Is there any reason why I shouldn't have my local fluid power place put new rubber hose on my existing aux trans cooler? My hose is leaking at a crimp fitting. I mean, they make me new hoses for my end loaders and excavators.
Thoughts?

And they can also do your Oil cooler lines and AC too, just depends on how good shape the ends are and they need to use the correct hose type.

I'd suggest that you stress the importance of correct end placement and not to use the swivel jointed ends as they seem to not hold up and leak.

Jeff,

Just done the same thing on my cooler lines albeit I did it myself. I had the radiator out whilst changing over the cam sprockets so plenty of room to work. Cut the existing crimps out with my Dremel tool and fitted some correctly sized hydraulic hose crimped with quality Jubilee clips [there is not much pressure in those lines]. I tried to collect the AFT that escaped- it was not much at all - checked the oil level in the tranny and it looked perfect so did not add any [I suspect it was probably a tad overfilled to start with].

FYI: Some years ago I removed the cooling loop from the radiator coil location altogether upon a specific recommendation [still no idea whether that was a good thing or not but others have subsequently recommended same and to date no issues but I change the ATF at about half the proscribed mileage]. Did not do this because I wanted to- more that a new radiator I had built for me did not have the in-tank coil fittted due to a communication **** up and I was not goin to send it half way round the world to be modified.

I was thinking about changing the hose connections at the tranny end but that looked a bit more tricky so I bottled out for this year. Careful inspection suggested they were in good condition and to be fair they do not see the heat of the engine or so it seems.

Greg sells a kit with hose and clamps to replace all of the trans cooler lines including the proper oetiker clamp pliers if you don't already have a pair.

My thinking is that when one hose gets old enough to shrink and leak, the others won't be far behind. (This is supported by real world reality.)

My hose is virtually identical (visually) to the original oil cooler hose....just made from more modern materials.

I've been installing this hose and clamps for about 8 years, in house. I've been selling it to others for about 5 years.

So far, haven't had a single hose leak or fail.
