Here is a 2009 T42 4L80 calibration. It is stock other than the VIN being changed for a project. Maybe this might help.

Hmm that's a lot of stuff that's different. Wonder if I should change vin and flash it after fixing gearing

In that file the WOT MPH shift parameters are upside down (from the factory).
Which table?

The WOT shift MPH parameters:
D1011 vs D1061 (and others)
D2011 vs D2061 (and others)
D3011 vs D3061 (and others)
the downshift MPH has to be below the upshift MPH.
Is there a 2012 vehicle 4l80e calibration I can use in my t42?
