How do you find the return line on a transmission?
How do you find the return line on a transmission? Expert Reply: The surest way to find the return line in a transmission cooler system is simply to run the cold engine for about 15-seconds while it is in gear. Then immediately feel the two transmission lines.
What happens if you hook up transmission lines backwards?
If you had it reversed, the pump would be trying topush fluid through the bottom of the cooler, up through the cooler, out the top into the bottom of the rad, and up through the rad to the top. More weight to push.

How do I know if I have transmission cooler lines?
The surest way to find the return line in a transmission cooler system is simply to run the cold engine for about 15-seconds while it is in gear. Then immediately feel the two transmission lines.
Can you bypass transmission cooler?
When the transmission is cold, the thermal bypass will “bypass” the cooler so it can bring the transmission up to operating temperature more quickly. … The bypass works very well with other coolers, such as the Tru Cool™ 49211 cooler. So if you already have a cooler you like, adding the bypass on is definitely okay.
