Nissan Pathfinder Transmission Problems

    Thank you! I'll stick with the after market. When you say the connector tube do you mean that's the point where it is potentially leaking? I wonder if once pulling the OE rad out I can inspect that.

    Our Pathfinder had both the radiator/transmission, then the u-joint issue. The "vibrations" are different. The radiator/transmission is a shudder. The u-joint is a definite vibration that gets worse very quickly. Mechanic fixed the u-joint free of charge.
    Nissan Customer Service called last week and referred our claim to the Regional Specialist. We are now waiting for the "Regional Specialist" to call to review our claim.

    Went thru whole trans/radiator mess. Got Nissan to replace both for $450 labor charge. Called my indep trans guy who reversed the cooler hoses to bypass radiator. So far so good. If you can, ask indep Ask trans person about reversing hoses. Should work if you don't have fluid contamination. Only thing they asked me to look out for is slowing acceleration over 40mph, but all good. Good luck.

    We heard back from the Nissan Regional Specialist yesterday. He refuses to discuss anything because we have joined the class action lawsuit. He wouldn't even tell us he could help us if we took our name off of the lawsuit. Very disappointing on Nissan's part. Our only hope to recover our $5,000 is for the lawsuit to go through and win or for Nissan to finally admit there is a problem and reimburse us all. Does anyone know if the lawsuit has even been filed yet?

    So you had the coolant mixture and they did replace the transmission? What was your warranty status when they replaced it?

    Well I just got back from Nissan Dealer because my pathfinder was vibrating at 40 mph, while I was excelerating. Of course I looked up what it could be before I took it there and seen stuff about the u joint and coolant leak into radiator. Well it figures I have both problems. the dealer says it is going to cost 2500.00 for the coolant leak repair and 400.00 for the u joint repair. I just bought the car from a dealer about 5 months ago. Of course it is no longer covered under any warranty. It has about 87,000 miles on it. Does any one know another way to fix this? I live in Maryland. Thanks.

    I don't know of any. Does the $2500 get the transmission replaced? I hope they aren't proposing to replace the radiator and flush the trans fluid for that amount!

    I cant wait until Nissan is exposed in this. They are the most unethical corporate business so FAR. At least Toyota stood up the plate after their exposure and attempted some kind of smoothing out.

    Anyway, Maryland guy, bring it to Pa, Selingsgrove, Pa, its the cheapest replacement Nissan I found. Youll end up replacing all of it. And I had a new U joint put on at the same time as well, about $100.
  • Just wanted to say I've followed this forum for a little bit now, I got the 40 MPH "shudder" in my '05 Pathfinder about 1200 miles ago. I took it in initially to our mechanic and he said it was the u-joints or the rear differential. I got on the web and found this forum. Thanks for all the information shared here. Nissan is really letting it customers down with this one.

    Our issue ended up being the U-joints which out mechanic replaced and everything runs fine now, BUT, I will definitely keep an eye on the radiator.

    BTW - our gas gauge went out ages ago and our mechanic said it would over $500 to replace. We passed and have just tracked mileage, glad to see we're not the only ones in that boat either.

    Sorry it took me so long to respond quesocore,

    I did not perform the "flush" on the coolant system. I simply drained the radiator and added fresh coolant. The coolant I drained looked good, no sign of tranny fluid, so I think I'm fine.

    We would like to get in on the lawsuit, could you give me the information on how to do so? Our radiator started pushing coolant into the transmission and our car would vibrate going between 50-55 mph. It costs $5000 for a new transmission, so just like you we are wanting Nissan to reimburse us.

    I had reported a complaint to about our Pathfinder issue about a month ago. I have received a questionnaire form where they are asking for further detailed information including any repair invoices,etc. I will be sending a FULL PAGE detail of what happened with our car months ago! and also I am sending the Nissan dealer repair estimates and our local mechanic invoice where he gives a full description of what he found. The more people that report their problem with the Pathfinder to NHTSA with full details including the VIN, the better!!!!!!!

    O.K.... I have the same shutter that eveyone is talking about. I have had 2 Nissan dealers and one tranny guy tell me it is the tranny. Now that I have a warranty policy Nissan said they fixed the problem. They replaced my radiator and flushed my tranny (6xs) for an additional $891 and everything is running fine. So my question is simply... Are we being riped off my mechanics or is my tranny going to fail in the near future?? Pleaase let me know if anyone has had a tranny flush after the radiator failed and the shutter is gone.

    I am so...... confused and frustrated you have no idea !!!

    your at their mercy , after all who's knows more about a tyranny other than those who work on them every day at one time I watched a kid in a junkyard take my auto tyranny apart on a old piece of plywood and I put it back in the car myself ,ran good for years.LOL

    We have an 2005 XTerra Off Road model and have hit the same problem. The estimate for repair is $6000. I hope you will include XTerras in your call for action - they have many cross over parts with the Pathfinder.

    I am equally as disgusted with Nissan. I wrote our Congressman and Senators and they received a response from Nissan simply saying the vehicle was out of warrantly and our problem.

    What goes around, etc. I'm not a lawyer, but Nissan will eventually have to pay. Legally, the warranty should not be considered since they installed defective parts.Ypu can sign on to the class-action suit at: and report to:

    Before you go and put that kind of $$ into your truck try changing the radiator and get a good transmission flush. That worked for my 2006 pathfinder. I had two dealers and a transmissions shop all tell me that I needed a $5700 transmission. I spent $900 and all is well. I am not sure if Nissan is trying to screw the consumer or is it the mechanics trying to make money. My truck was really.... bad,,, It was shuttering in the rear betweem 40-60 mph and then it started slamming in to gear. Then one day it just stoppped going into gear. Well good luck.

    If anybody could help[ me I have a question. I am about to get a rebuilt transmission. Some one said I need to also change the sensors in the transmission at the same time because of the coolant and transmission oil mix. Has anyone dealt with the sensors in the tranny. Thanks

    That resolution may not last very long. I've done and the problem reoccurred within a few months. If your coolant was like chocolate milk prior to having the fluids flushed, I'm sure that the issue will resurface as the coolant and transmission fluid are going to mix again.
