Rubber Trany lines????

[67chevemall]

I just bought a truck with rubber trany lines(looks like FI fuel line)
Isn't this a bad idea?
To much flex no?
I took the AM trany cooler off with rubber lines but the main lines are replaced with rubber too????

The rubber tubing must be the type that is made specifically for use with transmission fluid. If anything else like just regular fuel line is used the rubber will deterioriate quickly... The flexing issue should be no problem as long as the lines are secured from touching anything hot or rubbing on a frame rail.

I walked 16 miles out fo the Desert in 105 degree weather because of Rubber lines.... Change them !!!

There are lines made for this aplication. I have some on the one ton that are rated at 300 PSI and designed for any and all oils. Used with the proper fittings, they are bullit proof.

You ned to determine what exactly you have, like Ron said, if it is the wrong stuff, it'll make you walk. I've been there myself.
Do you have a digi cam?

Ya there gone! I don't like the looks of em.
I see fuel line on one, and walking in the oposite of the desert is no good man.
burrrrr.......sleep..

i had to cut my hard line tranny cooler... when i got my new radiator becuase they dont make a 12 inch cooler anymore ( or so i was told) ... im using the special tranny cooler rubber hose and a couple hose clamps holding it together .. seems to hold up just fine

[68gmcdually]

I would be changing them as well, ASAP or wait until the temperature rises a little, it has been awfully cold north of the border lately hasn't it. Coming down to your neck of the woods over New Year's I hope.

I bought an external tranny cooler from Summit Racing. Within two months the rubber lines SUPPLIED IN THE COOLER BOX failed. They left me and my brand new Triton stranded on the side of the road until my wife could come and save me.

I have since replace 90% of those lines with metal. The connections are rubber. I carry a spare quart of tranny fluid and a hunk of replacement line in the tool box so the next time one breaks I don't have to call for help.

There was a recent article in a magazine about this. Someone makes a kit that includes a tapered-barbed connection that is placed on the cooler/tranny/rad that accepts the appropriate rubber tranny hose and solves the most common problem of the hose coming off the connection (no matter how many hose clamps you use). Anyone know this article?

I did the dumb hoseclamp/rubber line on my 76 chevy. I realized too late that the hard lines go between the engine and motor mounts, and couldn't snake the new ones through without removing the motor (for the 3rd time). I got lazy and clamped rubber hoses to the cut-off hard lines at the tranny/radiator. Long story short, the hose came off the radiator and sprayed tranny fluid onto the headers. Not a pretty sight.

Since then I've heard that the rubber lines can expand/split from the heat of the fluid. My next project will be to learn how to bend/flair hard lines

[67chevemall]

robert just get a flare tool kit, and a big pipe to bend the lines on! It is quite simple and a whole lot better than rubber.

[Longhorn Man]

what robert describes is what I have. The Parker store makes them. I just went to there WWW, but can't find it on there...they need to update there site.

i used to do alot of v8 s10 stuff before i got into these trucks and i ran a few with rubber lines and never had a single problwm. here`s the tool i use to flare the hard lines with and it works just fine.

For anyone who has trouble with hose clamped lines popping off of a tube, do like I learned to do on airplanes.

Take a double flaring tool set and do the first flare, but not the second step to complete the flare. It leaves a bead around the tube to give the hose and clamp something to bite onto.
