Had a circle d XL13 torque converter installed, went to the track, first pass was ok but every pass after was bad! It would shift from 3rd to 4th and hit a torque limiter. I figured I was at the limits of my factory trans so I pulled it and had it rebuilt. I shipped the torque converter back to have it refreshed. Got everything back. Long story short is it's still doing the same thing. Before it would only do it on the track but now it does it on the streets. I have logs and have had my tuner look at them. What it shows is the torque converter locking and unlocking when it's commanded to be locked. Any help would be great.

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.
