SOURCE: how do you clear a low tire pressure warning on a 2004 yukon

Have you driven the vehicle over 45 mph.? If not, drive 5 miles above 45mph and the light will reset.
You can also clear clear pressure reading by reseting through the DIC, mode and set buttons.
Owners manual will explain use of the DIC ( Driver Information Center)
Good luck, let me know.
Regards,

SOURCE: The Message Center on my 2002 GMC Yukon XL is

the oil level sensor is located in the oil pan. There should be a yellowish/brownish plastic looking large diameter nut sticking out the side of the pan with some wires going to it. Unplug those wires and see if the message goes away. If it does then don't worry about it until you have the means to do so. Just monitor the oil level ever thousand miles or so.

The senors are pretty reasonable priced and available form the dealer. They are threaded into the pan and a medium sized crescent wrech is all you really need to remove and install.

I’m happy to assist further over the phone at https://www.6ya.com/expert/jeremy_d728a59f986299fa

Check your fluid level. The Transmission Control Solenoid may be failing or the transmission filter could be clogged.

Hi what this warning mins ( trans hot idle engine) 2000 yukon 4x4 5.3?

It means that the transmission oil is overheating and you need to cool the oil by allowing the engine to idle for a period of time . The transmission oil cooler is in the radiator and that means that the engine temperature will also be running hot . Check oil level in transmission and adjust to correct level. Check the load being carried /towed as this makes the transmission torque converter work harder and the speed you are travelling at What ever the reason I suggest that you run the fault codes to check for transmission problems

'Transmission Fluid Hot' warning light

Stop using it & have the transmission temp issue
checked out

Ever change the trans fluid since it was new?

Doing it now won't help if debris froze up a valve
or temp switch in the valve body or the valve body
is worn or that model has issues that need to be updated

HOT TRANSMISSION LIGHT FLASHING

When this warning light flashes it means the fluid (ATF) temperature of the transmission have reached a level that is detrimental to the operation of the transmission and damage will occur if the cause is not corrected. The causes can be overloading (towing) the vehicle, severe operational circumstances such as high air temps. Other common causes are excessive slippage of the transmission due to worn clutch packs or a defective torque converter. Also the TFT (trans fluid temperature sensor) can malfunction and send a false signal to transmission control module (TCM) and set the warning light. I would not ignore this warning, have it checked by a transmission shop or the dealer.

Transmission cooler light comes on periodically. When car is allowed to sit for a few minutes light goes out and shifts normal

See 3rd dot point. It sounds like transmission fluid is getting hot and triggering the warning light. Check fluid level. Check trans cooler and cooler lines to be sure trans fluid is flowing through cooler to transmission. Transmission fluid temperature (TFT) sensor
The TFT sensor is located on the internal wiring harness to the solenoid valves in the fluid pan.
It is a resistor and measures the transmission fluid temperature.
The transmission fluid temperature is used by the PCM for the following functions:
  • Applying the torque converter clutch is not permitted until the transmission fluid reaches a certain temperature,
  • engagement of 4th gear is prevented in extreme sub-zero temperatures until the normal operating temperature is reached,
  • if the transmission fluid temperature is excessive, a pre-set fixed shift curve is selected and the torque converter lock-up clutch is closed in "2", "3" and "4"; of the transmission warning indicator is activated. No substitute signal is available for the TFT sensor.
