Not sure how close they are to a 735 but we had a few AWR-B1N's in the area have the drive gear for the trans pump fall off, and cause that problem. Unfortunately it's inside the transmission. It's a long time ago, I don't remember the details...
Similar type of "black sand" and "carbon-type" material that you found in the D8T transmission filter..? If the answer is yes then the transmission is most probably coming out just like the tractor.
