I added a trans cooler to my truck and deceided to cut the trans line to make a cleaner installation. Everything worked great but I found if I flared the lines there was no way I could get the hose on the line. With no flare it was difficult enough to get the hose on (really tight fit). So I just installed it with no flare and put the clamp on the hose. It seems very tight with no movement or leaks in a couple of days. Should I be concerned about not flaring the line?? Do ya think over time it could possibly work loose?? BTW the cooler is a Tekonsha Defender.

I have had mine installed the same way as you for 2 1/2 years and 42,000 miles. No problems at all so far. I think it will work fine.

 

If you have any leak problems, try sliding the hose on a bit farther and double clamp it. Or scar up the surface of the line a bit so the hose hase somthing to bite into...kinda the same purpose as a flare.

Count yourself lucky. I just did the same thing. I double clamped the hose to tube interface. Took a shor tdrive down the street, no problems. Went on the freeway and goosed it. When I got home I had tranny fluid everywhere underneath. The hose to tube did not leak it was the flared ends of the cooler that gave up. Big mess to clean up. How do you know how far you can go tightening hose clamps. These are very small and I can easily strip them out? Any way I tightend them up some more and am still testing. So far so good.

BTW, I have enough clearance behind my cooler to get my hand back there and I was very suprised to feel how much the air is heated when the fan draws it through after just driving around with no load the parking it.

If you leave it the way it is, that is with nothing for the hose to bite into, you will most likely have a problem down the road. What works well is to take a tubing cutter and etch several courses on the line. Do not cut all the way through of course, just scar the line. This will give the hose something to grip on and you will be able to install the hose easily.

Speaking of trans. coolers, i am looking for one that uses the stock tubing fitting size. Is this possible so as to avoid the possibility of leaks? Plus the installation would look much nicer. Any help would be muchly appreciated.
Thanks!
