    Tranny hard lines don\'t fit into new radiator

    My top tranny-to-radiator hard line is way offline with the installation of a 4 row 454 radiator. Can I remedy this by putting a tranny cooler inline with the rubber hoses? I was going to do this anyway. What else can I do?

    Thanks

    Yes you can run rubber hose for the tranny lines. I dont know if it is recommended but you can. I just noticed that both my lines have been cut and patched that way. I have only had the blazer less than a year and that's something I plan on changing soon.

    I did that to adapt my lines to the tranny cooler. Had one of them pop on me on the street, darn near caught on fire since the spray was aimed directly at the manifold. Luckily the huge cloud alerted me to the problem immediately : )

    I SHOULD run some type of solid line, but I must like to take chances. Then again, just about everyone else does too. Don't waste time with cheap braided line either. Either go quality braid or hard lines. Rubber doesn't like oil, and tranny fluid is hot oil. (hydraulic fluid, ok) If you put some braid over the hose, you won't see the hose deteriorating until its too late.

    I did something like that. What I did was turned my old AC condencer in to a tranny cooler I got my hose from NAPA at about 4.50 a foot I bought twelve ft. of the stuff too. I used all but 6in or so. The hardest part was getting the right fittings. But it works. Maybe this will help somewhat.

    Just so you guys know, most aftermarket tranny cooler manufacturers suggest that you run them in series with the factory cooler in the rad. For those of you in warm climates, like Texas or Arizona, it's not as important, but for you guys who actually experience cold winters, an aftermarket cooler by itself can actually OVERcool your fluid......

    I disconnect my aux. cooler between November and March, BTW.

    As long as I run the tranny cooler in series, does it matter which hard line I connected it to? I needed it because the top line wouldn't fit, so that's the one I connected it to, without trying to find the correct in or out line. It might not cool as well connected in the wrong order, but it should be okay right?
