No Drive after replacing ring gear.

Hi All
Just carried out 2x replacement ring gears on a H16D 391 & H25D 392. both 2009 models.
When completed and a functional test I now have no drive! Bizarrely on both machines. Everything else working fine but there's a bit of cavitation noise on the drive circuit with very slow speed. Had the hydraulic pump off and then the transmission pump out, All back together correct so I suspect its drawing air from somewhere. Any advise is welcomed.

Sorry to ask but did you fill the hose from the pick up pipe to the pump
If not it will not draw the hydraulic oil up
To much of a head to draw.

Thank Doctor.
Would a faulty speed sensor not display an error code as we have no codes displayed?
