Could not lock 4th on the rollers

[Madspeed]

We couldnt lock it in 4th on the dyno it would shift anyways Why?
Hi tthe green button selected the LB7 LLy tcm clicked 4th and also the checkbox as well as same for TCC then activate and it would still shift.
even started logging with the red button at the bottom. What gives?

Were you running the SC Tcm or did you change it? The SC TCM would not be controlled by that one.
