I had the chance to talk to a transmission expert (works at a repair shop) at the EV association meeting last night.

I described engine off coasting with an automatic transmission. Not surprisingly, he strongly advised against doing it unless the manufacturer specifically says the vehicle can be flat towed. I asked, "even for short distances - say a hundred feet?" His reply: the damage is cumulative.

However he did offer two potential solutions:

1) One was significantly overfilling with transmission fluid (maybe he was joking about this...)

2) The most sensible option was adding an electric pump inline in the tranny oil cooling line return from the radiator. He says RV drivers who flat tow "non-flat-towable" cars sometimes do this, and power the pump from the RV's electrical system.
