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?
