Default O/D light flashing

Hi everyone
I hope I'm post in the correct section!
I have a mondeo 2 lt automatic,has 99k on the clock.
Now for my problem, when the car is cold ie. 1st thing in the morning it runs like a dream, changes gear very smoothly however when it's up to temperature the O/D starts flashing and gear changes become very erratic sometimes car goes to 4,000 rpm before it will change to 2nd.
I Would be very grateful for any advice.

Thanks in advance

Get the gearbox oil and filter changed first, a lot of auto box issues are down to contaminated oil and clogged filters.

The oil does look quite clean and the car seems to have a good service history!
Do these gearboxes have a good lifespan?

Yeah they are pretty good if looked after, but they do get slow and jerky to change when the oil gets old, as the oil gets hot it thins right down, sounds like your oil is breaking down with contaminates as it warms up, which is why it is ok when it's cold.

It might not be the cause but I certainly would get it done just to rule it out more than anything as it's what most garages suggest you do first anyway.

il get it booked in ASAP
Would there be anything else I should change at this point?
Also do you think it's ok to drive it?

It should be ok to drive for now unless you are planning massive mileages. Just get the gearbox oil and filter changed first and see what happens. If the problem still persists then I'd have a mechanic look at it again as it's pretty much impossible to diagnose over the internet!
