My shudder was still present after the 1st round of flushing at 35k miles. Getting the car back it was better in some instances, worse in many. 200 miles later, the dealer had me bring it back in and was ready to tear down to replace the TC, etc and was denied by GM, who instructed the techs to repeat NA-16-175 again.

Although, the shudder is not happening at this time, it was inferred that a follow-up service item could be the next time they work on the transmission, as it shouldn't be that long before I'm back.

This makes 7 service visits for the transmission for the shudder and hard shifting that feels like the back of the car got hit when going 5 miles an hour. Flushing and resetting the transmissions 'smart learning' are bandaids on a piss-poor design.

Thanks,
Thomas
