Quick Question- on the trans which is the in and out. I have read on here that the top is in and bottom is out. In my manual it's hard to make it out. Is line #1 on bottom and line#4 on top?
According to the A.I.M. drawings, the most forward fitting on the trans is the "Cooler Outlet" fitting which transfers to the upper connection on the radiator; the other fitting is the "Cooler Inlet" fitting which connects to the lower radiator fitting.
