VT Gearbox staying in 1/2/3 (not overdrive)

My gearbox runs very smooth, all changes are perfect.

I noticed today when driving along a highway (very light acceleration) it stays in 3rd gear (or lower) and will not go into overdrive (4th).

I take my foot off the accelerator and it goes into 4th. Just very lightly touch accelerator and goes back to 3rd.

Turned off car, took key out and now appears ok?????? No codes are showing as engine light has not come on.

Should I be concerned, maybe do an oil change in the box.

She's only got 150,000 genuine on the clock.
