4R70W Trans Cooler Lines

[71 CA Bronco]

Help a brotha out. I'm beating my head against the wall getting my tranny lines away from my exhaust (explorer swap, Sanderson Headers, 4R70w). My bender can't bend any closer to the flare, so I will be really close to the exhaust with the cooler lines.

How did you guys run your lines on the 4R70W to keep away from the exhaust on passenger side? I think I either need a real close bend (nearer the flare) on the tubing, or a good 90 swivel fitting. I tried the stock explorer lines and have the same issue. Any help on this is greatly appreciated.

I'm thinking something like this would work if the threads were right.

Get some good heat shielding on the hoses and make a small heat shield just to defect some of the heat looks like you have enough room

^^^ what I did with Factory manifolds... And I re used the factory Explorer lines as well.

Clean install you are doing there!

This works.

Thanks Guys! I appreciate the help. Lots of good ideas. I think I will go the route Viperwolf went with a heart shield. I get nervous around the exhaust and its a tight fit through the frame rail.

Mr. Wolf, any chance you have a part number for the adapters you used into the trans? ;D

From another thread:

You want the Fragola #481670-BL at the trans. Then you can run -6AN braided lines.

That's them.

Cool thanks. Any preference going with the steel ones vs aluminum? Any issues going into the alum housing of the tranny?

The adapters are aluminum. I used Aeroquip PTFE hose which requires their steel hose ends. Good for plumbing high pressure power steering lines also.

I slipped the tube inside a rubber hose to act as a heat shield/insulator.
