So I split our 5420 at work to replace a broken park pawl in the tranny and found these pieces laying in the bottom as well. I cannot seem to locate where they go or where they came from. I've searched through the parts diagrams for the tranny as well as the rear diff and hydraulics to no avail. Local JD dealership can't find them either so I figured I'd give it a shot on here and see if anybody recognizes these parts. It's a power reverser transmission with MFWD. Thanks

Could the shaft part be related to the rockshaft control? Ref p/n R105155 ??

:welcome: to TBN

Does the upper left part shown come apart? The pic is a bit blurry, but some different angles on the pic may help decipher it.

A bit scary to find extra parts lying in the tranny bottom.

It's not anything on the rockshaft nor the #13 in the pdf. Those are all intact. The nozzle looking piece is one piece, hollow and pretty thin and the bushing seems to fit on the end of it. I forgot to mention also that last year when I changed oil in the trans/diff I found a small spring that I now assume went with these parts.

Is it possible that part circled in blue could be it? It is the only thing I can think of. Not sure of the purpose of this. It is a poppet type valve, but cant find a mention of it in the tech manual.
