Does it drop into neutral as you're going down the road, or in between shifts? If the latter, what gear(s) does it happen in, and is it on up/down shifts, or both?
I'm not as well-versed with GM trannies. I know the non-electronic Ford automatics use a cable mounted on the throttle which regulates line pressure in the tranny. On those if that cable breaks or becomes disconnected, it'll slip when it shifts because there's not enough pressure on the clutch packs. Might be something to check out if it's set up the same way.
