09 Cummins w/68rfe is it tuneable?

[376FD]

Hello everyone, I've had hptuners for years now and tuned several LS based platforms and some of the gm v6 stuff but never tried a diesel. I just bought a '09 Ram 2500 with the 6.7 Cummins and a 68rfe trans. It's been deleted and tuned at some point by someone I can't find using an unknown tuner. I read this thread: https://forum.hptuners.com/showthrea...ummins-deletes!
So I don't want to even read the tune for fear of bricking my ecu. I'm okay with the power level... not really but it's okay for now, but I'd really like to make it shift better.

Can I tune just the trans with Hptuners or will this possibly cause ecu issues as well? Thanks in advance for any help/info.

It will be able to be tuned, not a problem. It has a separate TCM from the ECM, so just be sure to hit gather info button to exclude the ECM from the read.

Excellent. Thank you. I'm on a work trip now but I'll plug in and start playing when I get home.
