so im sitting thinking about how i wanna get rid of the 4l60e tranny in my truck for 4l80e, but i dont have the money right now for it. then i remembered i bought a 6.0 with a 4l80e attached to it. got them both for 2,000 from a cop buddy who had to sell parts from a chop shop they busted. i would use the 6.0 in my truck but it's from a 05 and my trucks an 07 . but at least i got the tranny,man im dumb for forgetting i bought that.
