You'll have to disconnect all cables and wires from the transmission and transfer case (if applicable). You'll need a transmission jack. First, you disconnect and remove the driveshafts. How you proceed from there is up to you. You can remove the bell housing, transmission, and transfer case (if applicable) as a single unit if you have an adequate transmission jack to do it. Or, you can remove the transfer case, then the transmission, then the bell housing. However, then you replace the transmission, you'll want the bell housing to already be mounted to the transmission.

Yes you can, It's the same thing. As long as there both 2-wheel drives are 4-wheel drives.
No you can not. The 98 computer is not programed to shift the 89 transmission. Besides that your wiring harness on the 98 will not hook up to the 89 trans. You need to go back with the factory 4L80E trans. That belongs in the 98.
