trans cooler question

[turborich]

Which transmission line going to the raditator is the return line to the transmission? the top or bottom?

Thanks.

Hot fluid enters the radiator/heat-exchanger through the bottom and comes out the top to flow back to the transmission.

Thanks, I just wanted to make certain that I was going to use the correct line.

Thanks, Rich

So I take it that this article is incorrect? It says to use the lower transmission fitting. I just now found it.

I think the Tech article is correct.

OK , let me ask this. Who here has actually took there transmission line off to see which way the fluid flows on a Mark VIII? I just wanna make sure that I get it correct. I tried feeling the temps of the lines but couldn't really tell.

Ok... I got it installed and found a great site that has some good info on transmissions. http://www.txchange.com/main.htm Yes the top line is indeed the return line! Thanks to those of you who pointed that out.

The link I posted earlier was for a mark VII DUH! I didn't read it very well, I guess that's why it had reversed instructions. Well, one less thing that I have to worry about in the soon to be 110-115 degree weather! And that's in the shade!!!

I put a trans cooler in last week. I have a 94 and the top line is the out flow. If you want to check for sure just remove the top line and have someone start the car for a second or 2 while you watch. Be ready it flows FAST! A jar would be a good thing to have.

Thanks! Yep, its the top one. My cooler came off of an older mercury full size car. It was a engine oil cooler but I figured that it would work nicely for a trans cooler as well. I have been meaning to due it for a while but was just too lazy. With the heat here I figured that I better get it done.
