What tool is needed to remove the transmission
Professional way? Pilot Bearing Puller. Here is an example,

Not relevant to your situation due to availability, or budget? Then it's time to use your ingenuity.
Non-professional ways:
1.Makeshift a slide hammer puller. A rod of metal with a hooked end, or similar. Attach a large pair of Vise Grips to the end of the rod, place the hooked end inside the inner bearing race. (The hole where the transmission input shaft goes)
Take a hammer and tap on the Vise Grips, so that the rod is pulling away from the bearing. (Towards the back of the vehicle)
Work on one side of the inner race, move over a little, and work on that spot. Keep moving around until you pull the bearing out.
Yes, very 'Shade Tree' but will work in a pinch. (Hard on Vise Grips though!)
2.Use a small flat cold chisel. Hit the inner race of the bearing, knocking it out. Remove the inner race, and all bearings. Take the chisel again, and carefully cut a groove along the outer race, staying Away from the crankshaft bore.
Once, the groove is all the way across the outer race of the bearing, and is deep enough, you can work the outer race out of the crankshaft bore.
If you scar the crankshaft bearing bore, file just the scar smooth, and follow up with Emery cloth.
AGAIN, the above No1, and No.2 examples are Non-professional, use at your own risk. I just thought I would post these methods, as not everyone has $26 to $35, for a tool you may use just one time.
