Default L92/LS3, e38, 4l80e…

Moving away from a vendor solution and into OEM for my 2009 L92 that I installed a LS3 intake, Camaro TB(6 pin), and EV6 injectors (fic) on.

I also run a 4l80e.

I have the E38 ECU from the ‘09 caddy in was pulled from.

Can/should I use the E38 with a T42 TCM? I’m not married to the E38 if there is a better OEM option for my combo.

I’ll be using HPT to tune, I have some reading to do on the HPT forum but I believe that I can use any T42 with an E38 and reflash the TCM to the calibration?

Get a 2009+T42 with OS 24243356. I got one from Auto 101. Of course you will need a wiring harness with the T42 plug and $l60 or 80 plug----not 6l80.

I have stacks of T42's. 05-14 are just different programming basically (its a slave module) they will run a 4l60, 4l65, 4l80 15 pin transmissions for the most part with different programming.
