EVERY table even TUTD set to 137mph for the 4-5 shift command and RPM at 6600 rpm but it shows 4-5 command at 121mph and does the actual shift at 6300rpm (see timing retard at shift event, PCS pressure changes) Usually I have no problems setting mph a little earlier than desired shift so it knows when its coming and then it shifts pretty close to requested RPM but not this time
This car (2015 Chevy SS) has been doing some wierd stuff, the TCS button doesnt seem to function at all I had to pull fuses to disable the traction control to make dyno pulls
Also the trans I THINK came out of a Caprice, TCM was flashed at dealer with SS operating system and they were supposedly matching OS numbers
