I'm a long way from being an "expert", but I have rebuilt a few transmissions with "generally" good results.....and as no one has answered you.....
I first look at the bushings...is the metal smeared/obviously damaged, overheated, signs of foreign material contamination or anything that does not look "normal"? If any of the things above are present, I'd replace. Assuming "normalacy"(a weird term to use on this website!), I try to "mike" the Id for roundness and size....this could be as simple as using dial calipers...or can be difficult, requiring inside mikes, snap gauges, bore gauges or other measuring tools most don't have. Bushings are cheap/cheap insurance.....WHEN IN DOUBT REPLACE...
I keep seal/bearing drivers of various sizes...made from different SCRAP materials.....I have only a FEW professionally made drivers..left over from M'cycle mech days, mainly...Lots of times I end up using sockets....if you choose carefully, often one will work for a driver....use as soft a hammer as possible to be easy on the socket....or if you have a press.....Lots of times i go to scrap pile and find an old piece and use bench grinder and remove material until correct size...yes I have a lathe...but usually faster to use grinder and works ok...
Even with correct tools, you have to get the bearing started straight and keep it straight...watch what you're doing...
temperature delta helps on difficult jobs (not usually necessary on trannys)
might be easier to take case to someone and let them press it in for you...I dunno....
hope this helps...
