Automatic Transmission Cooler Problems of Chevrolet Silverado

Design failure of transmission cooling lines. Set of three cooling lines failing at crimped joint between solid line and flexible line. This seems to be a common failure due to design, low to medium pressure lines being used in a high pressure system. Failure during operation could result in sudden loss of power or engine braking which may result in vehicle control difficulties especially on slippery roads. This is a high failure rate item according to the service tech/advisor.

6 spd transmission cooling lines leaking at hose crimp by radiator. May cause a fire under hood because tranny oil is coating lines all the way back by exhaust manifold.

I was driving home from errand running and found the brake pedal going almost to the floor. Found a puddle of brake fluid under the truck near the back of the cab and bed of truck. Called my service person and he said it was probably a ruptured brake line, and from the description of where the puddle was it was probably above the gas tank where the line is secured to the frame. He also stated that he has repaired multiple chevy trucks with the same problem. I have seen the underside of my truck and all the lines are rusted, including fuel and transmission cooling lines.
