GMC Sierra : Transmission Stuck in 2nd Gear - Code U0101 - Lost Communication with TCM 

Most underrated RU-vidr and hope things overturn soon.

He's too honest for some people so they under rate him....but u have my vote always. Best teacher

Watching from Kenya 🇰🇪🛠️

Always love these videos, a virtual teacher

Nice video and well explained and clear, directly to the point and show us all the process 👍 keep going bro👏👏👏👏

Supper Explanation you are the best

It's my first time to subscribe someone channel, Good verbal communication, I am french speaker and I understand your words and explanation. You 're doing very well your job

Thanks Deo! Very clear explanation and diagnosis.

Many GM Modules have COMM going in and COMM going out, this is a great system to use as you can bypass a module by shorting the input to the output and remove the module from the circuit but keep the overall circuit intact in an attempt to pull out a bad module to clean up the scope waveform. This job needs a different schematic to locate the actual other set of COMM pins. As for underrated, I have complained about repeated sentences, but the overall explanation of pin numbers, wire colors, and several other explanations given in your videos is going to put your channel ahead of the top diagnosticians since the new AI is going to pick up on your case study and catch more of what is needed to diagnose by an AI, most of the other channels will have to play catch up when it comes to fixing cars based on the Transcript of all the YT videos, this channel is ON TOP right now for sure in that Arena, cheers.

For me I learn about that very much 👍

Great explanation on the root cause of the problem, thank you.

Hello my friend, happy new year 🎉

Great job , as always 👍

Grasias

Hi, great content, perfectly done. Do you have a recommendation on where to buy a new or used TCM for the same truck model you worked on this video? 2006 Chevy Duramax 6.6L

Nice

Great video as always. What state are you in and do you provide training?

Good tutorial👍👍👍

Good video but why didn't the connector pin numbers match the drawing. Might have to be a good idea to use the electrical schematic to see what pins 26 and 27 are for or why they didnt match to the actual connector. Did the new TCM fix the trouble?

Deo, what is your procedure for testing module circuits? Did you have the bat neg lead lifted? I assume you had the positive bat lead connected. Any special reason for the light instead of a vom? Thanks

Solid video!!👌🏾

I subscribed to your channel I like your content

Great vid !!!!

Good stuff, but why no wire at position 26.

You never found the ground side of the second hi speed data lines

Good stuff..

Nice presentation. I'm puzzled at what happened to pin 26

I just bought a lanovo scanner i need yr support please how can i get u intounch 4 communication bro

Where can I get a light bulb tester like that one ?

30:05 the list is wrong, looks like the tan + white wire's right above in pin 6 instead of 26 👍
