Anybody experience this with a 46re?

Anyone here have any experience with 46re trans? Its in my 98 1500 4x4. Changes d filter and fluid awhile back. If I pull up to a stopsign, then accelerate kinda quickly, it acts like it spins the tires for a foot or so, but its not! Doesn't slip in any other gear and it pulls fine if I kick it down from a roll. Just feels like momentary tire spin from a dead stop, but its definitely not. Never had an automatic Trans act like this. Thanks
