#425 of 1242 2006 Nissan pathfinder transmission concern
Jul 05, 2010 (7:12 pm)
I have a 2006 Nissan Pathfinder with 70,000 miles. No problems with transmission yet , but am very concerned with the problems others are having with their Pathfinder. i checked the transmission fluid and as well as the radiator fluid, and the fluids look normal. I read a post where nissan installed a badge batch of radiators causing the problems. Anyway to to tell by serial number or anything to tell if i have a bad one? Plan on checking the fluids monthly for discoloration. Should i sell it or hope for the best. Any suggestions would be greatly appreciated.

I haven't heard of any serial number or start date for the installation of the bad radiators ,you would have to see when they changed the manufacturer of the radiator,it must be documented by Nissan somewhere as to when the cut off date was for installing the vendor of the bad radiators .

If you plan on keeping your Pathfinder, I would at minumum install a tranny cooler and bypass original factory radiator or install an aftermarket radiator and replace the original factory radiator. I would be very hard pressed to trust any Nissan info since they can't be honest about this problem and perform a recall. This $500 or less fix is a great deal better than the $3,000 I have invested in mine to have the radiator and tranny repaired. $5,000 to $7,000 if Nissan Dealer was to install a new tranny and radiator. I would do this before any warranty you may have expires. We have an '06 with 127,000 on it and this problem occured. Nissan was of no help and told me I was SOL due to out of warranty. We like the vehicle but are extremely dissappointed with Nissan.

thanks for your reply. I am going to do the bypass in the am. I found on another forum complete detailed instructions on how to do this. i just wish others would have known about this problem and could have done the bypass thing and saved themselves alot of money and heartache. Hopefully Nissan will man up soon.

My original radiator was made by Calsonic. Our Pathfinder is now 76K and I decided to replace it with an after market. It will be paid of this month and we plan to keep it for a few more years. Just wondering for those who had the misfortune of having this problem if they noted the brand of the radiator... I kept mine just in case Nissan decides to replace them. I know Calsonic is a reputable brand that is why im asking if those who broke down have the same radiator brand.... cost of replacement is $300, radiator and labor, just in case anyone asks....

Sell it! Don't gamble on this!
#432 of 1242 2006 Pathfinder 45k similar symptoms

I'm glad I found this thread. I actually first read about this issue a week ago in Popular Mechanics. They published a letter by someone how has gone through this very same thing! Great to see exposure as a major publication! Hopefully that will help force Nissan to take responsibility.
I have a 2006 Pathfinder with 45k miles which I recently purchased used from a dealership. If the trans fluid turns out to be soured I'm going to ask them how this passed their ten million point inspection that is such a huge selling point.
I've recently experienced some symptoms similar to others on this thread. It started with a vibration around 75-80mph. Within the past few weeks I started feeling the vibration around 60 and now anything over 40. At the same time I started to hear a slight clicking when I would come to a stop (similar to a CV joint going bad). This clicking has become louder and I now hear it at any very low speed (< 10mph). I suspected a U joint on the front drive shaft (thatís where the noise seems to be coming from) so I crawled under to check. I'm in no way a mechanic but I was able to grab the two parts of the shaft around one of the ujoints and twist back and forth. I got a tiny bit of movement with the same clicking noise that I've been hearing. I have an appointment with my mechanic today to confirm what I found to be a problem. It doesnít at all seem normal to me. After doing some online research I've found that the vibrations at higher speeds could also be caused by a bad ujoint. I was wondering if anyone could confirm that they've had similar symptoms in this thread but found it was a ujoint issue. I also checked my coolant and it looked very clean. I'm having my mechanic check the trans fluid today also. As a precaution, no matter what outcome is with the fluid checks, I'm having the radiator replaced and the trans fluid flushed (not just drained and filled!). I ordered a Koyo A2807 rad for $210 and figure with labor and the way overpriced Nissan fluid I should be around $500. It's been suggested that bypassing the rad and installing an external cooler is a solution but I read that this may actually cause a problems in cold climates? Can anyone confirm or deny that? I'm still under power train warranty for another year / 15k miles but I'm picturing the worst case scenario here where the tranny lasts until after that. I don't really want to spend this money now but it will hopefully give me some peace of mind. When I first purchased this car 7 months ago I felt like I finally had a rock solid vehicle (especially with the winter we had here in PA) and now I feel like it's going to bomb out on me at any moment. I'll post a follow-up once I find out about my ujoints / fluid and any other diagnosis.

I have a 2005 Pathfinder with 115K miles on it and had to replace the u-joints (front and rear shafts) twice so far! I had vibration occur at 40 mph and higher. Replacing the u-joints fixed the issue. The fact that you could get movement at the joint using just your hands definitely indicates a problem. Replacement of the u-joints should fix the issue.
I also went ahead with a proactive fix for the radiator/transmission issue. I wasn't having any problems but wanted to take care of it before it cost me a fortune. I bought an aftermarket radiator (Sherman) from Rock Auto and replaced it myself for a total cost of only $175. It was a bit of work but hopefully I will be set.

I think I can do the radiator myself also but the flush concerns me a bit. I looked over the procedure in the service manual and it looks like it involves draining from the coolant line from the tranny while filling? Did you end up flushing the fluid as a precaution? I can do a drain and fill but the flush procedure makes me a little nervous.
