Downshift issues when moderately accelerating, no WOT.

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.

Downshift issues when moderately accelerating, no WOT.

Build is a 2014 Chevy SS procharger 416 with 6l90E GM reman. Triple disc ~3400 stall bolt together from TCI.

Experiencing two downshift issues when easing into moderate acceleration, no WOT.

1. Scan at time 3:08:30.049 to 3:08:32.457 is one downshift issue. Occurs when rolling thur toll plaza and moderately accelerating.

2.Scan at time 03:13:12.350 to 03:13:13.523 when at ~58mph and easing into pedal.

 

To note also fighting 1-2 shift at drag strip, hitting rev limit but makes the shift. AFR is way off at ~10.6 so MAF is off. Working with tuner but having no success with 1-2 shift.
