Automatic Transmission Torque Converter problems of the 2006 Nissan Xterra

As I came up to stop at a red light, the Xterra began to shudder and the tachometer started rising and falling until I finally stopped, then the tachometer dropped below 500 rpm and the truck turned off. Restarted it fine, but it stalled again. I quickly figured out that although it is an automatic, I needed to drive it like a manual. So I put it in neutral, started it again, it did not stall, then I revved the engine to 2,000 rpm and put it into drive. Off I went, and it did not do it again that day. However, over the next month it became a growing problem, until it finally was occurring every single time I stopped unless I put it in neutral. I took it to the mechanic who spent 4 hours diagnosing it to be certain of the problem. Which they said was a failing torque convertor and plate. It failed due to coolant leaking into the transmission from a broken housing coming off of the radiator (apparently a very common problem for which Nissan refuses to take responsibility). Not hard to verify their findings due to the presence of pink milkshake looking liquid in the radiator. Final verdict, at best it needs a new torque convertor and plate, but with the amount of effort to install those and unknown further damage from the coolant leak, a new transmission was recommended.

The transmission started to slip, turns out the atf was contaminated by the radiator failing and leaking coolant into the transmission. This was determined by the dealer and of course it was out of warranty. I replaced the radiator and the transmission is being worked on by a transmission shop to the tune of several thousand dollars. The contamination ruined at least all clutch plates, the bands, and the torque converter.

The contact owns a 2006 Nissan Xterra. The contact stated that while driving approximately 60 mph, the vehicle began to violently shake and was hesitant to shift into the next gear. The vehicle was taken to a dealer where it was diagnosed that the torque converter needed to be replaced. The manufacturer was not notified of the failure. The vehicle was not repaired. The approximate failure and current mileage was 95,000.

My 2006 Nissan Xterra (purchased new in Feb 2007) began occasional shuddering, as if driving over rumble strips, while driving at about 131,000 miles. If I let off the gas or accelerated, it would stop, but no constant trigger. This increased over a couple weeks so I decided to research online and found many users with the same issue. I took it to a mechanic and they couldn't get it to replicate. I left there and drove to trophy Nissan in mesquite and they wouldn't look at it for another 1. 5 days and only after I payed them an $85 diagnostic fee (to look at something that is there fault!) I decided to be proactive and replace the radiator and hoses, hoping to catch it early enough. I took it to a mechanic 2 days later. They said the rumbling was from a torque converter lock-up and we could do a flush but that may not fix it. So, we flushed it with 12 qts new Nissan transmission oil. The problem seemed to stay the same over the next couple weeks and then the transmissioin went out on my way home from work. So, now we get to replace the transmission. I called a transmission shop, (at this point I don't trust Nissan or anything they say - since they can't even admit fault on this!) and they said this transmission is an expensive transmission (with it's computer etc. ) so just to rebuild it is going to run $2500. Nissan wants $4400+ just for a new part. This is ridiculous. This was very dangerous as mine completely went out when I was in the middle of an intersection. I am so disgusted at Nissan and their lack of morals / values. If they would just do the right thing and fix the issue that is their own fault, then I think everyone would feel completely different. They need to stand behind the product they sell. As of right now, I will never buy a Nissan again. Why is there not a defect investigation with as many people that are having these issues?.

My 2006 Nissan Xterra started shaking violently while driving at 40mph all of a sudden, to the point I thought I hit something or was dragging a branch, I stop to find nothing and kept on driving, and the cart did it again, so scared of going any faster and loosing control. I took it to the dealership and they informed me that due to a design flaw cracked radiators are causing coolant to leak into the transmission and mix with the transmission fluid. Once the coolant (antifreeze) is in the transmission it kills the valves, seals and torque converter and eventually renders the entire transmission useless. It seems to be a common occurrence on '05-'06 Xterra. But I was never informed nor other Xterra owners. To correct this I have to replace the radiator & transmission at an outrageous price. Although Nissan hasn't conducted a recall or acknowledger theres a problem, they did extend the power train warranty from 60k to 80k. My vehicle has 94k miles, so I'm hoping my extended warranty covers it. This is very dangerous, imagine driving at 60mph and loosing control due to strong shaking. I just cant believe with the overwhelming amount of people complaining they haven't started a recall.
