you need to flash the computer to a manual. i think smarty is able to help with that.

I know you gotta tune it for everything to work right , but don’t think I saw anyone try and run it before the tune lol

The ECM wants to see the transmission, no transmission no engine run.
And he doesn't speak about tuning, you need to programm the ECM for the manual trans.

Dang, wish I would have been able to see that you were doing this, I would have been happy to swap you everything needed lol.

ive got the g56 in my truck so we could have swapped everything. Not sure why it wouldn't have worked other than mine being a 2wd so the trans would mount differently in my truck lol.
