If it is running, no. AFAIK, the last transmission with a rear pump was the Powerglide, and I think the rear pump was deleted in about '68.

Putting an automatic transmission in neutral at a light and then dropping it into gear will hurt the trans about as much as putting it in Drive when you go to drive away in the morning, i.e., not at all...unless you are into "neutral dumps".
