Where to get Transmission Cooling Lines

[MustangP51]

One of the cooling lines for the transmission rusted through and had a pinhole leak in it. I temporarily fixed it by cutting out about a 1 foot section of the line and replaced it with a length of 3/8 rubber fuel line and some hose clamps.

However I haven't been able to find the replacement lines anywhere. Does anyone know where to get them? or have the part numbers? I'm going to replace both.

Thanks

Stick with your solution -- the lines arent high pressure so that rubber hose should work fine.

 

[MustangP51]

I would but I'm worried the line might pinhole in more spots, they arnt in very good shape. Should just replace the entire run with rubber hose, or look at something like stainless steel braided lines? I'm worried about heat melting the hose. They run right above the exhaust.

Ford dealers can order all three steel transmission cooler lines as replacement parts - prebent and ready to install. I bought a set for my Explorer/Ranger 5.0L conversion last year. I don't remember the exact price but I do remember that they were not cheap.

how difficult was the install?

Bob, I had a set of the three ordered this Spring, and they didn't come. That was a different parts guy for me, my guy has been fighting cancer.

The rubber line may work temporarily, but expect to have a leak at sometime. Without the bulge at the end like the cooler line connections, rubber lines usually leak and/or blow off.

The stock lines are still available, but the long one from the trans to radiator may be too hard to install. You might make a new one to reach from the trans to the cooler area, with common steel fuel lines available at most parts stores. I have found at least a 60 or 70" length locally, they tell me. The ends match the trans fittings, and inverted flare fittings are available to join pieces. The two short length lines wouldn't bad hard to install. The radiator does have unique fittings made for the OEM lines.

Ill consider using steel fuel lines. Are you against using braided lines? I can get them fairly easy and cheap. I love you idea of installing an inline filter, I might consider doing that.

 

[CDW6212R]

I'll be using SS lines for the filter and coolers, and I know that others have made all of them out of SS. That's just very expensive and they would have to be supported in several places.

i heard that rubber fuel lines and rubber transmission lines are two different animals. I did an aux. transmission cooler and bought 3/8" fuel lines at first thinking it would be ok. Evidently the additives in transmission fluid will eventually degrade rubber fuel lines. IMO, you will be fine not needing the metal OEM lines and just going with 3/8" trans rubber hose and barbed NPT fittings

Bob, I had a set of the three ordered this Spring, and they aren't coming. I think that Ford obsoleted them since you got them. My lines look poor so I've planned to build new ones.

That could be. The dipstick for the 4R70W in the Ex 5.0 has been discontinued. I got one through a dealer search. :thumbdwn:

I suggest making new ones with common steel fuel lines available at most parts stores. I have found at least a 60 or 70" length locally, they tell me. The ends match the trans fittings, and inverted flare fittings are available to join pieces. I have four sections needed after installing a filter in the trans outlet line.

I am using a 99 Explorer engine/trans/radiator. The fittings on the OE Ford steel lines have about twice as many threads where they thread into the radiator heat exchanger. In my application, the fittings on the off-the-shelf lines at the local parts store were the correct thread but could not come close to sealing - their shorter length caused the hex to contact the rad fitting before the other end of the fitting could capture the tube flange in it.

how difficult was the install?

A bit of a struggle to route the two along side the engine. Had to reshape some of the bends temporarily along the way and then restore them after getting the lines into position. On the assembly line, I'm sure that the lines are put in place along the frame before the engine is dropped in.

i heard that rubber fuel lines and rubber transmission lines are two different animals.

This is true. Always use real trans cooler hose.

OK, according to the parts guy at the local Ford dealer here, all three pipes are still available. There are 30~50 of each at the Detroit parts depot and more at other warehouses around the country.

Here are the P/Ns and current list prices. All fit 1998~2001 Explorer 5.0L:

F87Z-7A030-VA $39.98
F87Z-7A031-UA $56.98
F87Z-7C410-VA $40.57

Thank you so much

Click on "parts catalog" and punch in those numbers. They are all about 20% cheaper there.

These guys discount those lines by almost 30% off of Ford list. Like any online Ford parts outlet, some of the savings from the dealer list price gets offset by the shipping cost.

Thanks again Bob, my real parts man just confirmed lines in stock in the Atlanta warehouse, from 5 to 12 each. The parts source in CA has the best prices, but $12.50 minimum shipping. They don't answer the phone very much.

After an exhausting search with a 1998 Ford Explorer Sport V6 SOHC Vin X 5R55E TYPE Transmission I finally found this site for transmision cooler lines that twisted while repairing. It was the lower outlet line on the transmission and ran to the top of the radiator. No Aux. Oil Cooler. Look under Explorer and Explorer Sport when browsing for parts. FordPartsGiant at http://www.fordpartsgiant.com/. Now, each delivery company charges an oversize charge due to the lines being awkward, ie., USPS, UPS, FedEx and etc.(The reason for the additional fee is due to the size and dimensions of the package(s): 4LBS, 49 X 5 X 28) via UPS. Two lines at $46.78 / Shipping $23.87 Hope this helps in the future.

I have the OEM 302 lines, three parts, which I may not use. I have not decided if I will use any of them, or go with hard fuel line to lead to coolers and filters.

The lines do take up a lot of space(big box to ship).
