6l80e with tap shift no BCM

yes. There are other settings that can override it and force an upshift or not allow a manual downshift though. I forget their labels, but you should see settings in the shift scheduling tab that relate to max RPM or vehicle speed allowed in the up/down shift parameters

Well ive got this working on the car. Its using the Lokar PRND 6L shifter. But as I mentioned, and also as I see others in this thread have experienced, once tutd mode is engaged its stuck there. No time out etc. The only way out of it is to shift to N and then back to D. Quite annoying.
I see corvettes have an "S" position on the shifter after D. Seems thats how they go into/outof sport mode (where TUTD is available).
Also, I think the wiring shown may be backwards, when we first got this running the "UP" caused a downshift and vise versa.

Any of you guys use a shift indicator that ties into the canbus like these?
