Hi,my name is mike and I will assist you with your question.
From what you are describing this is the overdrive drum piston loosing pressure or the overdrive band is damaged or loose both of these are common to cause the issue that you are currently having.

what is the cure

Expert:  mike_a_mechanic replied 4 years ago.
The cure is to open the gearbox and inspect the band and replace if flaked or scored and air test the drum which will show if the piston is leaking. If leaking the drum has to be replaced.
