My dad noticed some spots on the Driveway when I was home for christmas, low and behold my tranny cooler line is leaking. Truck has 58k on it now, 1st time I've noticed it, fluid is still good, only a tiny leak, but very annoying. Gonna have this, my burnt out HVAC and Steering wheel control lights replaced under warranty as soon as the weather is good enough to drive the beater (and I fix it). GM has always had problems w/ the rubber to metal connections. Anyone ever see oil filter lines on a 4.3L blazer/jimmy that didn't leak?
