Every morning when the truck is cold, the trans does not want to shift out of 1st gear. After about the truck warms up, the trans shifts smooth up and down gear all day long, and does not slip.. The fluid looks great.. Any ideas? I'm wondering if it's a modulator of some sort, or i'm just got getting that much pressure.. i'v heard good things about the transmission seafoam.. worth a Try?
