thing.And now I have another problem it wont start and they tell me it's the DMP, that is not allowing it to start.
