"learned" shift?
I am having a problem with the 1-2 shift in my 4l60e equipped truck.
This is 2004 Silverado 5.3 with bolt ons only.
I had originally tuned for a bit more LP, no TQM, faster shift speeds, etc..
After installing a Transgo, the 1-2 shift became unbearable.
I returned all the settings to stock, except TQM, and all was well.
Until the next day, when the shifts became harsh again.
I have reflashed several times for other things, and each time the shifts are great for a day or 2, and then back to being too harsh.
And suggestions or questions?

Re: "learned" shift?
The faster shift speeds is where the learning is, the
"adaptation time". If you zeroed that then you want
to slowly bring it out to something more realistic (0
can never be achieved so max line will eventually result
from learning).
