What P0700 means
The official name, 'Transmission control system, fault present', is a pointer rather than a measurement of anything on the engine side: the engine computer is passing on that the transmission control system reports a fault present in its own memory. Whatever was measured and compared to set it happened inside that transmission module, and this code carries only the flag, not the figure behind it. So one P0700 read here can stand for a longer list held in the transmission module, which the standard engine-side connection does not reach.
This is a standard code. It means the same thing on every make of vehicle.
What the program shows for P0700
Look up a code names this one with no vehicle attached and says it is a standard code, so it means the same thing on every make. On the Trouble codes screen the line beside CHECK ENGINE reads the lamp as on or off, then the stored count and the total read.
The program has no transmission readings over the generic connection: no fluid temperature, gear, or input and output shaft speeds. It names the code on the Trouble Codes screen, shows Engine speed and Vehicle speed side by side on the Dashboard and records both through a drive for replay, and the freeze frame tab, When it happened, lists what the engine computer stored at the moment the code was set. Compare between two recordings shows whether the code is Gone, New or Still there.
