6R80 6F55 - Over-revving / commanded shift points??
Anyone else with a 6R80 or 6F55 from a 2015-up notice that the WOT tables don't really do anything? For example, in the two WOT tables, I have the 1-2 and 2-3 set for 6250 RPM. I adjust the Base / Sport shift schedules so the OSS at WOT pedals corresponds to the right engine RPM. However, during actual WOT shifting, it either bangs against the revlimiter or hangs at around 6500+ RPM. So I dropped the OSS for 1-2 and 2-3 down to values that correspond to about 5900 RPM and the 1-2 is now much better but the 2-3 still hangs at 6500 RPM. My first guess is that the 1-2 and 2-3 rev up higher than expected due to not having the TC locked up causing it to spin up too fast for the commanded shift point? I first noticed this awhile ago when I used the factory settings for this N/A 3.5 engine (6750 RPM commanded, 7100 RPM stock revlimiter) and saw the WOT 1-2 and 2-3 consistently bang against the 7100 RPM limiter and hang for about 1 second. Keep in mind this is straight from the factory.
