It REALLY could be. . .

a bad upshift module.

Question: when you drive the car cold, first thing in the morning, does the car stay in first for a few minutes before shifting into high gear?

If the answer is NO, then probably the module is 'gone'. It should keep the tranny in low gear before shifting when the car is cold.

Check it out and let us know.
