Fuzzy logic?

My fiancee says she notices that the transmission feels as if it's in "neutral" (or slipping) when she attempts to accelerate onto the freeway after rounding the apex of an on-ramp. This is an E-shift model and she obviously has it in drive when this occurs. I've never had this happen when I drive the car. Two questions: 1. Has anyone ever had this happen to them? 2. Might this be related to: her lead foot and the LSD kicking in or the fuzzy logic of the auto tranny?

nothing fuzzy about it... 2001 is300s had a problem where the traction control was set too agressively. there is a tech bulletin that explains this. basically, take the car into the dealership and they will update your trac and flash your ecu.
