auto leveling... in 4-5 second cycles I hear a pisst/whirr sound and the engine lowers rpms when it cycles.

The CH7 fluid is below the screen whe off but wondering if this is normal. Fluid is not real dirty, belts tight pump dont get hot either. Is this normal? If not what do I look for, havent pumped the **** outta the brakes and checked it yet as it is on ramps for me to finish the suspension replacement.
