it probably requires that your old valve body be removed for the parts in the kit to be installed. i'm pretty sure it doesn't require dropping the tranny but you'll have to find an indy that is willing to install the kit for you as i doubt that a dealership would perform this service. if it works, it's a good deal because a rebuilt valve body is about $400+.
