TYM 474 50 Hr Service

[Dunkinboom]

Hi Yall!

So I'm approaching my 50 Hrs on my 474-shuttle shift.

Operators manual says Engine oil/filter, Trans/hydraulic fluid and front axle oil drain/refill as well as other checks. TYM website says only engine oil and filter.
I have taken filter interchange numbers provided byTractor TYMe on this site. I understand Rotella T6 5w40 is better for colder climates. I cannot find what type fluid for the front axle. 80w90?? and does the trans/hydraulic fluid take a special tractor fluid? Is 37 qts accurate for drain/refill? I reached out to my dealer last week and have not got back to me.
Can anyone chime in for the specs??
Thanks

My new Holland Boomer 50 hour was engine oil and filter, front diff oil (went synthetic gl5), hydraulic filters and top off hydraulic fluid lost during filter change. Hydraulic fluid full change at 300 hours.

Standard 80w90 GL-4 for the front diff is fine and is really close to 2.1g. Being you have the shuttle shift, don't know if tranny is in the same pool as hydraulic system. I know my HST takes 9 gallons of J20C compatible fluid.
