I am attempting to install an aftermarket transmission oil cooler in my 00 Durango with a 4.7L. Can someone please tell me which is the return line for the oil from the radiator to the tranny?

 

Crank it over and have someone stand there to see which one it flies out and thats your pressure line.......LOL

Pressure should be the front most line to the engine side on the trans.

 

i have an 03 dakota i am tring to install a trans line and that answer isn't really helping me. is it the top of the radiator line of the bottom radiator line? i don't want to see which one shoots out fluid either.

 

First of all I won't hurt if you just crank it over like three or four cylinders. I'n not saying run it!


Cold output from the radiator to the transmission cooler should be the one on the top passenger side of the radiator. The lower one should be the hot incoming from the trany.

 

i ended up doing this actually. i had no other way to figure it out and i hadn't gotten a definite answer before i was to that point. and yes it is the top line

 

Sorry, I was off for a few days.


Anyway glad to see you got it and you had 50% shot of getting it right.......LOL

 

Dang i missed this post all together, sorry I did not chime in I could of helped ya out. Glad you got it though, Welcome to the forums and sorry you did not get the help u was asking. sometimes we get a little busy and can't get to everyone, but we do try our best. Again welcome to the forums and hope to see ya back.

 

ohh it is not a problem. i am pretty handy on my own. i was just hoping to get lucky and find the answer so to not make a mess. i was getting ready to tow a heavy load home from the woods and i wanted to make sure i had a little extra help.
i have an 2003 4.7 4x4 quad cab slt. and i was pulling a fullsized f150 single cab 302 4x4 and a 2400lb trailer. yes this is over or right at the towing limit for the truck and that is why i felt a trans cooler could be a good thing to install. hehe

 

Well at least you installed the trans cooler.
