2014 Transmission cooler lines

[lpramirez]

So one of my trans cooler lines are leaking  but the replacement part they have at the store looks different that the one I have in my truck, the one I have looks like the acdelco 23370657(no were to be found), and the one they have is the acdelco 25999418, are they interchangeable?  Anyone with the same problem?

I found your p/n 23370657 on gmpartsnow.com @ $81.90

Also found it on Amazon.

Hope this helps

It's my understanding that the 657 p/n has the old thermal control valve that doesn't open until 194 deg. You need to get the one stamped "70" which is the newer revised control valve that opens at 158 deg.
