The Mas Air Flow sensor is located on the top of the throttle body. If you open the hood and look at the throttle body in the middle front of the engine you will see it. Very easy to access.

The MAF (Mass Air Flow) sensor would be found in the air intake snorkel between the air filter box and the throttle body.
MAF (mass air flow) sensor is present only on V6 engines. If you have one of those, you can find MAF attached to the intake tube.
The Manifold Absolute Pressure (MAP) sensor is located near the throttle body on the intake manifold.

To check the mass air flow (MAF) sensor on a 1997 Cadillac DeVille, start by visually inspecting the sensor and its wiring for any signs of damage or loose connections. Use a multimeter to measure the voltage output of the MAF sensor while the engine is running; it should typically vary between 0.5 to 4.5 volts depending on engine load. Additionally, you can use a scan tool to read any trouble codes related to the MAF sensor and monitor its live data for proper airflow readings. If the sensor is faulty, it may need cleaning with MAF cleaner or replacement.

Yes
To answer directly, yes. A bad MAF sensor can affect a computer-controlled transmission if the transmission control computer uses the MAF signal to determine shift points.
