sluggish in 4 on the freeway

got a 350 mated to a sm420 4 speed w/ granny gear in my 4x4. down shifted into 2nd on accident and got a temporary 7.5k on the tach sounded baaaad. then on the way home i'm driving fine on the street through 3rd gear, then the freeway and as soon as i hit ~60mph my motor became sluggish, down to third...still sluggish...back to the street and fine even in high rpm in lower gears. also fine in rpm range in neutral. chime in?
