Previa transmission slip... very occasionally

Maintenance/Repairs

Hi all. I have been driving my 1992 Toyota Previa alltrac (automatic) for several years now, having previously owned the same vehicle with a stick shift.

Every so often, on the highway, my tranny slips out of fifth (i.e. overdrive) and into what sounds like third. I’m usually pushing the vehicle a little, at fast highway speeds, maybe passing a big rig. As soon as I let off the gas it goes back into the appropriate gear.

(The vehicle has 155K miles, and runs like a top, fwiw.)

Is this worrisome? I have, umm, killed a few manual transmissions over the years, and this is my first vehicle with an automatic transmission. And when I describe its symptoms as a “slip” it’s because this is the only term I know… it might (?) be that at fast fast pedal-down speeds it’s simply downshifting, albeit dramatically.
