20074 Tahoe 4l80e swap question
I've been reading conflicting info, so hoping I can get a straight answer here. Doing an 80e swap ona n '07 Tahoe with a Magnussen supercharged 5.3. Can I use the stock TCM with a reflash for the correct trans file? Or do I need a TCM directly from an 80e truck/van?

The t42 can be programmed to run the 4l80.

I see that now, there's a file for an '08 Express Van in the tune repository, and I found instructions for programming only the trans. Thanks!
