I some how stripped out the upper trans line on my 3 row aluminum aftermarket radiator and am having a hard time trying to get someone to repair it. What would y'all recommend for a external transmission cooler?

Jeez.. You just need to drill and tap that damaged bung for a larger pipe threaded or a straight theaded fitting that will then hook up to the cooler line. This is no big deal. The most concerning thing would be to make sure the metal chips from the drill/tap work get captured so they don't circulate with the tranny oil. That might mean that you disconnect BOTH fittings and flush out the exchanger after the machining work. Again, not a big deal....

It's not an easy " drill and tap ". if you look inside the bung you will see a beveled edge that the transmission line has to sit against, sort of like a brake line. You could find a machine shop to take it to, have them remove the damaged bung and install a new one. but if you are going to add an external trans cooler, it needs to be good size, because it will be doing all of the cooling. You can get a heavy duty one and some of them even come with their own fan. Got's to check the sizes though. The money you spend on one, you almost could buy a new radiator or ship your back to the company for them to repair.

If you can't figure out how to correct a stripped thread problem, you probably shouldn't be working on it.

Gotta love this forum how they always have something negative to say! Thanks scrappy for being the only logical one! ����

Mr D.

You will need a new radiator, the lines are flaired for a reason. You might try using a bottom tap but it will be tough fixing this if the threads are really bad.

Yea that's what I was figuring. Thanks me d.

Take the Radiator out, get a new bung and take it to a welding shop. Here in Central Texas would cost $15.00 to weld the bung on.

Just had 2 bungs welded on my water pump 3 weeks ago.. Its a simple fix as you see I went with AN fittings but you can find bungs in all types.

Good Luck

lol I've been trying radiator shops and so far no luck. Didn't think of a welding shop! Where did you get a new bung at?

I got them on Ebay, just search for bung with the size you are looking for. On my Water Pump I used AN -10

If you were not so far from C Texas I would tell you to bring it down.

I had a issue with my Radiator, I took it to the rad shop and the kid said he could not find a new lower outlet. .

I found one in a few min's (ebay) ordered it and tool it to a welding shop.. Radiator fixed..

Good Radiator shops are a thing of the past...

Just go to Jegs or E bay and get an external one.

Seems like you could tap a pipe thread in the fitting. Then use a pipe thread to flare fitting. Make sure you flush out the metal filings. Easy to cross thread them and damage the threads. Make sure you use the proper drill to tap size. Fitting like this, not sure if you need a male or female fitting.
