Long answer; 2000 Siverado 4.8L/5.3L has a Gen 3 LS based engine. The 98 Tahoe had a 5.7L gen 2 engine. the LS uses a top center bolt that does not exist on the 98 unit. Also the LS unit is 5/8" longer than the 98 unit. There will be a lot of driveshaft work to install it into a 2000. You would also have to get a flywheel & spacer. It will cost as much or more to swap it than it would to buy a one that fits. Just a little more to get it built right...

The input shaft is pressed into the input drum. To remove the input shaft, it will require partial disassembly of drum and transmission at this point you may as well just rebuild the transmission.

I understand how tight money can be... I've been there done that, now I'm retired...
The pump is different, The input drum is different, well at least the input shaft is. Changing the shaft requires a press & some way to hold/support the aluminum drum, that way you don't break it in the press. The bell housing is different.
Bottom line is it will cost almost as much to swap the items over as it would cost to fix it.
If you have enough experience to swap all that out, you have enough experience to fix the Silverado unit... You have to break it down 3/4 of the way. If your that far in you would be a fool not to at least change all the seals in the low/reverse clutch. When that is is out you have a bare case...
I've done used clutch transmission job's before, problem is they just don't last. Then your doing it all over again...

4l80e swap So what year model 4x4 4l80e’s can go in a 2000 Chevrolet Silverado 1500 4x4 looking for a little bit stronger transmission 4l60es we’re really bad trannys and what would I have to change in order for that to happen and work or is it a simple bolt up just like the 4l60e

I disagree on the 4L60E being a bad transmission. if you take the shear #'s that were manufactured. Your going to see a bunch of common failures. If you do a 4L60e right and treat it fairly you'll get a lot mileage.
I built one for my son's 2000 Yukon XL 5.3L. He towed a dual axle trailer quite regularly moving cars and trucks to and from. he even pulled 3500 series trucks with it. It was a solid transmission for over 50K. It developed a miss-fire he couldn't find and eventually took out the TCC lining. It's still used as a back up vehicle... I told him to limit hi-way driving until fixed. You know kids, they never listen...
He did finally find the miss-fire, cracked plug. He didn't think that could happen after only 25k on new plugs and wires.

Tahoes, Suburbans and vans switched over to ls engines around in 2000. 2003 for vans.
The main problem is, how do you know the replacement functions properly....
