Are there any differences between the two? Can they be swapped between each other or what? Looking at an ls1 w/ messed up tranny and wondering if i find an lt1 4l60e can i swap it in. Also a 4l60e to 4l60e tranny swap should be relatively easy right? Thanks guys

 

Its possible to do anything but it is not a direct swap at all , You will be far better off to get the correct trans for your car.
