Restore your stock tune, update your Trinity, and you'll have the option to tune the TCM for a firm or hard shift tune.
This applies to all C7 Corvettes, as well as 15-16 Trucks and SUV models that are equipped with the 8 speed.

If the TCM is not up to date from GM, the tool will read out the existing file and ask you to send it to us, so we can add support for it in a new update.

Thanks

Will trinity works for Corvette C7 2017?

2017 is not yet supported.. coming soon though...

Any update on a timeline for the 17 models?

the 17 8 speed tcm is locked down, and can't be tuned unfortunately.

Hey Mike,

any update/tune coming for 2016 CTSv with 8-speed?

Thanks!
