The hose that rubbed through was actually replaced this year, and routed the same as the old one. I had a hard time finding any half inch hose rated for transmission cooler duty. Apparently the new foreign-made hose does not have anywhere near the abrasion resistance as the original hose. Last night I picked up some 3/4-in corrugated split tubing to surround the entire hose to prevent any more rub-throughs.
