Cowboy, here is some info for ya.
Full-size trucks first received the huge E4OD (Electronic 4 speed OverDrive) transmission in 1989. Internally, it is essentially a C-6 with overdrive added to the front (such as the A4LD is to the C-3) and an EEC controlled valve body.
If it becomes necessary to overhaul your E4OD transmission, you should perform as many updates as possible if it is a pre-1995 unit. E4OD component updates include, as an example, the following items:
Improved (thicker) converter clutch piston (circa 1994), prevents the formation of cracks which relieve fluid pressure from the apply side of the clutch, causing it to slip and even bluing the outside surface of the torque converter in extreme cases. Ensure that your new converter contains an updated OEM or "LuK" brand heavy-duty clutch. This can be difficult, as many torque converter suppliers and remanufacturers may not use this new style of clutch.
Higher displacement front pump (for 1995) provides more fluid capacity for faster engagement of reverse and greater lube flow.
New (for 1994) 4-pinion overdrive planet and input shaft assemblies replace older 3 and 4 pinion units which tend to develop cracks in the carrier under heavy loads.
Center support update kit (for units built from 1989 through part of 1994) replaces wear-prone bushing with a ball bearing and contains a new overdrive stub shaft.
Stronger overdrive clutch cylinder snap ring which will not dislodge.
Revised sun gear and rear case bushings (circa 1992 model year) provide longer wear life and better lubrication.
Four pinion planet carriers (first used in 1992 model year)
New forward clutch friction plates with hardened internal splines cure "chatter" and "no-drive" conditions in E4OD and some later C-6 transmissions.

Try
www.transmissionpartsusa.com, they have real good prices and have not only tool for the E4Od but Sonnax upgrade parts for the pump among other things.
www.bulkpart.com has rebuild kits and small parts kits and upgrade packages to Red Eagle frictions and Kolene steels which are better than the stock setup.
Do a search on Richter69, he has a good pictorial on rebuilding the E4OD, plus good tips and shop built tools which is great. Always replace the output shaft snap ring on the rebuild, the Ford standard number is 387031-S.

The slide hammer can be a universal type as used in body work, you actually are supposed to use 2. One on each side, but alternateing 1 side to side to pull the pump will work. The adapter mates the slide hammer threaded shaft to the threaded holes in the pump. These tools maybe available on the sites mentioned or local. The next tool will possibly be an OTC Ford Rotunda only-- Clutch spring compressor T89T-70010-F. You will also need the gear train tool for disassembly and reassembly. Read further and you will see it mentioned. That tool is available aftermarket.
The missing checkballs indicate you have a later model tranny or a shift kit has been installed. The servo piston also, it was revised to eliminate the plate and snap ring. The snapped shaft is the input shaft and goes from the torque converter to the OD planet carrier. So Far your probably in for replacement of the shaft and OD planet carrier and probably TC due to the metal shavings.
The upgrade info mentioned is correct except the lastest design for the planets is 6 pinion front and rear and 4 for OD all with cast iron carriers. These parts bring strength up to 2002 4r100 Diesel level. Since your fixing it to sell your probably not wanting to upgrade it, just fix it. The ball bearing center support and pump alone will upgrade an IDI tranny to Powerstroke 95-97 strength with the used planets I have. 94-97 diesel units have the same strength planets.
Do not play with your tranny balls.
good chance you will be leaving the tranny in the road with broken parts.
