2005 TTVA motor not working
I should start by warning everyone I am brand new to tuning but do have experience building 46,47,48 transmissions and cummins engines. I have a 2005 that has smarty tuning on it currently and I just built the trans and would like to play around with tuning the trans to begin with. When I log with the smarty I can see the TTVA motor moving as it should and everything works well but when I write the tune attached below to the truck I end up with the TTVA never reading while driving and logging and the transmission does not want to shift out of 1st until almost 2500 rpm. It does eventually shift all the way to OD and locks but its definitely not shifting how it should and is somewhat random. I am definitely suspect of the TTVA motor being the issue but not sure if there is another setting somewhere else that is disabling it or having an effect; or if possibly there is something wrong on the hp software side of things.
