Need clarification L295DT Hydraulic Fluid Level

[Desert Sands]

In researching hydraulic fluid levels for this tractor am I correct in that I check 2 different places. 1). The transmission level for transmission and 3 point at plug next to clutch pedal. 2). The hydraulic reservoir at the controls for the loader with dipstick.
Thanks.
