The fitting is replaceable if you have a flaring kit, because you have to cut the line to replace it. Before you do make sure it is leaking between the line and the fitting. Remove the line from the transmission, dry it off, and wrap the fitting with a layer of thread tape.Reinstall the line being careful not to crossthread the fitting. Push the line all the way into its place and start the fitting by hand.Watch your repair for a while to see exactly where it is leaking, if it still leaks. It would probably be easier to change the line than the fitting.Steel brake line does the trick and usually has the right fittings. If they have to be changed it is a lot easier on a bench than on your back under a car.

SOURCE: Transmission coolant line leaking on the transmission side.

Is the line before and after the connector steel? If you can cut the leaking section out w/ a hack saw, u can slip a section of gas line over the trans cooling line, and put a clamp on both ends, quick cheap fix that will last a long time.

SOURCE: antifreeze coolant leak at "y"

You can't purchase the "y" fitting seperately (only Dodge knows why), but the premolded aluminum hoses (or tubes) that are attached to it come right off and the "y" fitting alone can be replaced for a much lower cost in labor (like 1.5 hrs instread of 3 hrs labor). We just had it done on our 2008 Caravan, and the service department was very familiar with the issue.We paid $94 for the part and $120 for the 1.5 hrs labor. This is yet another problem with some not made right on the 2008 caravan.

I have a coolant leak around the transmission line fitting on the top radiator fitting on an 95 Ford f150 with a 6 cylinder. Can this fitting be replace by myself.


Yes, this is a pretty easy fix. You can replace the fitting but I would buy the replacement line and put that in. the fittings will already be on it and bent to fit. If you are leaking at the fitting there are probably several other points along the line that are ready to pop.

I have a 93 explorer and the tranny or oil is leaking really bad I think it's the tranny because it only leaks when in gear and its a bad leak it makes a line when I back up and take off or just sit s


Those A5 trannies are junk and can set the vehicle on fire in less than 5 minutes with low fluid. Red fluid is tranny, oil is oil. Rear seal-oil- big repair. Tranny coolant pipes-Tranny fluid-small repair. Replace filter, fluid, and gasket-it's probably over due-and check again for leaks. rear tranny seal leak, average size job.. Never use the stop leak! Throwing flour on the tranny works better-Just kidding.

Transmission leak spraying bad under motor on 2000 crycler concord LX 3.8


transmission line is loose @ connection, or has a hole(leak) in the line, even a crack in housing. trans is a large pump, high pressure, if you have a leak, just start your car and look under it, you'll know real quik.

New tranny in my 92 ssei now it has tranny fluid in the rad ???????


The transmission and engine are there own entities. Unfortuantly the radiator in some vehicles cool the tranny fluid. Its possable when the coolant lines were disconnected from the transmission or from the radiator, the seal was broken on the radiator where the line goes in from the radiator, so you wont see it because its internal. This will allow trans fluid to enter into the radiator. Be careful with trans fluid mixed with the coolant may cause engine damage. Your solution to the problem if this is infact the source would mean replacing the radiator, if you do this be sure to flush the coolant system to rid trans fluid.

If there is another dealer nearby get a second opinion. Repairs these days are very expensive.

My 1997 ford explorer overheated and the transmission slipped


Tranny fluid may have been contaminated with coolant since tranny cooler lines go to radiator or condensor.
I would fix your leak on radiator, then completely drain tranny fluid and filter and replace.
