The p0720 is a tcm short code, and usually is not caused by the output speed sensor (however, this does not mean it will always be the tcm See nhtsa.gov link below) this a very common issue with these transmissions The project seems complicated, but it is honestly not that. See nhtsa.gov link below) this a very common issue with these transmissions. Hello, i have a customer with dtcs p0720 & p0500 The car will not shift past 3rd gear
I have already removed the valve body and it is coded m3b 2015 infiniti q50 3.7 rwd 7at re7r01a if i enter the vin on infinitipartsdeal The p0720 is a tcm short code, and. You will still seem them on very rare occasions but its largely a non issue post updates. I replaced valve body after getting the p720 code (and not shifting beyond 3rd gear) With the new valve body, the code went away, and the transmission shifts to all 7 speeds However, there is a hard shift at/around 2nd or 3rd.
I know it's actually the circuit board that goes, but infiniti doesn't sell just the board, so you need an entire valve body I am asking, because i did get the dreaded code, had a new valve body installed (direct from infiniti)
