Jim F. has a little shameless behaviour in the past
Thumbs down

Taurus has developed a transmission fluid leak @ cooler line fitting right at transmission. This is the upper fitting is this a common occurrence?

Could I possibly get away with cutting the factory cooler line and splicing in a hose using a barb fitting at the transmission? If so what thread size is the cooler port on the transmission? Thanks in advance...

Jim

I replaced both my steel factory lines with 3/8" hose. You need a 1/4" male pipe thread by 3/8" hose barb to replace the quick disconnect fittings in the tranny. Then you can then run the hose straight out and snake them under the upper radiator hose to get to the front by the cooler.

You will increase the flow through the cooling loop quite a bit by doing this. A good mod to do just for the cooling benefit.

Top one is red and hot, bottom one has blue tape on it (that you can't see in that pic) and is cold. But it really doesn't make any difference if you are just plumbing in a cooler.

I bought a replacement for the factory "quick disconnect" at Napa.

The manual does not say to screw fitting into trans first or to put line on fitting first. I have tried BOTH ways. Each leaks.

Must I use the method of ditching the factory fitting?
Is there some trick to getting a new factory fitting to work?

Please Help!

Thanks

Screw into trans first, then connect line.

I had to apply a little bit of 'threadlock' to keep my fittings from leaking....Mine only leaked when the fluid heated up...I was able to notice it coming right from where the fitting screwed into the transmission. Hasn't leaked since I put the threadlock on.

Teflon tape or pipe dope works as well - I used Teflon tape IIRC.

The replacement fitting already has thread sealant/lock applied to it when you get it from Ford. Do not overtighten the fitting or install and remove, unless you replace the sealant.

I have found that new fittings can leak from the quick disconnect (same plae it was leaking from, and the reason why you replaced the old fitting) you don't clean the hose end, then fuly insert the hose end, and lastly pull on the hose after you lock it in. There is some play in the quick disconnect and they don't seal properly, unless you pull on the hose to seat it against the sealing surface inside of the connector.
