auto tranny problem

Once in a while if im cruising around 20 to 30 mph and let off the throttle a little bit then get back on it, its like it went into neutral and slams back into gear. Is this the converter unlocking? I was running the 210 tune and went to the 125 to see if there was a difference. Tranny still does it. Anyone else had this happen? should i put on my dpf and go to the dealer?

How many miles do you have on it? Check you tranny fluid for amount and quality (have enough? Is it light red or dark red?)

I only have 8700mi on the truck. Do you think it has something to do with the tunes? The fluid is where it should be and the right color.

I just experienced this for the first time yesterday, but while turning about about 15-20mph. I'm in the same boat too, color looks good and at the right level. Interested in what the problem is.
