Transmission Cooler Line Repair

I'd like to have a buck for every foot of "transmission cooler hose" I sold over the 30 years I worked in the transmission parts business. Use the proper hose and it'll last forever. Back in the day, I put a cooler on the daily driver. Drove it for 10 years and never had a problem. Using vacuum line hose, water pump hose and you're looking for trouble. It might be all right for a very quick patch, but that's all.
Transmission cooler hose was made to be used with obviously transmission oil.
