No such thing on an electronically controlled transmission. This uses shift solenoids, not modulator valves.

Hello, the 2003 impala's dont have a transmission modulator valve. this transmission is electronic controlled by the power train control module. the transmission uses a pressure control sol. inside the transmission instead of a vac. operated modulator valve. if you are having a late harsh shifting problem, this would be more in the area of a pressure control sol. at fault

they all pretty much look like this, and just one screw holds them down
SOURCE: Where is the modulator valve for a transmission on a 2003 Chevy Tahoe located
It doesn't have one, the transmission is 100% computer controlled.

Who told you that one ? Module ignition modulator 2003 Chevy Tahoe ! No such thing! Your best bet would be to take your vehicle to a qualified repair shop .
The electronic ignition (EI) system is responsible for producing and controlling a high energy secondary spark. This spark is used to ignite the compressed air/fuel mixture at precisely the correct time. This provides optimal performance, fuel economy, and control of exhaust emissions. This ignition system consists of a separate ignition coil connected to each spark plug by a short secondary wire. The driver modules within each coil assembly are commanded ON/OFF by the powertrain control module (PCM). The PCM primarily uses engine speed and position information from the crankshaft and camshaft position (CMP) sensors to control the sequence, dwell, and timing of the spark.
