But the tranny seems fine just due to the fact that it works fine under hard acceleration. I am thinking that there may be some sort of vacuum leak or something but I really don't know what to look for. She is a single mom raising 2 beautiful girls and loves her Honda (it's her first) therefore I am hoping that it isn't much to fix. Thanks,
