If it's a 1500 then yes the 4l60E tranny is for you. If it's a 2500-3500 you'll need a 4l80E. The 80's are only used in trucks with a gvw or 7200 and greater.

The 04 SIERRA is behind a panel with 4 screws under the glove
box...Remove the screws and cover and slide it out.There is actually 2
in there and it is easy once the cover is off.
Usually there are extremely detailed instructions that come with the new filter when you open the box...Follow these instructions it shouldn't be too hard.

I have the exact same truck and the same problem. I have been told that the valves and sticking and to try a GUM-OUT type product before spending that much cash. I don't know how a Fly Wheel can cause that but, maybe. I have also been told that the springs/valve rockers may be worn out.

There is a solenoid that open and closes with 12 volts, usually located close to the fuel filler tube area. This open to allow you to fill your tank, then closes after some inputs for the computer are satisfied, and then a pressure sensor verifies the system is working. First, make sure the cgas cap is tight, and if the light doesn't go away in a couple days of normal driving, get the solenoid checked.
