This is from 1 yr ago:

Slip? Anyone who's "slipped a clutch" knows too much slip wears the clutch disc.

The TCM algorithms are "slipping" the TC lock-up clutch too much, wearing

the friction material, contaminating the fluid, and clogging the filter.

If you are a proactive owner, you take the vehicle for service before too long.

This scenario allows them to flush out the debris, change the filter, and see if there's enough TC lock-up clutch left to work.

The flush must remove clutch plate debris from all circuits and solenoids, etc.

New TCM algorithms uploaded

Some owners don't worry about it, or get told by service "not able to duplicate", etc.

In this further-worn scenario, the clutch in the TC is all but shot. Chances of debris clogging circuits and solenoids is high.

New TC at the least, and maybe new tranny too.

REPEAT - over and over

I'd heard GM is on the 3rd design of the converter. Maybe the newer ones have more material, and will be less likely to have problems when combined with the new fluid. Is this the first transmission GM's used that has the ECCC technology? If so, there's the problem. It seems adopters of new technology in cars seem to get burned until it's improved. Apparently, the 10 speed auto has a better TC, software, and controller. All the 8-speed problems in the C7 are what has steered me away from it since the 10 speed won't fit in the car.
