Re: how can i fix the pump or the torque converter inside...
Is there any oil in the transmission
unless you have a dipstick ( GMC products are normally sealed ) it is very possible that there is no oil in the transmission
the transmission oil pump is part of the transmission around an input shaft and requires the transmission removal for repair / replacement
take it to an accredited transmission service center and have it tested and properly diagnosed
a 6ya Mechanic can help you resolve that issue over the phone in a minute or two.

You need to remove the transmission to do this. Remove the inspection cover at the junction of the engine and transmission to get to the bolts to disconnect the torque converter from the drive plate (the part with teeth that the starter engages). Remove the driveshaft, then the transmission. The torque converter will come out with the transmission. Pull the old torque converter from the transmission, and install the new one. Ensure the torque converter goes all the way into the transmission/hydraulic pump. Reinstall the transmission, ensuring that the torque converter is still free to turn during the entire installation process, especially while drawing up the transmission to the engine. Once the transmission is bolted up, reinstall the bolts holding the torque converter to the drive plate. Reinstall the drive shaft and the inspection cover.
If you haven't done any major mechanical work on a car before, seek the help of someone who has. You will need a hoist or a jack and jack stands, and a good set of tools.
Yes, most likely. The linkage needs inspection from the shift lever to the transmission. You may have to check under the vehicle for disconnected linkage AND under the cover of the shift lever inside the truck.

If this has an automatic transmission then the torque converter lock out switch/ solenoid may be bad? It may have not unlocked the torque converter and therefore when you put it in gear the transmission is locked into the torque converter, and will act like an manual transmission when you forget to push in the clutch to stop. You will most likely need to have it scanned, or if you can locate the switch, try unplugging it and see if the vehicle will run? Most are inside the transmission on rear wheel drive GM products. Not a difficult fix, but messy as you have to drain the transmission and drop the pan.
depends if your car has an automatic transmission if it does the brake light switch signals the transmission control module to Unlock the torque converter ,so the car does not lurch forward if brakes are applyed on fast if its a std transmission no not that im aware of
Sounds like the cable has shifted, from the gear lever to the transmission there is a cable that puts the transmission in the correct gear. this cable is adjustable where it bolts onto the transmission and has probably moved
