2012 NISSAN VERSA with 78189.0 miles

P0846 fluid pressure sensor - replacement of transmission control valve body/ replace complete transmission. I got a check engine light which showed P0846 code in mid 2018. However the check engine light disappeared after a while. The light reappeared now in 2020 showing the same faulty code. I went to dealership to check it out and they said that this is a common issue in Nissans 2012 Versa and that i will need to replace the transmission. They told me that the warranty has also expired as the vehicle is above 84000 miles. ( i got this light at 79k miles with the same code and it had disappeared.) i had photographed it with dates and time showing . Nissan told me that they will not help in any way and that i will need to cover the complete cost. Vehicle works pretty okay i don't feel any issues in it.

On 3/14/2012 (31,604 miles) while pulling out of a parking space the transmission started to grind and the vehicle lost power. The dealer found a stored code r1790 and reset the code unable to find further issue. Picked vehicle up on 3/15/2012 drove vehicle home. The transmission was noticeably slipping and we were told that it was performing "normally" continued driving the vehicle until... 4/18/2012 (33,133 miles) the transmission started grinding again, vehicle lost all power in heavy traffic where my son narrowly avoided being hit head on. Vehicle had to be flat bed towed to dealer, would not move under its own power. Multiple codes found: P0841 left rear pressure switch rationality P0733 gear ratio error in 3rd P0944 loss of pump prime P1790 fault inner after shift P0731/732/734 gear ratio 1, 2, & 4 P0846 pressure switch rationality P0838 lc pressure rationality. Found metal in transmission pan, disassembled and found bad planetary and damaged underdrive compounder. Replaced the compounder, removed the valve body and reconditioned and flushed the cooler. Vehicle was returned to us on 4/30/2012 and still feels like the transmission is not operating normally. *js
