I would say no to the torque converter since the slip would be felt in all the gears, and would disappear with the torque converter locking up Yours is disappearing when the clutch would be released which is backwards. There is a plate inside the transmission with check balls inside if it. It sounds like that plate is worn and a check ball isn't seating properly. When you let off the gas it starts to shift into second and mashing down on the gas is causing the trans to quickly shift back to first and the sudden flow of trans fluid is forcing that ball to seal properly.

Get it tested at a trans shop first but as far as price goes you could pick up a b&m shift kit for under $50 so I'm sure the stock price for it wouldn't be any more. Its a simple task also, drop the trans pan unbolt the valve body and remove it. The link has a PDF that provides full detailed installation instructions, check the link for spaces when you copy and paste. http:// bmracing.com/?wpsc- product=shift-improver-kits- chevrolet-gmc-pontiac-1993-2002- 4l60e make sure you have a trans shop run tests on it first don't just throw the shift kit in.
