Credits needed and Which section to read up on (Mix matched Gen)

[tectactical]

I have a late 2019 Gen V 5.3, L82 out of a Silverado Trail Boss, now 6L80 2wd.

I now have a wiring harness for the engine and a E92 ECM/PCM not the E90

How many credits will I need for the Direct injection 5.3 running off a E92 6L802wd?

Do I still refer to the Gen V section for posts and info?

Thanks

Depends, what year E92 did you buy?

The 2014-2016 E92's are only 2 credits. If it's a 2017+ E92, those calibrations cost 4 credits.

I'll look into it. I know it it's also going to control the TCM for the 6L80

Just remember that the PCM and TCM calibration need to be matching. So whatever combo this ends up being it will require that the PCM/TCM is flashed with the same VIN/Calibration so that they talk to each other correctly.

And only a GM tool can do that. HP Tuners can not do that flash, it can only be used once the files are on the computer.

So if I change the transmission in my street rod, i need to take it to the dealer or someone with a GM tool?

Its really not a yes or no answer. I would recommend reading the ecm/tcm if you ever hypothetically change the transmission in your street rod, ultimately that will determine the next steps.
