Try giving the MAF a clean. A dirty MAF has been known to affect overdrive :)

It's best to use carburettor cleaner :)

...you don't need compressed air either, the carb cleaner will evaporate after it's cleaned the tiny wires ;)

Is your speedo working OK?
A faulty Speed sender can cause this

possibly, or a wiring loom problem, can you get it OBD scanned?
Failing that it might be worth changing the gearbox oil and filter
