i know its not nearly as good as having your tranny rebuilt . i think bully dog might have a kit with springs to increase line pressure . does this really do anything or is it just a gimmic ? will it hurt anything by doing this ?
thanks

Everyone here says there crap. :badidea: There really are no bargain trans. upgrades that are worthwhile. Anything that is worthwhile requires pulling the trans. And while you have the trans. out you should go ahead and upgrade the converter as well.
