Hey new to diagnosing issues on these types of machines. Have done a torque up test and the shaft keeps spinning. seems to be losing trans fluid somewhere and will not move period. Have determined its on trans side but that is all. any suggestions or direction on which way to go would be appreciated.

Can you post a Serial Number please.
At idling speed does the shaft never stop spinning at all when you engage any gear - forward or reverse.?
Again at idling speed, does the shaft give any sign of even slowing down at all over the speed it turns when the trans is in neutral.?
You say that it "seems to be losing trans fluid somewhere". How did you determine that.?
Also have you tried adding some extra oil to the transmission and see what happens.?

When in neutral the shaft spins and continues to spin no matter what gear it's in. The spinning accelerates when you idle the engine up but never stops. The reason I say it's losing Trans oil somewhere is it was full on Friday and yesterday we had to add 3 pails and it didn't show on the dipstick at all.

Do you have access to pressure gauges.? I would suggest as a first step to check the transmission pump pressure. To find the spec would require a Serial Number.

To answer that question requires the Serial Number so that I can look at the manual. There are quite a few different iterations of D8T so knowing exactly which one you have could be critical to tracking down the correct information.
You are going to have to have enough oil in it , should be pretty obvious where its leaking from at that volume of leak
