TCM tune seems to change or jump out of tune after a few days???

I have a 2010 Silverado 6.2L... 3.73 gears and stock size tire. I have a Circle D triple disk at 2600 stall. I had my truck tuned on a dyno in HP tuners format. Seemed to run fine out to about 4-6 months. Then I started getting unlock/lock at 1500 RPM.... Decided to buy HP Tuners software. Now when I load a tune, it seems to go out of tune after a few days. Get the TC working OK with no slipping or in/out jumping and after a few days, it starts. Engine and trans has about 130K miles. Right now, it's jumps in and out at various RPM's and speeds. Seems to be more frequent as torque goes up. I thought maybe a pressure issue, but the TC seems to lock in hard like a triple disk does after you increase pressure table. Bad TCM????

Anyone have this issue or have an idea what this may be?

Thanks

Even though you are reflashing and telling it what to do, the ecm still has self learning abilities that will change shift feel based on what it thinks it should be doing. No for the jumping in or out I would say something telling it to in tune, or the clutches are wearing causing the trans to try different pressures in an effort to keep it grabbing.

post your tune and someone could shed some insight into what it could be

Here is my tune file. I don't have a log yet. I'm a newbie and still learning.
