Well, I've had 3 lines blow and a Ruptured Radiator to show for it.
Since then, I've Bypassed the Radiator completely with the Tranny lines
and have had NO Cooling Issues nor overpressured Lines to deal with.
That's why I went with the Steel Braided Lines and AN Fittings.

 

I use rubber hose rated for Trans and Oil lines. Constant tension clamps work the best.

 

Got my Goodyear hose last night as well as fuel injection style clamps. There were a lot of good options posted here, but this was the easiest choice for me. I also got a 2nd cooler...a Hayden that measures 3/4" X 10" X 16". Will be going in front of the radiator and piggy-backing the B&M 24K. Should be putting on today if the shop opens after the monstrous storm we got (1/4" snow ).

 

I think I got the wrong hose for my B&M 24k.lol
I got the fuel injection clamp's, and the goodyear hose. But it's a fuel injection hose, will that work? It's got a blue interior.
The autozone here doesn't know what they're doing, my buddy that works there just said to go the back to check out what they have, can't complain only paid 2 buck's.

 

Wow, year old thread! This seems like it was ages ago.

 

Yeah it's an old thread but I used the mighty seach.
I got the goodyear hose but it's fuel injection hose, which one do I need?

 

You should be fine with that hose.

 

The goodyear fuel injection hose is more flexible than the one that came with the B&M kit, and has a blue interior coat in the hose. Kinda second thinking that it won't holdup to the heat of the trans oil, not sure.
What do you guys think, is the goodyear hose you guys using specfically for transmission oil/cooler????

Thanks

 

i went to napa and had them get the 4000PSI hydrolic hose and put 6AN ends on it....... Rossler put 6AN fitting on the tranny and i have a 6an cooler

works great so far

 

No kidding! I was worried that you were trying to smoke my trans!!!!! Good info in this thread none the less and for once the search works!

 

According to my gauge, my tranny hasn't seen above 180* since I installed it.....I didn't think it was possible to smoke one of your tranny's anyway!! It's still puts a smile on my face every time I drive it.

 

I have gates transmission cooler rubber hose from bumper to bumper..works great.

 

I've always used rubber trans cooler line, Gates or Goodyear. If you do go to Autozone or anywhere make sure they give you the right stuff. I recently ran a set and they tried selling me fuel line.
Last I heard it has to say Transmission Cooler line on it to be able to run at the track.
The Autozone stuff usually has a number, make sure it rings up as trans line when you go to the cashier. I also use worm type hose clamps that just fit, too big and they will leak.
I've connected hose straight to cut off hard line, compression fitting to hose barb, etc, usually with no leaks or weaping.

 

i'd like to know this as well

 

Zombie thread, sweet. How are you guys tranny staying so cool with just those 14k BTU coolers and such? I had a pair of 28ks and the thing wouldn't stay below 240*. I've since removed A/C and converted the condenser to a trans cooler and it hovers around 160* once warmed up, maybe 180 after multiple WOT runs. Oh btw, to keep it relevant I use the goodyear 5/16 with those little hose clamps and it works fine, no leaks.

 

I've never used a B&M but every one I've used came with 11/32" line.

 

how much stainless hose do you need to run to the cooler and back?

 

I''m going the push loc route on mine,no radiator cooler just the biggest B&M stacked
plate jobbie they make 29,200 gvw 11"x11"x1-1/2". The real push loc hose is lighter
than the rubber hose also.

 

What fittings are everyone using out of the trans on a 4l80e?You have to use the rear fitting that extends to the inside so do you use the factory quick connect lines or is there an after market fitting that will work to hook an type fittings to eliminate the quick clips?If so where do you get them?
