hey guys, I have my 727 in my Duster now with a 318 and I went to put my trans lines on but they get in the way of my B&M star shifter, so my question is can I run rubber trans line for the front port or whatever it’s called to the radiator or is that a bad idea?
Thanks, Carson
 
Its Ok,but use hard lines as much as possible. When joining hard to rubber try to flare
the metal line to keep the rubber from slipping off. If you don't flare use 2 clamps
on each connection. Make sure the lines are routed properly away from heat and
moving parts, use the correct rubber lines for AT fluid.
 
Post a photo and maybe we can suggest something. Just went through this with my 727 and Lokar.
 
I wouldn't run rubber. As mentioned, post a good pic or two and maybe we can give you some ideas.

Agree with the above post, but flare the the hook ups , and use two hose clamps . "keep away from heat !"
 
Put new lines on. Rubber will do in a pinch and I've done it temporarily, but these are old and have been cobbled enough.

There are lines made especially for this application. If you stuff a 440 in an old barracuda, w/ 2" headers , and a 3 1/2" exhaust system, things are pretty darn tite , no room for much of anything---------
 
Rubber lines are used on every trans cooler I have used for the last 40 years. Not the most elegant solution, but it works fine. The pressure is very low, but the oil can make them slip. As said above, you need some sort of flare or feature on the tubes to keep the hose from slipping off.

I have used fuel line for years with no issue. Poor people have poor ways....
 
About 5psi IIRC.
Rubber lines often rot from the inside. Pieces separate and make one-way valves. I'm glad you were able to make it work for 40 years, but I'm pretty sure fabricating a steel line woulddabin cheaper.
 
No argument that steel lines are better and preferred. I have installed transmission coolers on my automatic vehicles for years & there is no choice on the rubber hose there. Sometimes I have taken them off the old vehicle and put them on the new one. Never had any issues but those caused by my own incompetence. That was my point.

I know that I get tired on big projects sometimes & just want to get it done. Nothing wrong with a shortcut if it is done right. Sometimes you just need to choose what you spend your time and money on.
