Dresser td8c transmission troubles

Good morning, hoping to find some help with a problem I'm having with my dresser TD8C. Once the machine warms up and you start pushing hard (blade full of clay) the dozer will jump out of gear. It will do it in any gear, its just as if you throw it into neutral under load. Once you bring the machine back down to an idle you feel it jump back into gear and away you go pushing again. If I'm not to hard on it it doesn't come out of gear but as soon as there is a big enough load it will do it again and again until the load is lessened (lift the blade). All fluids and filters check out, my gut is telling me I have a worn Shift spool and high pressure oil is getting behind it and pushing it out of gear. I should mention that the shifter it self never moves, and it doesn't appear to start doing this until the machine has been run for 30-40 minutes. Any help or direction to look would be greatly appreciated.

The oil streaner in front transmission should be plug by some small metal from oil brake and transmission you need to drain the oil compartiment and flush the oil lines but am't mechanic men
