My manual which doesn't mention my model which I believe is an 881 since it's a red belly with hash marks and 540/1000 ground speed doesn't seem to have the fill hole for the transmission. My manual shows it to be above the filter and rearward of the round inspection plate about halfway up the round cover. I suppose I could take off top cover and drill a fill hole or do same with the round cover. Anybody know on the location??
 
The tranny is filled through the level plug. This is to prevent overfilling. Many folks will install a 90 degree elbow in the fill plug hole to aid in pouring the oil into the tranny.

The fill/level plug is located just in front of and slightly below your right foot rest. No reason to go messing around trying jury rig something and really mess something up.

Your manual sounds like it is for a later model SOS and is not appropriate for yours
 
I'll look again on the right side and the elbow sounds like a good idea. Think I read where it takes around 12qts.

Which models does the manual mention?
 
My manual list 501,600,601,700,701,800.801,900,901,1801,2000,4000. I filled the tranny with a flex hose and that fixed both the movement and the pto problem. Noticed the fill plug on the rear along with a level check plug lower down an decided to check that. Drained out about 4 gallons over full! Plan is to pull off fel and paint. Shifter is off and PO put on vise grips to shift. What's the fix for this cobble?

OK, those are not models. They are tractor series. Your 881 is a model within the 801 series, so the manual should should cover most things, but the S-O-S transmission went through some changes over the years and the '01 series models frequently had their S-O-S transmissions replaced with an updated design, and if that is the case for yours you would need the S-O-S supplement for the 2000/4000 series tractors, as that is where they introduced the updated design of the S-O-S.

Still shouldn't be telling him the info he quoted on the fill plug. That didn't change from '59 thru '64.

2tractors, an 881 is an 801. 801 is the series. 881 is a model within the 801 series.

There should be a T handle on your PTO cable. It is pinned to the slider with a tiny steel pin. Likely, the only way you'll find the handle separately is in a salvage yard, if there even.
 
(quoted from post at 08:43:09 11/20/19) The sos shifter is cobbled with vise grips clamped on to move shifter.

Yes! You already said that. You just didn't say what they're clamped to. I only assumed they're clamped to the slider that is in the dash. Are they clamped elsewhere, like to the cable at the transmission cover?
 
Larry, he's talking about the shifter handle being missing and you answered with something about the PTO handle, so that is why he reiterated that it was the shifter handle that was missing.
 
Forgot to add that the shifter housing is probably there and it's just the handle that's missing so the vice grips are probably clamped to the post that the shifter handle would normally be screwed to.

My bad! I read PTO rather than PO in the post and got myself distracted. All he should need is the lever, the shift cover and the retaining screw then. I see both the lever and shift cover quite regularly on eBay.
 
I'll look and see if what they have is a fix for my problem. I have the shift handle and the covers but one side has some kind of nut or center piece for the handle and the other doesn't. Being left handed I would rather put it on left but not sure which part is stripped just haven't had time to look. I'll do that today. Thanks to all you guys for getting me going.
 

If the center shaft does not protrude from the shifter on both sides , it is broken.

There are also used shifter assemblies on eBay. They are a bit more pricey.
 
Just talked to PO an it's the splines on the shifter that are stripped, Is this part something that a weld would work? Also he said it's not the original transmission and it was bought new and replaced an only had about 20 hours, no way that's true with the looks of that filter! Maybe drill and pin the shift handle to the spline.
 
I take it the subject of this conversation is a missing SOS shift lever, among other problems. I just replaced the lever on my 871 this summer 'coz it was worn enough that it overrode the stop screws for quick reversing. I do a fair amount of R1 to 5th gear work, and a new lever fixed that. My point is, this lever still works and if the O.P. wants it, he can have it for shipping.

I'm in mid Michigan and Email should be open.

If the guts of the shifter are messed up. as it now sounds, I believe I'd buy a replacement shifter assembly. The part that's stripped is not weldable material. It's some kind of aluminum or pot metal.
 

If you have the handle but have vice grips to do the shifting it sounds like the cover is missing.
The shift lever fits in a notch in the cover, the cover is what rotates the shaft to shift gears.

Cover should look like this.

A spring goes in the bottom hole to keep the shift lever from flopping.
I'm not able to attach a link to section (07D12) of the parts page the shows the breakdown of the shifter.
