So I answered a guy on another forum that the 727 transmission should be warmed to operating temperature, the shifter put momentarily in each gear, then the gear selector left in neutral at idle while checking the transmission fluid.

I have a feeling a few of them don't believe me....

I was always under the impression the 727 needed to be in neutral because of reduced line pressure in park, the converter doesn't "fill" in park or something...

Is there a technical explanation a layman can understand, or am I cuckoo?

(Don't answer that! )
