Fitting size on transmission?
 

Well I'm trying to remove my cooler lines from my trans.
They are rusted on pretty good. I have the lines one goes from the tranny to the radiator and the other goes to the aux cooler.
I have the new lines but the old ones wont come out. I was just wondering if anyone new what the thread was on the adapter fitting that mounts into the tranny.
The steel line i'm replacing appears to be a double flare.
I just like to have all my parts in hand before I break the old ones off.
47RE trans

PB Blaster is your friend. Drown the fittings a couple times over a couple days before you actually try and take them apart. For some, you need the 'special tool' for the couplers.

Yeah been soaking them with aerokroil for 4 days now. the whole fitting is turning out. which means the tube is rusted into the fitting. I just would like to have all parts on hand so My truck isn't taking up the entire garage, while I wait for a replacement.
I have the ac line disconnects for the other end already

The fitting that goes in the trans is a pipe fitting if i recall. Not sure what size. I had the same issue with a spare motor/trans i bought. Had to cut the rubber part of the hose to remove the fitting out of the trans.

well here the elusive fittings. $40 a piece too. I about had a heart attack. Oh well. Posting here so someone else can find them. These are only for the 47RE though.

I bet lowes has 'em for 40 cents a piece......

Just so no one makes any mistakes here you can't just run down to Lowes to get the correct fitting. The fitting from Mopar is a tapered fitting and if you try to use a regular fitting from Lowes, Home Depot or other places it can break the transmission housing.

Don't ask me how I know!!!!! It was costly............................................ .............

You owe some people $$ :icon_slap2: :icon_no:

Pipe thread, are they not? No, you can't run 'em in tight. Just snug. :)

They are npt. Mine snapped off when I tried to remove it so I extracted it and got a new fitting at the hardware store. Mine is different though.
