Don't be to concerned about the gunk and crud in there. Mine looked the same way, Actually maybe even a little worse, then the final drive gears and carrier. looked as if they pumped pure grease in there. NOW, I didn't find any un-attached parts, but like Mr.HR said, more than likely a poppet ball for the shift detent that wasn't put in correctly. Was the tractor jumping out of gear beforehand?
The PTO bearing has a grease zerk, people have the tenancy to pump, pump and pump more grease than really needed in there, this may be way there is so much gummy gunk all over. PLUS, if you have a tractor like mine hitting the 50 year mark, God only knows what all has been dumped in the gear cases over that long of period of time.
Looking at the picture, even though it had to get a good eyeball view, appears that the gears are still in good shape yet with good "lead-in" Take a good look at your shifting forks and rails. Check your bearings and I will be willing to bet that transmission will give you many, many years of trouble free service.
Like yourself I was worried what shape my gears and the rest of the transmission. So I took everything out cleaned and dye checked every single gear tooth and replace the bearing and any seals and put it back together. NOW, if your not wanting to go to the extreme that I did, I would suggest keep cleaning the complete transmission out and keep washing over and over again. I would use the kerosene first, then I used a petroleum base cleaning solvent. I myself use Safety Kleen
Here's also a trick I have used in the past. I have me one of them "Little Giant" submergible pumps (you can get them at the hardware store for outdoor ponds and fountains and such) put it into a 5 gallon bucket and then fill the bucket up with a couple gallons of cleaning solvent or kerosene. Put a hose on the pressure side of the pump and then using my cleaning brush and with the pump pumping solvent up to the top end, let if flow back out of the drain hole on the transmission and then you have you a portable parts washer. Keep the pump off the bottom of the bucket several inches so it won't be picking up the gunk that comes out. Mine has a filter, to help keep out the majority of the gunk from being re-used. After you have it all cleaned out then, put in clean solvent and rinse it all out. Of course, you can change the solvent as many times as you want,
(IF I REMEMBER CORRECTLY) there is a passage way between the transmission and the differential ,so both uses the same oil. Chances are the differential looks about the same way. It's been a few months since I torn mine down and have worked on other tractors since, 38 years old here and already have CRS
Hey good luck on you transmission, but I think you'll find your transmission is in fine shape, just put that ball where it's suppose to be. IF, it is even suppose to be!
I know that several years ago I was doing an upper end on a old Harley I had. I didn't want to split the case so I just took everything down to the top of the engine block. I thought about stuffing a rag in the top to where the cylinder jug is bolted onto the block. I thought well heck, what are the chances of dropping somthing just perfectably between the flywheels and connecting rod. Well this is where Murphy's Law fell into play. Drop the darn wrist pin keeper went right in. Fished it out with some magnets on a wire and guess what? Not only did I bring back my keepr, but two more. I guess someone else did the same dumb stunt.
