vd8 During flight and especially landing hydraulic fluid transfer from B to A. It became 100 A and 85 B. No leak found

I thought that was normal on 73 classic? Qty changes when gear position changes on A system.

On 73Ng a particular pseu fault can cause the gear transfer unit to operate and send B system fluid/pressure to drive the gear and "over flow" A sys to the point of it dumping the excess overboard.
In the case I saw the PSEU had incorrectly sensed an eng failure.

Black magic in that PSEU ! Be careful.
