The problem
THE AUTOMATIC COOLER LINE HOSES ON SOME OF THE SUSPECT VEHICLES MAY CONTAIN MATERIAL VOIDS, WHICH COMBINED WITH A HIGH THERMAL EXPANSION AT ELEVATED TEMPERATURES, COULD RESULT IN HOSE FAILURE AND TRANSMISSION FLUID LEAKAGE.
What owners should do
THE DEALER WILL REPLACE THE COOLER LINE HOSES USING HOSES WITH KEVLAR BRAIDED REINFORCEMENT.
