My buddy's Jimmy was doing this when he got it, along with sometimes wanting to slam back down to first when you came to a stop. He didn't have much money to throw at it, so I removed the lower trans cooler line, had him bump it till I had gotten a quart or so out, and then put a bottle of Lucas Transmission Fix in. 17 bucks and an hour later and we couldn't get it to replicate the issues it was having before. Not a permanent solution by any means, but he drove on it two years that way before the tired 350 gave up the ghost.
