1999 transmission leak

I had the trans flushed,[on a 1999] they take the trans line off at the trany to do the flush. They said one of the connections was full of mud and they had trouble getting it off and it cracked. The said the replaced it.Now it is leaking around one of the lines. I went to ford to get new inserts or seal what ever they are called, they said I will need a special tool to get them out and to replace them. I did a search to try to find what I am looking for but found nothing on this.

Do i need a certian tool? And is this a commom problem? Does any one have a good picture.

Iam not the best at describing things, let me know if I can tell you anything else that would help.

If this is the connector that the shop that did the fluid exchange worked with....I would go back and have them repair it.

The type of tool used is a fuel line disconnect tool.
They sell them at auto part stores as a set of various sizes.....for someplace around $10.
They are nylon / plastic.....has a sleeve that slides up inside the connector to push the tabs back to release the connector.
You place the correct size (most likely 5/16") tool that fits slightly snugly over the smooth metal line......align so that it will slide up inside the fitting that the smooth metal line goes into.....and push the tool up inside the fitting....it should "click" when it is all the way in.
Then.....pressing the tool into the fitting firmly......pull outward on the metal line to remove the line from the fitting.

It is important to clean the connector of all dirt, as the dirt may cause leakage.

The instructions that I read say that sometimes one cannot get the plastic tool onto the fitting due to location and other things in the way.
In this case, the fitting must be unscrewed from the transmission case.
This may damage the internal ring and cause leakage.
Then the fitting must be replaced with an "angle flared" fitting.
In short, they have you cut about 4" off the end of the damaged steel tube, install a new fitting ( P/N 7D273) into the transaxle case, then use a small piece of 5/16" steel tubing, and install a flare nut on the end.......install in the new fitting. Clean both ends of the steel tubing....new, and the old.....and use a 5/16" length of fuel line hose to connect the old, clean end of the steel tubing to the short length that you just installed into the new fitting....and secure the fuel line hose with hose clamps.

Again, if the fitting that the shop used to do the fluid exchange is the one leaking.....I would expect them to fix it for you, as it is their responsibility.

This is an example of why I don't feel comfortable with messing around with those fittings.....as the plastic retaining part can become old.....worn out, and break after repeated use.
I prefer to disconnect the flexible hose from the steel line and do the job that way.
A section of fuel line and hose clamps are easier to replace....even though 1 end of each of the hoses did have a "permanent" clamp that I had to cut off with a small hack saw.....and replace with a hose clamp.

Thanks for the help. I took it back to the shop that flushed it. But the leak wouldn't show up while I had it there. It had never leaked a drop before, so I guess Ill try to fix it myself.

Would there be more pressure while driving? It was down 2 qts in 5000 miles, I hadn't checked it till I changed motor oil and saw all the transmisson oil all over the bottom of the van. I had them fill it and then drove it 500miles and it was still up. So its not a huge leak but still I need to fix it. Thanks again for the help
