well the OP never clarified what even really happened, but we are all assuming he went for an oil change, but somebody drained the trans and then filled the engine back up even though it was never drained to begin with.

So he left with a half drained trans and a double filled engine.
the engine oil over fill isn't the major issue, it's the trans with no oil.
That's why it would rev super high before slamming into gear. It had no oil to pressurize it's valving.
