Thread: New Transmission cooler line options

Murphy's law hit me bad. I replaced all hoses on my Disco. This included the tranny cooler lines from the auto to the cooler in front of the radiator. I took them to a local hydraulic shop that replaced hose and o-rings, but used hose clamps not swagging. The hose let go after 1100km, out of mobile reception. 6 litres of Transmax Z on the highway. So opinions: remove lines again and get new hose swagged, or buy OEM replacements? It's worth noting that the passenger side line has a bend moulded into the hose. Without this bend there may be pressure placed on the connector at the cooler. Also, how many psi do these lines typically deal with?

I just replaced mine after having the LHS one at the pipe crimp blow off dumping 3.5 litres everywhere. Got the hose back on the line and was holding with a hose clamp until I got home and had time to work out what I was going to do.
Luckily I have a watchdog temp sensor fitted so was able to pull over when it started screaming thus saving an expensive G/box replacement. When I removed the original LHS hose from the cooler this joint was about to fail as well. The RHS line crimps were ok. I replaced both with new lines, good for another 10 years...
