I would suggest getting a second opinion. But without mentioning it. Some cars have systems that decrease power to cylinders to prevent overheating. It is possible to still do damage even if your not overheating.

Is it a transmission or coil or fan clutch problem?

the fan clutch only runs the fan when the coolant temperature gets hot and has nothing to do with the gear box.. I suspect that the noise is from a faulty front input shaft bearing in the gear box or as I read it a faulty torque converter if it is an automatic. I think that you should go to an accredited service centre for a proper diagnosis before it breaks your bank as from what I am reading , the mechanics you have been going to do not have sufficient knowledge to fix your fault

The parts prices are $36 thermostat and depending on fan clutch model $88 - $260 From autoparts warehouse site
which leaves $580 for draining system and replacing parts and refilling system plus time a bit steep
get another quote from a different mechanic and decide

02 envoy, 6 cyl, loud wooshing noise when engine is cold. fan clutch seems fully engaged. goes away when engine warms up. is this normal or does fan clutch need replaced

Fan clutches for Envoys and Trailblazer are a problem, they go out all the time.

However, it is normal for it to do this when cold, but will only stay engaged for maybe 15 seconds AFTER you've put it in gear and have started to drive. After this, it will disengage and allow the engine to warm up faster.

If you haven't already replaced the fan clutch once, you're lucky. 2002 is especially bad for the clutches, but all years don't last long. Mine lasted 90k which is pretty long.

2003 GMC Envoy Service Engine light on. OBD2 Code is P0128

Ah the famous P0128.....It's 1 of 2 things. If your fan is not engaged constantly (would sound like an airplane or big rig everytime you step on the gas) and is working properly, that rules out the fan clutch. The other common problem is the thermostat. Replace the thermostat and the code will go away. Engine temperature needs to be at 210 degrees on these engines. If the fan clutch is constantly engaged, it's cooling the engine off constantly and won't get up to 210 fast enough. If it's the thermostat, it's stuck open and isn't allowing the coolant to properly heat up in time.

I unplugged my fan blade clutch on my 2004 Envoy because when turning on the heat or a/c truck would shut off. Now that fall is approaching, i need to get to the root of the problem. Is it the Fan Blade...

The throttle body needs to be cleaned, grime in this area prevents the throttle plate from closing completely and allowing air to enter, making the air/fuel mixture lean.
Keeping the fan clutch from working can lead to overheating conditions and it will set your check engine light.
