Manual states this Warning lamp will flash and the alarm sounds if there is no, or low oil pressure in the transmission. Unit will still move. Manual shows use 10W-30 Engine Oil. Is this correct? If I fill should this stop the warning and alarm?
 
You need to replace the hydro oil pressure sender. Remove the right side engine panel and right below the hydraulic filter the sender is sticking straight out at you. It has two terminals on it. 10W30 oil is correct.

Thx Mike10, disconnecting the wires did stop the alarms. Can the unit be operated with this disconnected until the part comes in to the distributor? Would be an estimated run time of 10 hrs...

In 99 out of 100 times you can probably run with it disconnected with out a problem. The question is are you willing to take that one chance that something is indeed wrong. These senders are known to fail especially the older style. If you run it just be alert to any change in the way the loader drives or noise coming from the hydros.
