Just for those of you that replaced your tranny and radiator after the seal broke destroying them. If Nissan did not properly flush the coolant system your engine hoses will eventually get soft and become comprimised by the petroleum base in transmission fluid. I had to get all of my hoses replaced and my new radiator was all gooed up with a substance a thick as Vaseline......it was the material that had been disintegrated from the rubber hoses. Keep an eye for this as it takes about a year to manifest after your transmission gets wrecked. Oh and for the record, the guys at hilltop Nissan in NJ when mine went a couple years ago "claimed" that the situation was unusual and not a defect. Bunch of liars.

phxmotor is clearly connected to Nissan. Disgusting to even reply in this way with this dangerous huge problem. As you wrote the majority of us had no idea of the problems until they happened. I am warning people now. There is a woman who works downstairs in this office building. I had no idea which office and because her hours were different from mine I never had a chance to see her. I was tempted to leave my business card on her car with some of the information just to forewarn her. I finally ran into her one day and asked her to email me. She did and I sent her this site, the lawsuit info and more. She is so grateful. She has three sons who just received their permits and the intention was to let them use the Nissan Path for training. As she said there is no way they would be able to control the SUV if it lurched like ours did in traffic. All that saved us while going over 40 in heavy traffic was my husband quick reaction and great driving skills. phxmotor (motor???), you picked a lousy place to spout off on. Kick us when we're down already. Great way to PO all the thousands even more. Pathetic POS!

If the settlement is approved, which clearly shows Nissan admits they know this is a huge problem no matter what they try to claim in the lawsuit settlement, then why are they waiting for failures instead of fixing the problem. Are they waiting for someone to die? And if it is so easy to fix as phxmotor claims then why isn't Nissan doing it?

Gas gauge stopped working, O2 sensor causing check engine light, tire pressure light won't go off... worst of all, my drive shaft cracked while I was driving it, which caused the transmission to crack. Pulled over immediately. waited 3 hours for tow. Nissan dealer said its not covered under my warranty. Insurance is only paying $10,000 for it, as it was a total. Still owe lender $4000.

Ok but if you make adjustments to your car like that does your warranty get negated? I feel like Nissan would take every opportunity to cancel your warranty if they can.
#1187 of 1246 Chronic Nissan Problems

I bought a new Nissan Pathfinder in 2006. Nissan has had the reputation of building quality products in the past, and that was a huge factor in my decision. At about 55,000 miles, my fuel gauge stopped working and the check engine light came on. I researched the problem and found that this is a common problem. Nissan had issued either a warranty extension or some sort of recall, but never notified owners of the faulty fuel sending unit. I had to purchase a new one from the dealer at an expense of $100.00 + labor.
Soon after that repair, the check engine light came on again. This time the code was for a cam sensor, again not covered by warranty. I am only acknowledging this repair to show the pattern with this vehicle.
Next was the catalytic converter. This was at around 80,000-85,000 miles. I started to wonder if the years of building top level vehicles was over at Nissan.
Which brings me to the problem I have now. Nissan apparently noticed a pattern of transmission cooler failures causing coolant to mix with the transmission fluid causing failure in the transmission as well. There is no external leakage, so if you don't know about the problem from another source, the only sign will be when the truck breaks down. I took my Pathfinder to a repair shop and was told $2000.00 to repair the transmission in addition to the new radiator and trans cooler.
There are numerous forums online with people having this same problem. Nissan extended the warranty for the radiator, but not the transmission. They also deny any manufacturing defect and I received no notice about a warranty extension. Consumers have to be made aware of these bad business practices because manufacturers will not change if we are ignorant of their tactics.
#1188 of 1246 2005 Pathfinder shudder problems--Proper Flush
Mar 09, 2013 (4:38 pm)
2005-10 Nissan Pathfinder, truck, and any other similar problematic automatic transmission.
My wife’s Pathfinder just had the “Shudder” problem. With only 76k miles on it I was surprised that anything was wrong. My wife described the problems EVERYONE has complained about on the blogs.
I was able to recover our Pathfinder without much problems. Now I only have basic mechanics know how but enough to not pay an mechanic for SOME things—I am not a transmission technician!
However, I want to make sure everyone knows how to correctly FLUSH YOUR AUTOMATIC TRANSMISSION with better then average success hopefully –this is what I did and have found:
1. After the radiator has been cooled (actually cold. You can get burned if you open the radiator cap when hot – caution!)
A. Open the radiator cap and see if there is any contamination of any kid. Big or small contamination should be noted. Flush your radiator and related items (over flow) thoroughly and add new anti-freeze (50/50). Make sure you use “green” anti-freeze to distinguish between other liquids.
B. I replaced the radiator cap. If it is defective the coolant will not have the pressure inside the radiator to circulate the water cooling properly and may run hotter than normal or over heat. Now food for thought. If the water over heats, will this cause the transmission heat exchanger’s o-ring to break giving you transmission/coolant contamination? Stant part number “10233” only cost me $8.55 with tax. Good insurance at a low cost! I have seen other people replace on a vehicle’s water pump, belts, ratidator, anti-freeze to only find out the problem was the radiator cap that they needed when the vehicle would over heat. Trust me the quality of Nissan’s original cap is at leat questionable. When you see the replacement you will see the difference.
2. Drain your Transmission fluid (screw available).
3. remove Transmission pan and oil filter replacement. There is aprox. 16 #10 screws on the filter.
4. Look inside the transmission pan for metal filing or similar –take a picture for future reference.
A. If it looks sort of silky it is ok or I should say it is normal to have real fine silk like material at the magnet area located at the bottom of the pan. You may be in good shape to continue with the process and “probably” be ok (silky). This is what I had.
B. If you have “metal” filing small and of big sizes. Ouch! Probably evidence of major problem. How can I give you a picture on the difference? Remember in high school science class with the metal filing and a magnet, if the metal filing are similar to that or bigger you may or may not benefit from the flush. I would save the used transmission fluid and I would filter it with a lint free cloth or similar for use just in case (you don’t have anything to loose).
Note: I have read and heard that if the transmission has less then 80k miles you may do a flush with NEW fluid without any “slippage” problem. However, if you have over 100k miles and never done a transmission oil change that you are better off not doing a flush. But you should remove and water out. I would save the old oil for reuse if there is slippage. How do I do this (moisture removal)? Let it sit in a transparent container (dry 1 gallon water contianiner is what I used) and the water will fall to the bottom or slowly boil the water out. Use Sea Foam may be better.
Notice even if you have just a bit trace of some mixture-- remove.
5. Carefully replace the transmission filter with a new one (save that one for future reference if you are to take it to the mechanic). Mine was NOT clogged I reused it. (Clean it first though).
6. Replace pan gasket and fasten the screws. Actually I reused my factory gasket, but recommend a new one—at least on the last flush.
7. Place an external transmission oil cooler if you are in an hot area BYPASSING factory radiator (junk) cooler or replace radiator. Note: It is a known fact that the cooler the transmission oil is the longer the transmission will generally last.
8. Now the most important part to me with THIS transmission (or contaminated xmission) is that you have other goodie that most transmission do not have—more on this later. I have read all sort of GOOD advice about the transmission/anti-freeze mixing (contamination) and their symptoms—get familiar with them! But I have not seen (or I missed it) on what to do if you have contamination OTHER than flushing or I should say IN ADDITION TO flushing for this transmission!
Well it is important to remove ALL humidity out of the transmission system, including the torque converter, valve body, etc. One important information that you should know about this transmission. The Transmission Control Module is located within the valve body. How crazy is that! A computer like device. One of the things that kills electronics is high temperature. Now electronics require connectors in order to communicate with other devices external to them. Water (anti-freeze or “contamination”) is another thing that is not good for comunications, so if water is in the transmission you need to get it out. Two ways to remove water out. 1. remove the transmission out and open it out. This is where I would pay a transmission technician for. Or 2. Chemically remove water out. I used SEA FOAM Trans Tune. Why? It is a conditioner, cleans gum and varnish, REMOVES MOISTURE, smooths rough and erratic shifting in automatic transmission, cleans and DRIES hydraulics. According to Sea Foam …”Trans Tune breaks moisture down into molecules and disperses it throughout the system to aid in faster evaporation”… There are other products, but I would only use a product that will concentrate on moisture removal primarly and I would NOT use stop leak additive since may cause other problems down the road!
Now more on why moisture removal. You see this transmission has some electric contacts inside the unit and solenoid/relays in addition to TCM. This is an electrical/mechanical item may not work properly if contaminated. You may get intermittent shudder problems. Now if the relay activates, but may not move entirely mechanically speaking you may get intermittent shuddering symptoms. Maybe, just maybe this was partially what I had. No codes, just shudder at 5th with low load at about 40 MPH. If I accelerated, it would stop, same as other wrote on blogs…
In my case I did have slight oil contamination in the RADIATOR (barely caught it) I did NOT SEE any in the bottom of the trans oil pan. Though it does not mean there wasn’t any inside the system! At approximately $4.50, good insurance not expensive.
9. I added Sea Foam Trans Tune, and 5-6 quarts of transfluid with the addition of the oil cooler.
10. After slow driving as low as 10 miles I noticed reduced shuddering and after 25-30 miles the shuddering problems had go away! I wanted to make sure I went some distance to evaporate any humidity in th

Mar 17, 2013 (5:57 pm)
I had my 05 pathfinder fixed for this issue at around 75k at a local shop that is not a "Nissan Authorized" service center. I wonder if they will reimburse for the repairs since I was unaware of this at the time. Since the settlement didn't exist there was no way I would know it has to be repaired by a Nissan authorized center. Anyone heard of people getting reimbursement for this type of situation? -Doug
