I have Autometer gauges in my truck(ultralites) and have never had a problem. I have recently installed a set in a buddy's truck(same gauges) and his trans temp gauge is fogging up if it's cold outside. I don't have a trans temp in this truck(6spd) but did in my 97 and never had this happen. Has anybody else experienced this? He has a trans and pyrometer gauge with the trans gauge being mounted in the top position on the a-pillar.
