Oh, for the Buick Regal, the T76 is only used in the 2.4L, the 2.0L Turbo uses a F40-6 trans with an Aisin TCM :Throwup:, doubtful we will ever offer support for that.

I get an "Unrecognized PCM" message when I try to tune my T76 :( ???

Strange, I thought I'd mapped every T76 file we had sent in.

What was the fix...?

A file that was sent to T76 tuners who requested it. It goes into the Calibrations folder and opens the maps.

These transmissions do not like the ECM being tuned, I've found when the torque from the ECM is changed (because of tuning) the amount of torque reduction requested form the TCM is dreadful, stock TCM tuning I've seen -12 degrees final timing on a shift, and the shift drags out for at least 0.7 sec :shock:
In the end all it took was to drop the desired shift times way down, feels better that way too.
