Another mystery transmission

[45bradb]

I’ve killed a couple hours sifting through the “Google” before I ask here but I’ve got nothing. What I do have is a 727 with castings I can’t figure out:
2892754-2 (above shifter linkage)
2392 90L2622 5158 (pan edge)
CE41G9C188246 (passenger side pad)
Does anyone recognize this? Many thanks
