The link I posted is for a 700 shifter shaft I believe but a 4l60 is basically a little longer.
Basically the procedure is unbolt the shifter lever and the prndl, be careful unplugging the prndl it's known to be glued in. Ordinarily i use a wrench for the bolt hidden behind the wire harness so that I don't have to unplug it. The tool screws in grabbing the seal and then you pop it out. you use the other piece as a way to push it in. Here's a link for an Astro van but it's still a 4l60e

try searching for 4L60e shifter shaft seal replacement and you may find a better tutorial.
