Just got my 6 speed rebuilt due to thinking it was starting to slip. did a Standard rebuild with a sonnax 456 hd kit. The truck has a 408 stroker with a stage 3 cam with a LSA blower, and a circle d triple disk 2800 converter. I used blue cat to set up everything and it feels just fine, the only issue im having is the shift from 5 into 6 at moderate to heavy throttle. It slips. Not sure why, and I have a feeling it has something to do with torque management. The timing pegs at -7-8 ish. Other than this issue, i have it shifting super proper. Just need to figure this out. Moderate acceleration into 6th slips...I rebuilt it a month ago thinking it was the trans but now i'm not so sure, the trans guy also said it was the nicelt 6l80e hes taken apart, meaining we didnt really find anything. Can you please take a look Wacker?

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.
