I've got a 2006 Expedition, with the 5.4L and heavy duty towing package. The transmission cooler lines have rusted out. My mechanic is trying to replace them and is having problems. The connectors to both the transmission cooler and the radiator are so rusted that the connectors are breaking. He says that if he could get the fittings to connect to the bottom of the radiator and the cooler he could just replace those, but Ford doesn't sell them separately. Unless I can find these fitting I'm looking at a new transmission cooler and radiator. Does anyone know of an after market company that might sell these fittings? Any other suggestions?

PS: I'm no mechanic myself (I'd much rather work in a computer) so please type slowly!!

Thanks for any advice

 

You should be able to unscrew the other half of each fitting from the radiator and cooler. After they're out you can install any type of fitting you want.

 

Apparently Ford doesn't sell the fittings apart from the radiator / transmission cooler. Is there there some other company that makes fittings and/or lines that would work with the original radiator and cooler?

 

Are these fittings something common that I can find at an auto parts store? Or somewhere on-line?

 

Is this what I want??

Dorman Products - 800-753

 

It's hard for us to say without being there and seeing the existing fittings. There is no guarantee that the ones on the vehicle are OEM ones. You'd be much better off showing this to to your mechanic and asking him.

 

Sam, I making a number of assumptions, but if the CNY in your screen name indicates Central New York, as in the Syracuse area, I got my fittings for the trans lines on my '02 Navigator at the Lincoln dealer at Driver's Village, in North Syracuse.

I'm also assuming that the '06 Expy used the same part. Ford calls them 'connectors' under part# YL3Z 7D273 AA.

Hope that helps.........

 

Trans coolers aren't high tech, Theres nothing special about whats going on there. Theres TONS of different sized compression fitting that you can use as adapters. I've built these systems for trolleys and large box trucks. Any autoparts store carrys trans hoses (steel or rubber) and the compression fitting they work GREAT.

Good luck

 

The fittings you need are at....
Teckpak / Fitzall transmission parts and tools
Hope this helps

 

look at rockauto.com

Trans. code 4R75W; Connector Oil Cooler Tube; 1/4 In. Male - 1/2 In. Female
the parts are listed and you get a parts interchange list that tells you what other cars have the same parts on it.

 

I sure hope he had it resolved by now...
considering you've bumped an old thread lol

If not thanks to dalewilly at least other people with the same issue can now find the fitting they will need to fix the leak. In fact I think I'll send him some rep points for his post.

 

Anyone know the fittings on the transmission housing/case? I am getting ready to install an external filter kit and cooler, and would like to use a slightly larger line (braided SS) with JIC fittings that screw into the transmission housing.

Thank you,

I've had the same problem with my 05 F450. The line keepers collect road salt,debris, etc and cause the connector and line to rust out.
So far the only way to get those connectors is to buy a new radiator for big $$$$$ OR buy a trans filter kit from Ford part # FT 152. Ive seen the kits for around $80 on eBay and other parts sites. This part comes with 4 connectors, enough to fix your truck and a friends. Or just sell the connectors on eBay and make your money back.
