Joe was a dealership transmission mechanic, and learned that for a period A-904's were valved so that the trans cooler (and thus lube oil) flow was shut off in Park

so when you start your Volare on a cold morning and walk back into the kitchen to let it warm up there's no lube to the bearings.

Thanks Joe! 

This reminds me of the transmission problem of people flat towing a car, and putting it in neutral, which would spin the internals, but not the trans fluid pump, and result in destroying a transmission. 

There's a lot of valuable car guy knowledge that's been lost, and will be forgotten, because cars made since the 80s aren't basic, and all the problems that basic cars had that caused every gas station to double as a service station, employing a couple mechanics, have disappeared, along with service stations. Now the vast majority of problems are dealership repaired, it seems to me.
