Getting the roll pins out is a real problem for replacing the planet
shafts with a special hardened and ground bolt/planet-shaft.

I think a hypodermic needle and high pressure oil might work.
Put the needle all they way down in the bottom and apply a shot
of high pressure oil to the needle. In theory it should pop out some
what.

I also thought about tapping  it with a 2-56 tap.

Then there is supper glue and welding wire but you have to get all
the oil out first.

Here is another idea. Stick welding wire in and apply a lot of current.
The welding wire might then weld itself to the roll pin. Then pull it
out. This trick might work the best and is easy to try on the junk
planet carrier I have. Are you up for this test Ed?

Using the welding trick has real potential.
Insert the welding rod only into the roll pin about 1/16th of an
inch. This should reduce the possibility of the roll pin welding it
self to the

  planet carrier instead of the roll pin.

Something as simple as a 12 volt car battery should put

  out enough current to weld the wire to the roll pin.

  As a dentist, the first thing I thought about was if I could use
my dental  drill somehow... If the roll pin is not much more than
3/8" deep, I could  just create a small slot opposite the existing
seam, running the entire  length of the pin, then try to grab either
of the two resultant halves with  needle nose or even try the screw
trick again.  Might be able to create the  slot with a dremel etc

The high pressure oil reminded me of how to get out a clutch pilot bearing
if you don't have a puller.  Fill the cavity with grease and use a
pin or trans input shaft.  Hit with a hammer and replete as
necessary.  Hydraulic pressure forces the bearing out. The drill end
of a drill bit may fit closely enough.

Just listen to jean and Paul. Sometimes the best solution is a smart
application of an "educating iron" read hammer. Those pins are hard and will shear easily with a good smack. Quick and easy.

What blew me away is they will shear off in an aluminum planet carrier.
Just a small dimple in the aluminum. Old 4 planet carriers are a dime a dozen. Good source of cheap shafts, needles and gears. Millions of these Ford C6 based trannys have been manufacture over a period of 50 years.
