Guys this is my first post and I have dug around to see if I could find an answer but still no luck. I've tried setting all the shift settings back to a factory tune, I've tried blue cat, I've tried shift points from an 05 Denali... still can't get it to lock up. I can command it to lockup and it does, but not on its own. Can yall take a look and see what looks off please? Should also note that I lowered the rev limiter in the attached file.
So problem 1 is no TCC lockup
Problem 2 is hitting the rev limiter on dowshift, however I rarely push it that hard anyway.
This is in an 84 Chevy k20 6.0 with a mild cam, 4L80E and NP205 TC.
