On my HD4 I lost reverse - when taking the shuttle valve apart - one of the springs was broken - not allowing the proper movement of the internal valve to line up with the proper port - I matched up a spring in my junk spring collection - trimmed it to size with a grinder and had it back in service on the job in about 2 hours . 
 That small slide valve needs to be centered over right ports to apply hyd pressure to clutch pack .

Any springs broke in the valve ? there are plugs on the front of the shuttle valve that is operated by the lever, the plugs can be removed one at a time and insert a pressure gauge to see what is being transmitted from the pump at 1500 rpms.

The springs looked fine.what pressure should I be looking for? I really think something, somewhere is stopped up. The shuttle shift valve is getting warm within 2minutes of running. First thing in the morning, I'm going to let it warm up and follow the hot lines until, hopefully I find a cool spot and that should be my blockage. I just hope it's somewhere outside of the transmission.hopefully it's a collapsed hose.

there is a filter in that system - also I believe a suction screen - don't have the circuit picture and memory is a little foggy on full routing - believe the filter was to front of machine (steel lines)

Yes. I have a new on waiting on me at the parts store this morning. I cleaned the old one yesterday. I haven't checked the screen yet. This maybe the problem.Its located on the left side of the transmission under the machine...... I think. I'm not looking forward to checking it. I pressure washed the dozer and it's a muddy mess under there.lol

It was pretty dark in the shed it was parked in and I didn't notice it has a prolonged parked mark on the dipstick. I wonder if it's possible that it's low enough to show full on the cold mark when running because it isn't priming the converter..... I hope I worded this so everyone can understand what I'm thinking. I'm going to wait 6hours and check it and see if it is full.

It only shows to be a quart low.so, the pump is definitely putting it somewhere as soon as you crank it, because the fluid drops probably 3inches on the stick immediately. I'm back to a blockage.... . I hope....

From that description, I'm thinking it works like an automatic transmission in a car. Are there places on the transmission to attach a pressure gauge?
On a non-working automatic transmission, one of the diagnostic steps is to put a pressure gauge at specific test points. Typical automobile transmission that I work on has 4 test ports.
