If you have a one-piece case transmission and you’d like to confirm that It is a 4L60E you’ll need to look at the code on the transmission. At that point you can be certain that you have identified a 4L60E.

In order to verify that you aren’t looking at a 700r4 you’ll need to verify that the transmission has a harness connection, and not a TV Cable. If the transmission that you are looking at has a one-piece case, you’ll want to make sure that you don’t have a 700R4/4L60.

Although, everyone would agree that the transmission got better as time went on. 60 is supposed to be for 600 pound feet of torque that this transmission can handle. The 4 stands for 4 speed, L is for Longitudinal (for a rear wheel drive vehicle), and 60 is the torque capacity. GM changed its naming nomenclature into a universal standard across all of its product line. The 4L60 is the latter model 700R4 transmission, only the name changed, if you think you may have a 700R4 look here to identify it. The one-piece case 4L60E was produced from 1993 through 1997.
