Shift point change fro 6L90

How do you change the shift point with E38 and T43 (6L90)? I want to raise the shift point.

Open up the TCM and edit the Part throttle shift tables...you have to read the ECM and TCM separately.

I'm not wanting to adjust part throttle, just WOT. I'll look at that table, though.

Post your TCM tune up.

Trans Calibration->Shift Control->WOT Shift Speeds and/or WOT Shift RPM. All the WOT stuff is there.
