5HP24 Transmission Rebuild

I am in the process of rebuilding a 1999 XJ8 transmission.

(5HP24 Serial #0168984 Model #1058 000026)

The functional check (ZF manual page 3.7/2) of all six clutch/brakes by applying compressed air to an adapter plate is very disappointing.

Clutches A, B & C. are not functioning.

Brake D has a faint clunk with a faint hiss of air escaping air.

Brakes E & F appear to be functioning correctly.

Any assistance with resolving these issues would be appreciated.
