R35 Limp

Hi everyone, I got the 2009 GT-R, it threw some ECU codes P0797, P0840, and transmission codes P0840, P0797, and went into limp, only 1,3,5 and reverse, and speed limited to 30km/h, I cleared the codes, worked fine for about 10 minutes then popped the codes again, But the brain twister, I was taking it to the workshop, so I cleared the codes to allow me to drive it, drove it to the workshop that's about 40 minutes away, perfect drive, no codes, Then went out with the technician, I drove while he monitored live data on his own scanner, I got to 240km/h in an attempt to stress and force the codes to pop, nothing, even love data was perfect, Drove it around all day today, nothing at all, Now, I consulted with the GT-R specific workshop head at Nissan, he said I need to replace the Oil pressure sensor located inside the transmission itself, and some O rings and seals, and maybe a solenoid or two, However, he also said that since the codes disappeared, it may have been an air bubble that just passed through naturally, I'm honestly lost, do I replace them or just wing it and hope for the best ? Note that the car has less than 39,000 km on the odo "real", and has been serviced strictly with OEM parts I personally ordered from Nissan Japan, not dealers or aftermarket, even the transmission oil, I bought that 20L drum from Nissan amd did an oil change about a year ago "less than 1,000km so far", The car is kept at stock, no tuning or modifications whatsoever have ever been done on it, Anyone had the same experience, and what did you do ? I attached a picture of the codes I got using my cobb Thanks in advance for the help
