Sounds like the TCC is engaging and disengaging constantly. Could just be a loose connection at the tranny (doubtful) or the TCC solenoid acting up.

You may have a bad vacuum diaphram, pull the vac line going to the tranny plug both ends and test drive it.

Are there any check engine lights on if si that will help you alot?

it sounds like it could be a bad throttle position sensor or something but it would also act up at idle and you would notice a hesitation off the line as well
