Thread: Tranny cooler lines

  1. #1

    Thumbs up

    Hi guys,
    Hi guys,
    Does anyone know which lines are in and out for the tranny cooler lines on both the 4L60-E and the 4L80-E? The 4L60-E's are one on top of the other, and the 4L80-E there is one towards the front of the tranny and one towards the back. I would appreciate any help in this.

    All I can speak for is the 4l60e

    The bottom is the feed line, the top returns fluid to the tranny.

    My memory is saying they are the reverse of the 4l60E...

    Actually they are in different locations on the 4L80E....but i found out for the 80E that the front line is the feed and the rear line is the return line.
