Default 1995 4L60E RPO M30 transmission "output shaft sleeve" or "yoke tube" installation

I am new to this forum and i have a pertinent question about installing my new rebuild 4L60E M30 transmission in my 1995 Chevy-van 20

the question is my new transmission did NOT come with the "output shaft sleeve" or "yoke tube" with it the old one had it
i saw online that i would need a kent-moore J-21426 output seal installation tool to do so , after checking that shaft i notice that there is a smooth portion of the output shaft that is near the speed sensor reluctance wheel where i think the tube might be pressed on.

Now HOW Deep is that tube needs to be inserted to the output shaft and what diy tool can i use to do so.

I have checked in instruction documents including everywhere on the net but did not find any Specs about it and so far found Nothing aside of the K-M installation tool J-21426

Here's a pic of one the tube already pressed on the output shaft not from my transmission



here's the output shaft Without the sleeve




here's the bare sleeve with it's O-ring


the last pic is the K-M J-21426




here's the link to the K-M J-21426 tool bellow

BUT $219.00 is kind of pricy for a tool ill use only once

any reply appreciated

Steve

My research indicates that not all 4L60E's get the output shaft sleeve. It is model dependent. That's all I know for sure. Maybe transmissions mated to a transfer case don't get it.

For transmission that do have the sleeve, I think the sleeve rides the journal after the tone ring (the smooth machined section).
Instructions say "DO NOT position output shaft sleeve past machined surface of output shaft."

The statement "DO NOT position output shaft sleeve past machined surface of output shaft." is it coming from a GM service manual ?

Guys usually use a large socket or other solid round piece to install stuff like that.
