I need help finding out what is wrong like asap cuz this is my only means of transportation. Thank you
First check the transmission oil level with the dipstick. make sure the truck is on a level surface. there is level lines on the stick to show low and full levels. the brand of oil will not cause this but make sure the oil type is right. it should be a Dexron type oil which is for GM vehicles. if the vent tube for the transmission is plugged it can cause the oil to purge. it could be a hole in the oil pan or the pan gasket is damaged leaking the oil out or even a trans seal is bad.

I'm told and read a sun shell may be broke. Common problem for this vehicle. Shop will possibly rebuild and use aftermarket kit parts to correct problems the transmission had originally. Cost is probably between $1300 to 1600 to repair. Good luck I got the same problem on a 97 Jimmy and 3 shops said the same thing.

SOURCE: power steering fluid leaked out of 2000 GMC Jimmy
well it went somewhere, check all the lines and look for signs of recent fluid leaks, it will be very apparent if u lost that much fluid, most likely it will either be the power sterering hoses or the front shaft seal of the pump.
SOURCE: how do i change the transmission fluid out of my
There are two ways to changing the transmission oil. If your going to change the transmission oil and filter, your going to have to drop the transmission oil pan to get to the filter and the oil will drain from there, but keep in mind that it will get messy. The other way to replace the transmission oil if that is all your going to do is to get a large bucket and a small hose the size of the transmission oil line. You can disconnect the transmission oil line from the radiator on the passenger side and connect the hose to the line and the other end to the bucket. Start the truck and try to do this with two people, one to hold the hose and one to start the turn off the engine when the transmission is almost out of fluid. DO NOT RUN THE TRANSMISSION DRY, so make sure the other person understands you when you tell them to shut off the engine. This will ensure that you replace most of the fluid in the transmission, once most of the oil fluid has been drained from the transmission, just reconnect the oil line and refill the transmission fluid through the oil dip stick. Good luck and hope this helps.

SOURCE: wath P1406 Code means on a GMC jimmy 1996,
It's an egr valve problem (exhaust gas return) egr position sensor.
Take off the egr valve and turn it over and see if there is carbon build up in the ports, if there is clean it out with a pipe cleaner and a little carbon cleaner, just spray a little into the ports and clean it out. If that doesn't cure the problem, then either the sensor needs replacing, and or the egr valve.
