Default 4l60e transmission lines ?

i need to know which line on the transmission goes to which part of the radiator, awhile back my friend cut the lines when we pulled the transmission out instead of using the quick disconnects god only knows why,

so i have rubber line's to bridge the gap, but now its been so long i cant remember which line connects to the other
so if some 1 could tell me where the top line on the transmission goes to the top or bottom for the radiator would be awesome

The bottom port on your trans is line out. It goes to the top port of your radiator.

No, it doesn't. Bottom on the trans goes to the bottom on the radiator. The bottom of the radiator is the inlet. And yes I'm aware that doesn't make much sense and defies all logic.

Practically it really doesn't matter which way, because it goes thru the radiator in a single line. It is not spread out like in a container, like the radiator for coolant to the engine.

THe important thing is, that you, youself, know which one of the lines is output line, and return line, if you install a temp gauge, or an extra oilcooler...

If so, it should be like this: Trans >> temp gauge >> radiator cooler >> extra oilcooler >> back to trans...

Im confused about what you are confused about. The bottom on the trans goes to the bottom of the radiator and that is the trans output line. Can't get much clearer then that.

Default Simple Answer and Diagram

The top of the transmission is the INTAKE. The bottom line it the OUTLET.

Bottom Line(OUT)------>Temp Gauge------>Radiator----->
Extra Cooler---->Top line to transmission(IN).

Why not change your "diagram" so that the "Top line" is on top of the "Bottom line".


It might be easier to remember it as "BO" Bottom Out.
