Try going for a short drive with the expansion tank cap loosened (yes loosened) so that the cooling system heats up but does not pressurise.
Allow the engine to cool, still with the cap loosened, then top up as appropriate. Then, replace the cap, fully tightened as normal, and continue to monitor.
Some remaining air following refilling as you have done is not unusual for a few days, but it should settle in time.

The coolant level appears to have stopped moving, which is great - must have been some residual air that is now burped out.
I'm also planning on getting the welding at the osr front sill attended to, and have the gearbox oil changed. Amusingly, it is my mobile TVR specialist that has agreed to attend to it - who is cheaper per hour than my local backstreet garage, who didn't fancy doing the welding!

I've never understood the need for temperature criticality when changing the transmission fluid or checking the levels. The Jaguar's using ZF gearboxes were the same.
It's hard to see the need for the complication. The fluid does not change in volume with heat.
For the 75's, I just used to start the engine, disconnect the supply pipe to the oil cooler, and catch the fluid as it came out. Stop the engine when the flow stops. Replace the pipe, then refill the gearbox with the equivalent amount, then run the engine until the gearbox is warm, moving the selector between all the positions. Then, while the engine is idling, remove the level plug to achieve the level.
I never had any issues with this method. Job jobbed!
