I fixed mine yesterday on my 2019 GMC sierra 1500 AT4 6.2L with a super easy quick fix to get rid of the faulty crimps without replacing the whole assembly. 1- drain your oil 2- cut the aluminum line just behind the crimped area with a angle grinder or pipe cutter 3- debur the inside edge of the pipe after cutting it with a deburring tool 4- flare the ends of the aluminum pipe with a flaring tool 5- cut new piece of 15/32” hose rated for transmission oil cooling (TOC) 6- apply small amount of oil around pipe to allow hose to be slide over the flared ends. (Using a heat gun on the end of the hose for a few seconds made this even easier) 7- slide your hose on and secure with new hose clamps. 8- refill with oil 9- enjoy!!
