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.

6l80 conversion hunts gears

I have a customers 46 chev sedan in which an LS2 & 6L80 have been fitted. at steady throttle it will drop to the next lower gear by its self then after about 5-10 seconds shift back up. for example at 80 kph it will shift 5-4-5-4-5-4 at 100 kph it shifts 6-5-6-5-6, it seems to take a while to acheive 6th also. the engine & trans are standard with standard tunes, I have recalibrated speedo but no real difference.

The ECM OS is 125010 & the TCM os is 24239353. I read elsewhere changing the TCM to OS 24243170 fixed it so I tried it but it got worse.
