I was looking in the tcm file and I was wondering what the shift timing was about?
Keep in mind that I'm not an Allison calibration engineer, and would love to defer to one if they had insight to share. The way I understand it is that there's a target timing for the shift to take place or complete. The trim valves will adjust the on-coming off-going pressures to try to get the shift done in this targeted time. Lowering the shift timing should make the shift happen more quickly, and raising the shift timing should have the opposite effect. You can log shift time to confirm.

Nick thank you very much for the explanation. I have really enjoyed the training y’all have done.
