P0753 means your powertrain computer detects a continuous open, short to ground or short to power in the circuit to your transmission's 1-2 shift solenoid. When the code is active, your transmission runs in a fail safe/limp home mode that only lets certain gear ratios function in the transmission.
The solenoid in your application looks like this
and it is located sometimes on the side of the transmission, but my guess is from the looks of it, it might be found inside the transmission, only accessible with the oil pan removed.
The problem might be the solenoid itself, or the wiring going to the solenoid from the computer that controls the transmission, or the computer itself.

The shift solinoids are mounted to the valve body which is behind the side cover of the transmission. Usually you have to lower the trans to remove the side cover, which envolves lowering the subframe. If you drop the subframe the steering rack must be disconnected and the engine must be held from above because most of the motor/trans mounts are on the subframe
