2015 F 350 DRW, Diesel 230,00 miles and transmission lines are leaking. I can't quite figure out where the leak is happening, there is ATF running down the oil filter and on the front of the oil pan. I have not been able to find any information on how to replace them. Would like to know how much of a pain it is to see if this is something I can tackle myself. Are OEM preferred as a replacement or are people going a different direction with custom lines and fittings??
More than likely the leak is at that metal clamp in the last picture. As far as getting OEM lines, good luck with that. If you are good at bending tubing and have a double flare kit, you can cut out the bad sections and fit in a repair section.
Looks like your Orange coolant is leaking rather than transmission fluid.
x2 - that's coolant
Pressure test system with engine off to see where leak is - or see at least see what reservoir bottle is low - the large primary or the much smaller secondary. The two systems are completely isolated but that will get you 1/2 there on where to look. Coolant can run all over the place, especially from driving.
