SOURCE: location of fuse box/panel for 2004 yukon denali xl
There are 2 fuse panels in the Denali.
One is a panel on the drivers side, its on the dash but facing the door.
The ohter is under the dash and above the pedals, this one is much tougher to access.
Your Owner's Manual should tell you where the fuses are that you need to access.
SOURCE: 2004 yukon xl denali self-leveling rear air shocks
There's a lever that connects the driver-side rear shock to the Automatic Level Control module (the air compressor and the ride-height sensor). Disconnect the lever from the shock and rotate it up and hold it. The compressor should kick in when you hold in place after a few seconds. If it doesn't kick in, make sure your fuses and relays are good. Otherwise, you may have a failed ALC module/burned out air compressor (from the shocks being shot). After you replace the shocks (and after you recouped from the heart attack you had when you shelled out $500+ for each shock), replace the ALC module/compressor (it's all one unit), and test it - it should kick on when you rotate the lever up again.
Figure about $350 for the ALC module from your dealer, and make sure the part numbers match! Your truck came with an upgraded ALC module from the 2001-2004 module, which were prone to water damage.
Good luck!

SOURCE: What the normal transmission temp Yukon Denali XL 2008
TRANSMISSION FLUID NORMAL TEMPERATURE IS 200 DEGREES.
SOURCE: How do you change the transmission fluid in a 2004
At the bottom of your transmission there is a large square/rectangular pan (depends which trans you have). Have a large drain pan to catch 5 to 9 liters/quarts of transmission fluid. Undo all of the retainer bolts and carefully lower the pan (this can get messy for the unexperienced) .
In some cases the rear transmission mount may need to be undone and the rear of the trans lifted to allow clearance for the pan to be slid past the crossmember.
Replace the trans filter too!

Only the mechanic that is working on your vehicle can give you a fair labor estimate. There are different things to factor in. The vehicle is 14yrs old. I would guess 6-8hrs. Even though you are only thinking about the transmission. There are other components connecting to the transmission (Mounting bolts, transmission mount, Electrical harness, cooler lines, radiator and U-joints). The mechanic may require a coolant flush and/or transmission cooler and lines flush. I would suggest at least two estimates and go from there. The shop need to see the vehicle, They will not be able to answer your question over the phone.
