Since my initial post I inserted the FWD fuse. With the fuse installed I don’t get any binding and I don’t get the code 24.
Now what?

The situation is difficult to logically explain. The solenoid valve C is normally closed, so that when not energised full line pressure results in a closed centre clutch and binding. When energised as result of inserting the fuse, the valve is opened thus reducing pressure and releasing the centre clutch, i.e. a logical and normal outcome.
This then makes the TCU or associated inputs/sensors and circuits suspect. But why no relevant codes? However it does appear that the TCU is not providing proper control and opening of solenoid valve C.
In view of the transmission change, connectors and wiring must be suspect.
