Automatic Transmission Control Module Problems of Nissan Sentra

This particular vehicle exhibits a very strong, almost dash rattling judder when moving from the 1st to 2nd gearing ratio. This is especially dangerous in traffic and intersections where the vehicle is known to be in 1st or 2nd gear ratio, as Nissan likes to ratio out their cvt in software through the tcm to produce what feels like shifting from gear-to-gear as in a normal automatic transaxle. What makes this situation extremely bad is that when entering an on-ramp to the interstate (I-20 for example) it will intermittently judder from 1st to 2nd and then no power. After the judder it takes another few seconds for the tcm to figure out what happened and engage maybe more valve body pressure? I'm not sure completely, but it's extremely unsafe to drive. The altima/rogue with the same transaxle and model year run was issued a TSB and subsequently a tcm update was issued to rectify the early shudder, but the Sentra did not receive that update. The tcm output data shows that when this shudder is happening that there is a loss in hydraulic pressure somewhere in the unit. As Nissan says you never are supposed to change the fluid, this creates a very serious issue not only with the transmission, but warranty as well. The safety risk to others is high on this one because this could cause major rear-end conditions and city driving collisions as the car is supposed to be accelerating but can't because the transaxle was slipping and not gaining speed with the rest of the vehicles as expected.

The transmission quit working in rush our traffic in st. Louis, missouri. The incident nearly caused a severe accident, if it hadn't been for two alert drivers during rush hour. After sitting for approximate sixty minutes waiting for a tow truck. Just before the the tow truck arrive another tow driver was going to pick up another vehicle "he stop to help. " the tow driver was going to tow the vehicle. He was testing to see what the problem. As he started the vehicle he put it in drive and nothing happen. After a few minutes it jump in gear. The vehicle was driven home with loosing power, surging, and rpm going up without acceleration. This happen in late November. The car continued to jerk, stall, and loose power over long trips. The car was taken to the dealership but they could do nothing until they put a device on it to read codes. This was completed December 20, 2021, I was notified to drive the vehicle for several days up to a week and bring it back to them. The vehicle was picked up and drove per dealership instruction. The car was returned after christmas. The tech perform a tcm update. They tested and drove the vehicle with myself in the car. The manager concluded the car had transmission problems that pointed to the transmission but it would not reveal a code. Until they get a code or approval from Nissan there was nothing they could. On about January 28, 2022, I was instructed to pick up the car. Also, I was instructed the car was unsafe to drive. It was bitter cold (12 degree) fifteen minutes into the drive home the service manger call (note after hours). The vehicle stalled/loss power and a multiple of problems. Approximately twenty miles away the vehicle caused an accident in which I suffer frostbite and damaged to my left hip. With the assistant of the state trooper I was safe until the tow truck from d and k arrived. The vehicle was towed back to the dealership and remain until present date, james gibson.

The transmission would occasionally slip while in motion during acceleration. When the vehicle was brought into the dealer for an oil change, we brought the issue to their attention. Service department advised that a tcm software update was needed. I located a service campaign bulletin covering tcm reprogram covering 2013 vehicles (sb-10051662-4475). Nissan consumer affairs will not address the 2014 issue at this time.

There is a known problem by Nissan with the transmission shifting hard and incorrectly and not engaging in gear, resulting in the car driving at high rpms, and belt slipping constantly. I had my tcm reprogramed out of pocket because Nissan wouldn't do it, said my VIN didn't fall in the range of recalls on that problem. The tcm was reprogrammed and now my car is worse. I am a single mom or 2, working 2 jobs 7 days a week. I still owe $11k on my car and I cannot even drive it, nor do I have $4500 for a new transmission. If you look online there is forum after forum of this known problem and Nissan is unwilling to assist customers and they say they have the best customer service. I love my car and I am willing to accept a rebuilt transmission but they are unwilling to help me at all. What do we have to do to make this a recall? it is a known problem on many 2013 - 2014 Nissan Sentra's that around 75k - 100k miles the cvt transmission starts to have issues, and that is exactly what has happened to mine. Any assistance would be greatly appreciated.

My auto slipped from park to drive Sunday morning, December 16, 2007 with no warning. We had a terrible snow storm and I had my car in park while clearing the windshield and it slipped from park to drive. This has happened before while driving where it will slip from drive to neutral. My locks also locked as soon as I shut my doors after started my auto. I have power locks and the doors should not have locked with the key in the ignition. I was locked out of my car for over an hour until I could get a tow truck to my home to open my car.
