Transmission Control Module (TCM) (LS4)
Left front of the engine compartment, near the left headlight assembly .What engine does your vehicle have ?

LS4
Engine - Gas, 8 CYL, 5.3L, SFI, Aluminum, Cylinder Deactivation, GM

I'm going to take a wild guess an say you have 3.8l

L32
Engine - Gas, 6 Cylinder, 3.8L, SFI, V6 L32
Engine - Gas, 6 Cylinder, 3.8L, SFI, V6 Supercharged, GM
, GM

If it's the 3.8l L32
Engine - Gas, 6 Cylinder, 3.8L, SFI, V6 Supercharged, GM you don't have a TCM module . you have the PCM

PO128 -- engine coolant low or thermostat not working
P0440 - EVAP system malfunction, gas cap loose - Cat convertors missing from car can cause this
P1189 - Engine Oil Pressure Switch Circuit -- CAT CONVERTORS MISSING FROM CAR can cause this.

There is no special type, so whatever you may find at most stores or gas stations will work.

th fuel pump relay is mounted on the right side of engine compartment by the strut tower

(2) Fuel Pump Relay

that's an easy one..
