Evening all! once again I apologize for the late reply. Just giving an update. I have clocked 1,111 miles on the new transmission. This evening I drained the pan to see what is going on and how things were looking. I am uploading 3 photos.
1. The transmission pan with just the fluid dumped but the pan not wiped. As you can see the pan is very clean minus the dark marks which is the grease from the magnet. The fluid came out very bright pink with no visible particles. After skimming the pan with a pen magnet (next photo) there is some peach fuzz going on which I expected. The third photo sort of got me on the edge of concerned but again I hope it's due to it being a new build and will clear up by the next fluid change. If you look at the filter's "edge" you will see a noticeable amount of tiny "glitter" particles that have rested on the edge and center. once gain since this is my first build I am not freaking out and hope this is expected until break-in? Also the filter element was not clogged.

Once again fluid is bright pink, no burning smell, still shifting like a champ with no odd behavior. I have to wait for reassembly as my ACDELCO filter had to be ordered. I should have it tomorrow.
If you installed new bushings then you should have some glitter from them wearing in to the shafts that pass thru them. And any new hard parts installed will wear in also. Its when the chunks showup is when you cringe.....and then order a new rebuild kit.

Yup, new bushings and hard parts were installed, I will be ordering an aftermarket pan soon, with some luck I will be in the clear next time I check my fluids. Thanks!

Good job man. Lot of reading there, did you do any sort of shift kit or just go back to stock separator plate and springs? I usually do the Transgo HD2 kit whrn i do a 4l60e.
I would stay far away from shift kits there absolutly junk they'll ruin your transmission in the long run.

I think you will find that the hd2 is the go to for any kind of life support for the 60e..
I have run hundreds of shift kits in all sorts of models from different brands with great results.

All I can say is wow. I briefly thought to try this but then I looked at the job and said no way. So amazed and impressed that you bit the bullet. Awesome job.

Who on earth told you that? They were lying to you or just didnt know what they were talking about. You do realize that many of the aftermarket shift kit makers supply transmission shops all across the world with parts that have been engineered to be even better than OEM parts and in many cases fix OEM original design flaws, right? These aftermarket manufacturers dump alot of money into R&D just to fix car and truck manufacturer engineering screwups. Its happens so often that there is alot of money to be made and those aftermarket manufacturers have seized a very profitable sector.
Famous screwups:
GM Sunshell center hub weld/ thin shunshell steel
GM TH700R4 front seal walks out
GM Valve Body valves premature wear and seizing
GM Narrow 2-4 band
GM 4 pinion planetary...shouldve always been 5 pinion from the beginning
GM Transfer Case pump rub
and the list goes on and thats just for GM....We would be here all day for Ford and Dodge.

If you watch the Precision Transmission channel on YouTube Richard goes over all this and much more as he takes apart various transmissions including the 4L60E.

Ive seen richards vids. He goes over all of "this"? What is this? Shift kits are for a specific performance level and will not yield good results if not paired with the right transmission that has certain parts already upgraded but their are also shift kits that work for OEM transmission builds too. Most of the time when a tranny doesnt work correctly after a shift kit is installed is because the ding **** that did it at home in his driveway, the same ding **** that has never opened up a tranny in his life until then...did it wrong. Or is trying to fix a problem that a shift kit wont fix because they dont know how to diagnose a tranny problem.
There are "richards" all over the U.S. Ive ran into quite a few of them....they are the ones that taught me how to build when I did it for a living. ;)

There are of course alot of ding dongs that work at or own a tranny shop too. Those are the ones you have to steer clear of.
