Yeah, si i want yo bypass the radiator lines from teh tranny, can i jut hook up a oil coller straight to the tranny and not use the radiator, and if so, which lines are in and which lines arou out, on the tranny....

 

On a 700R4, the top line is the return line (the top one on the radiator) and the bottom line is the feed line)... Doesn't really matter if you are going to bypass the radiator cooler. If you were going to keep the radiator cooler, you'd want to have the bottom line from the trans go to the radiator (to help heat the fluid up in cold weather, etc), then the top line from the radiator go to the auxilliary cooler input, then from the cooler output to the top line back to the transmission (so it can cool it down best right before it sends it back to the transmission)... Hope that was coherent enough..

 

Mist transmission cooler manufacturers recommend keeping the factory in radiator cooler and plumbing yours in after it. -John

 

is it really necessary or what....
