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.

2016 silverado clunking into gear when skipping gears upshifting and downshifting

2016 silverado 6l80, circle D converter, stage 3 transmission rebuild kit

It will clunk into gear very intermittently and when watching what gear its in while I am logging its seems to be when it drops multiple gears accellerating or upshifts multiple gears when slowing down. it also seems to do it on the 1-2 shifts when slowly accellerating once in a while. Can't seem to figure out what tables in the tune file would cause this.

I've attached a tune file and log file.
