Transmission Line Failure
I replaced the lines to the tranny cooler(aux.)in my '91 Bronco-5.8,E40D in Jan.
Today after a long,hot ride,the shifting was starting to be different than normal.When I got home and looked underneath,I was dropping a lot of fluid from a rupture in one of the lines.Most of the under carriage was wet.I used what the local auto parts store recommended,High Pressure fuel lines.Do you think this was a freak thing to fail so quickly?Or is there a better hose material to use?The lines stand free.No rubbing or heat nearby.
Thanks

Fuel line is about the highest tensile strength hose I have ever used for tranny cooler lines. The next step would be a metal line but I don't see how that should be necessary. You may have gotten a defective chunk of hose. How long is the line in question more than a foot? Less?

Little more than a foot GS.No problem to replace again.Just hope I didn't lose too much fluid.Just had the torque converter replaced last fall.But with almost 17 quarts in the system,I think I'm alright.I'll check it in the am.
BTW,
How have you been?

You are not supposed to use fuel line for transmission lines. The transmission fluid will eventually eat through the lines (as it did to you, but I am a little surprised it did it so fast).
You will need to buy rubber hose that is acceptable for transmission fluid. It will say right on it that it is ok for ATF. It costs a little more but better.
Good luck!

Replaced the ruptured line this morning.Also did the 2nd line.The rupture was on the outside of the hose.Like it bubbled,then came open.
The line I put on today is for tranny coolers,said so right on the package.
Looked a bit beefier.We'll see!
Had to add about 4 qts. of ATF!
Took it for along ride,through town and on the hiway.No shudder,no slip.
Upshift and downshift seem ok.Overdrive too.When I punched it on the hiway
,it downshifted nicely.
Maybe I finally caught a break.This is why I'm sometimes hesitant to do my own repairs.

ok,after that test drive the Bronc sat for a week.Last Sat. when I was adding fluid,I was checking the level with the engine running and warm.Filled till I got the proper level(in the hatch marks).Checked it today(while cold) and the level was high on the dipstick.Thinking I put to much in,I let some out,till I was between the holes(cold reading)on the dipstick.After driving the truck for 20 min.,checked again and the level didn't register on the stick 
According to the manual,checking while cold the level should be between the holes,and checking while hot the level should be in the hatched area.So..
I'm getting the opposite.I'm thinking after it cools down and the fluid from the system and aux. cooler return,I'm getting a normal reading.? is,do I have too
much or not enough fluid in the system??

Are you sure you are putting the dipstick in all the way? Sometimes it can get caught and not go in.
If fluid is low this is what I do. First drive it around a bit to warm it up. Then put it in park and cycle it through the gears. Go from park to reverse, wait for 5 seconds, then to neutral, wait five seconds, then to drive, wait 5 seconds, then to neutral, wait 5 seconds, then reverse, wait 5 seconds then back to park. Then let it sit for a minute. Then check it.
If it is low, top it up bit then cycle gears again. Keep doing that until it is in the hatched area. Also make sure you are on a level surface.
Good luck!

When it was warm it was in the hatched area,when cold,it was higher up the stick.So I let some drain out.Guess I should put more in to get the level to the warm-hatched area.
Thanks
