How about a picture?

Or check out this thread:

#5 is a picture of a 6l80, #9 of a 4l80e.

The trans is a 6L80. The cooler fittings for the 4L80 would be on the passenger side and they wouldn't be together as they are on the 6L80. Also, the 4L80 bell housing does not detach.

Duh, I'm not good with "right and left" and not everyone references from the back of the car. "Passenger side" removes any ambiguity. Thanks.
