I have a take-out 6.7L from a 2008.

I have the ECM (a CM2100A) but didn't get the TCM for the 68RFE.

I'm wondering if I can purchase an e-Bay TCM and plug that in and if a year-matched working TCM will work OK, or does it need to be matched to the ECM (I guess by a dealer)?

Or maybe there's a vendor I can provide my VIN to who can sell me a TCM that's programmed correctly.

I want to run this pretty much stand-alone as much as I can.

The engine/trans is out of a wreck, and I want to get it going in a swap.

RevMax seems to sell a TCM replacement / reprogrammed, but I don't know if buying one requires the VIN so that it's matched.

I could spring for the RevMax unit.

I'm unsure when I'll have funds to dive into the trans for a few $K of better parts since I'm on a slow-moving budget.

I could ask RevMax, but maybe someone here knows.

Thanks.
