I have a '92 F250 4WD with a 7.5L and E4OD. I want to install an aux trans cooler. I plan to put the new cooler in-line with the fac cooler. The install has to be able to take severe vibration from off road use. I'm looking at the Tru-Cool 4590 because it fits in the space below the fac cooler (12x12x1 1/2).

My dilema is that I do not want to use rubber hoses to connect the coolers. I prefer a steel tubing set-up. Is anyone aware of a Tru-Cool model or comparable "stacked plate" design that can be plumbed this way? I've tried in vain to get the info from Tru-Cool (Long Manufacturing) by phone or website and most of the web sites don't offer this configuration. Fact is I can find only one Tru-Cool dealer in my area and he wants over double the on-line price for the 4590.

Thanx....JQ

If you have a shop in your area that makes hydraulic hoses, you can have braided hoses made in any length, pressure and fitting config you want. IMO, that would be better than hard pipe.

In the FWIW department, I make steel lines out of brake tubing to run right up to the cooler from the tranny. I do not know about the more modern trucks, but the older automatics will take a 3/16 fitting. You have to put a few bends and curves in the lines and not run it straight through, if that was even possible. Double flare the hose end. Next I use a very short piece of that expensive tranny line from the hard line to the cooler in a place where I can easily check it.

Good advice. If the cooler takes -AN fittings, you can go to Earl's web site and find local dealers to make custom hoses. Also, they can do extended brake lines.

 

I use 5/16 steel brake line. The kind with the steel coil over it.
Takes lots of vibration and the added coil helps with contact on other metal parts. Plus it bends real easy.
