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.

 

[RAMurphy]

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.

I was referring to items like you mentioned. In my 4L60E the shifts seem very soft but maybe that's the design. By soft I mean almost can't feel them. In my 95 Suburban you could definitely feel the shifts. Apparently it's okay because I'm at 170k. Here's a question - Does changing to a slightly firmer shift cause less wear to the clutches in the transmission?

 

[Mudsport96]

Firmer maybe. Quicker definitely.

I don't know why i never found this thread before.
well done sir!

I completed my 6l80 recently, so far I'm right around 1300 miles or so and all is going well.

I cut my teeth on an early 700r4 in my 84 vette.
By the time i was done, the only thing 84 about it was the case, input drum, output shaft, and valve body.
I used 5 pinion planets from a 4l65, and upgraded rear support to use the later wide sprag from a 4x4, and a bunch of other parts.
Pump was from a much later unit, I had to replace that due to a grenade'd no name pump rotor that came in the rebuild kit.
v2 of that transmission got all of the upgrades + a billet steel pump rotor.

I have an 85 C4. Did you leave the misfire injection in yours or yank it out?

The cfi is actually pretty simple, think of it like a motorcycle dual carb setup and it's easy.

So yes, still in there for now.
I'm at the limit of how much air they can pass, and they are about to get bored out to a larger diameter.

Sorry for the late update everyone. Crazy busy at work, rebuilt my computer and had a fun bout with Kidney stones (ouch!) Anyway. Transmission is doing fine! closing in on 3k miles (should have been there a while ago but with gas prices I have been alternating between the Tahoe and my little four banger for a bit.)
So far she still shifts like new! Nothing odd or weird going on. No chattering, burning fluids, vibrations. or heating issue, she just runs. Going to start a new thread in a bit on my next project. Hopefully I can get this done in a reasonable amount of time so I will keep everyone updated. I will make some update to my other posts from other projects that I done as well.

As always If anything happens I will let you all know!

Im lucky. Dont have to worry about it. The 85 models came with TPI.

TPI has it's on limitations, plus it's a pita to port that mofo!

 

[chevrol8t]

Just an update. Transmission still running strong. No other issues to report.
