Launch SmartLink VCI (comes with X431 PAD V/PAD VII/PRO5) does work as a J2534 programming device with many manufacturers.
When replacing Chevy’s transmission if it is a six-speed or 8-speed or 10-speed, they have a module built into the transmission that has to be programmed.
Here we will show how to program Chevy transmission using Launch J2534 and Techline Connect.

The Launch Techline Connect.
Connect vehicle
Each time you open it it’s going to check for updates.
It doesn’t always successfully update so we’re waiting waiting waiting and we get a message for some updates.
Once update finished, wee’re going to connect to the vehicle.
It should pop up a screen to pick our j2534 communication device we are going to pick the Launch J2534.
You will see it connects with Launch J2534 interface
Select Replace and Reprogram
Many of these vehicles don’t allow used modules to be programmed so if you put a used transmission in you will likely fail programming it.
But some of them do go through just fine this one.
It’s a 2021 model. It is kind of hit or miss some of these vehicles will program the engine control module and the transmission control module in a sequential programming.
Select TCM module
Confirm the ECU has been replaced.
Downloading calibration from server
It’ll drop down fairly rapidly most of these vehicles take 3 to 7 minutes to program the transmission.
Program ECU until completed.
Then it should pop up with a calibration confirmation screen even though it’s at 100% it’s probably doing a little bit of file cleanup.
So here we go we have the VIN number TCM programming it shows that it was complete.
Clear fault code and test new TCU.
