Thread: Transmission Oil Leak at Radiator

Hello

I have a transmission oil leak where the line connects to the radiator. I'm not sure yet if it's the upper or lower.

I'm looking at rockauto and see the below pictures on parts. One is the radiator and one is the part thats on the radiator for the quick connect lines. Does anyone know if the bolt/o-ring picture i have below, is this stock on all of our radiators?

Thanks.

what i would do is look up the trans line, cause thats whats is most likely leaking. unless you played with it, then un hook it and push it back in, its held in by a clip

when the part on the rad leaks it leaks coolant. see the o ring on the back, thats what seals the coolant inside. it threads into the trans cooler in the rad.

I see what you're saying. I think what I'm going to do is replace it all. Both lines and the 2 connectors on the rad and the two connectors on the trans. I know what part i need for the connectors that thread into the radiator, however is it the same two connectors on the trans? I'm seeing conflicting info on parts websites.

old style is screw in like this, new is a push lock like the radiator.

When you refer to "old" style, are you talking about pre 2000's? Mine is a 06 and I'm pretty sure mine has quick connect.

Am i correct in thinking I'll need one of each of these for the transmission side of things? First is the short fitting and the second is the long fitting.

Mine was leaking and it was the orings on the fittings. I replaced them and the leaks stopped. That very well could be whats going on with yours.

based on how inexpensive it is to change the fittings, im going that route. Rather knows its done right and not have to spend more time on it. Not to mention I think two leaks may be the problem. So I'm planning on doing hoses too.
