Never heard of this, I would think something is getting water in it that shouldn't be. They are electronic so I'd start looking for a bare wire or maybe water is getting inside the computer.

Just thinking but does this happen only when it is cold or all the time. Toyota's and I mean all Toyota's will not shift into overdrive until properly warmed. All of the Auto Toyota's that I've owned including my Tercel, both Camry's and both 4Runners did this.

If your thermostat is stuck you may not warm up enough or if the temp is up and down a lot then you could have it shift into and out of OD as it warms and cools. This happened to me on my 86 when I'd drive in snowy conditions.

sounds like you need to go through the connections between the engine bay and the transmission and put some dielectric grease on them.

I would start here or get full control the RADesigns way with a 1-4 shift controller.
