The TCM isn't locked on the 2016, your tuner should be able to easily access and tune without swapping.Just checking back in. After 6000 miles - still zero shudder. In my case, I think the latest fix is the real deal.
Still does some weird shifting once in a while but it’s unrelated.
Now I gotta figure out how to tune the tranny so it shifts like my ZF. Would love to mimic its torque delivery and shifts at part throttle...
Anybody ever replace the trans ECU in a 2016? I am going to have mine tuned soon.
Merry Christmas to everyone.
