Whatever. 20 bucks just waiting.

ETA: There is (or was) an self-described ASE master tech posting on this very site I would not let put air in my tires.

The answer was in response to someone who had accidentally filled his crankcase with ATF. The tech was illustrating that it was not uncommon to intentionally mix ATF and oil, and as a result his opinion was that running straight ATF for a short period was not harmful. I posted it to give the OP some reassurance that it's possible all is not lost.

He may not be correct, just another piece of information to consider that tends to support the theory that this was not a catastrophic event, and that maybe some form of compensation that falls between say $20 and a new engine might make sense. Like maybe an extended warranty on the engine and a sincere apology for the inconvenience. I'd take your twenty but I don't have an FRS. I bought a 2015 for one of my kids because they're inexpensive and looked like fun.
