Montana 3840 Shuttle Shift

[Sjake01]

Hi guys, I purchased this 3840 recently with around 3800 hours and am going through it to make it mine. Can someone point me to information or a thread that indicates lubrication type and filter numbers? I want to service the shuttle shift gear box and not finding the recommended lube for it. Thanks ahead! Shaun

Operators and Service Manuals both do not specify for the gear box. Basically everything on the tractor is Universal Hydraulic Fluid aside from the Axles which are SAE80 gear lube.
