For the engine about 30 seconds. You only need to get the oil pressure up and that happens pretty fast. For the transmission, it should be at operating temperature so about 3 to 4 minutes should be enough.

I want to check the level of atf temp in my subaru forester 2010. On checking the transmission fluid level, after the car was driven about 10 km and was put in each gear and setting the select level in the "p", do i have to turn off the engine or idle the engine before i check the atf level?
Did you try checking the idle adjustment screw?
From what I can tell from checking around the Internet, your scan tool should read 0 degrees at idle for a 98 GMC 4.3 vortec. If your scan tool is reading anything else at idle, you probably want to have your mechanic check the vehicle for loose or worn parts.
You might try checking you idle air control valve.
I would recommend checking for codes before you do anything else.
The idle speed is computer controlled on a LT1 engine. If it is a little high, try checking for vacuum leaks.
With any turbo it is a good idea to let the engine idle briefly before turning it off. This allows the turbo to slow down before losing lubricant. If you don't let it idle it probably won't hurt anything, but over time it may cause the turbo to wear out faster.
Idle should be between 500 to 750 RPM.
3 minutes.
