Hey Seth, got a six month update for us? Was it worth it? Would you do anything different in hindsight?

Hello swathdiver!Hey Seth, got a six month update for us? Was it worth it? Would you do anything different in hindsight?
Nice work! I use Sonnax Zip and Surecure kits across a variety of transmissions including the 6L80/90 and they always work well.Hello swathdiver!
Update is: all is good in 6L80-land. I am very happy with the work I did. I have peace of mind in that the fluid is flushed and fresh, the ZIP kit has addressed several known wear issues, the pressure switches are rebuilt, and the BlackBear Tune had made it that much better.
I cut the remote hydraulic filter apart some time ago, and found absolutely ZERO metal or debris in it.
The transmission just does its job. It runs cool, shifts firm and quick, and is trouble free.
Thinking about it, I would have gotten the Tech 2 first, then done the work. That would have saved me the hassle and embarrassment of having to go to the transmission shop and not understand how long it would take.
Other than that, nope, I would not have done anything differently.
Now...this is my results, on my transmission. Mine only had 12*,*** miles on it, fluid looked OK, and unit shifted fine. Meaning I don't think it had any issues. I don't know how all this would work on a higher mileage unit that may or may not have issues.
Though, couldn't hurt.

@skpyle......I'm only halfway through page 3 and I felt like I should stop and tell you that I love you man!Ouch!

Let me know if you ever need to pull it down and open it up for an overhaul…Ill help out where I can.
I replaced this sleeve twice and it’s still leaking from the connector. I have a new TECHM installed as well. At this point I’m tired of dropping the pan to address the sleeve. Plus the pins aren’t loose.Soooo...back in post #34, I mentioned that there were O-rings I didn't use in the shift solenoid filter screen kit. Because I didn't know what they were for. Now I know. I was watching a youtube video from Precision Transmission on teardown of a 6L90E. Those O-rings are for the black plastic sleeve that the TECHM electrical plug interfaces with the external transmission wiring harness.

Note O-rings in the bag in the red circle.

Next time I drop the pan, I will replace the O-rings on this sleeve.
