Hydraulic oil

Where do I add the hydraulic oil to a 154 lowboy at? I would like to drain and refill. Can I use generic hy-tran from the farm fleet store? I am assuming there is a drain and fill plug. I looked through the online manual but cant seem to find anything but total capacity.

drain is on the bottom of the transmission, fill on the back plate

Thanks much. I am assuming regular hy-tran would be ok for oil.

Yes, either the real stuff of equivalent.

Hy-Tran Ultra is worth looking for. Good stuff!

There is some TS hydraulic oil that surpasses the hytran oil.
