Automatic Transmission Control Module problems of the 2008 Nissan Pathfinder

While driving, the vehicle started to stumble for a second, then all of a sudden felt like it had almost no power. Wouldnt accelerate well, didnt shift normally, and didnt feel like it was running as well as normal. When we parked the vehicle, I turned it off to hopefully "reset" whatever may have malfunctioned. When I tried to restart the vehicle, it wouldnt start. The starter wouldnt even try to start the motor, like it wasnt even getting power. Being a mechanic by trade, I jumped out to see what was going on, and had my wife try to start it while I watched & listened. . . As she turned the key to start it, I could hear the starter relay click to send voltage to the starter, but the starter wasnt responding. After further examination, I found a blown fuse in the fusebox under the hood. It was the "a/t ecu" fuse. This is where things get bad. I replaced the fuse to get us home, but as soon as we got home and shut the vehicle off, I tried immediately to restart it. Again, nothing happened. . . No crank, no start. Same fuse was blown again. After a little research, I found that fuse is on the circuit to the transmission control module. This module had malfunctioned and now blows the fuse every time it is replaced. That led me to drop the transmission pan to check it out, and what did I find? transmission fluid all clouded up and contaminated with radiator coolant. How did that get there? after inspecting that, I found that the radiator had failed and allowed coolant to mix with the trans fluid. This coolant is also damaging the clutches in the transmission, as it causes the vehicle to put extra stress on them due to the way the vehicle shifts now. Then I realized numerous people with Pathfinders, titans, and many Nissan vehicles had the exact same problems. Now I'm upset because I have a truck with an expensive problem that Nissan should be liable for, and should fix.

Turned a corner, driving below speed limit on city street, all lights within the dashboard that should have been off (4wd, service engine soon, etc. ) went on, and all readings that should have been on went off (odometer, and so on). Stopped at red light; turned off vehicle hoping to reset before driving home and it would not turn on; lights, radio, a/c were still active so it was not the battery. Only able to shift to neutral with vehicle off to roll to a parking space on the side of the road. No previous issues or warning prior as I perform regular maintenance as recommended by dealership - happened suddenly. Had to have it towed to dealership the following day as it was already after midnight. This followed two attempts calling my warranty company and being disconnected; ultimately called family in the area to assist who helped me rolled the vehicle into a parking lot across the street. After tow and diagnosis, dealer found failure in the radiator (leaked coolant into transmission) and there for failure of tcm (transmission control module). Dealer claims no recall prior to this incident yet there was a class action lawsuit for this exact recall and model in the national database when I researched further after the extended warranty adjuster denied my claim for coverage. This process alone took 7-9 business days; I have been without my vehicle for 3 weeks.

The contact owns a 2008 Nissan Pathfinder. When the contact attempted to start the vehicle, it failed to start without warning. The vehicle was towed to an independent mechanic where it was diagnosed that the transmission control module failed and needed to be replaced. The vehicle was not repaired. The local dealer and manufacturer were not contacted. In addition, the contact stated that the tire pressure monitor sensor (tpms) indicator illuminated. The tpms was replaced, but the sensor illuminated again a few weeks later. The failure was not diagnosed or repaired. The failure mileage was approximately 85,000.

Radiator leaking causing tranny to fail, after tranny is replace the transmission control module starts failing in just less than 2 years causing the car to have tranny issues again Nissan should be accountable for all this defects on this car, it posses a safe issue because transmission control module makes the car run if this fails while car running a huge accident could happen.

Recall investigation #dp12004 : transmission control module failed during motion, causing my Nissan Pathfinder to stall and completely turn off in the middle of the road while driving in heavy traffic.

My wife was driving our 2008 Nissan Pathfinder when her service engine soon and 4wd warning light came on while pulling up to an intersection. When she pulled away from the intersection the vehicle moved very slowly and would no longer shift. After shutting the vehicle off it would not start again. A transmission shop has tested the transmission fluid and found glycol contamination from the transmission cooler that has shorted the transmission control module. The vehicle requires a complete transmission rebuild, new tcm and a radiator bypass to remedy the problem. Total cost will be approximately $4000.

Car would not accelerate from a stop it was as if it was not shifting to first gear from a stop. Also while driving the car would begin to shudder violently and would not stop until the vehicle came to a complete stop. As it turns out, a line inside radiator coming from the transmission broke and caused contamination. Coolant mixed with transmission fluid created a sludge that contaminated both coolant system and transmission. Radiator was replaced and coolant system flushed as well as transmission flushed. A week later the car was parked and would not start. As it turns out the transmission blew a fuse and was not registering that the vehicle was in park. This is all related to the same problem the transmission control module (tcm) was burned out from the sludge created by coolant and transmission fluid. So now, either the transmission needs to be replaced because the clutch and gears are potentially burned up or the tcm. With just a tcm there is no guarantee that the transmission will not fail due to no way of knowing the condition of the clutch and transmission gears. Vehicle is still in the shop for over a month now and we have been forced to purchase a new car to meet our transportation needs.
