Does anyone else have a issue with excessive heat comming in from the firewall/floorboard??? Is there anything I can put like a heat sheild/insulation under the carpet??? I don't want to go crazy and do the whole car or anything, but if there was something I could tuck under the carpet to block the heat from the tranny/firewall, that would be awesome (expecially on my wife's 99 v6, thats even worse....)
