My truck did something weird when shifting from 2nd to 3rd it shook the whole truck when shifting, Is this a sign of troubles to follow?

I will make one calibration change for an additional $100 per change. For example, changing a shift point for a given gear is $100 vs changing a shift point and a pressure setting would be $200. That value can be used towards the full custom tuning price.
