As far as the TSB on 8 speeds, if under warranty and the problem shows up before 35,000 you are good for 30,000 more miles before it reshudders. It's a band aid repair. It's a common complaint on Camaro6 forum. GM has no 'fix', that's one reason they moved to a 10 speed transmission last year.
I have a 2014 Impala 2LTZ with the 6-speed and the transmission has performed flawlessly. The 2012 Impala LTZ (8th generation) that I previously had also had the 3.6L V-6 and the 6-speed and it also performed flawlessly.

I have not owned a GM vehicle with the 8-speed transmission, but have read a lot about the shudder complaints online - especially with the Corvettes and the GM trucks.

I’m amazed about the number of complaints - and the eventual TSB issuance and new fluid for the 8-speed transmission. You think GM would have detected the problem with their testing. I guess there is nothing better at detecting problems than “real world” testing by customers.

I have a 2009 that I bought in 2010 with 45K miles on it. I have never had a problem with it. Replaced the transmission filter and fluid at 100,000 miles, replaced the plugs and wires, and all of the filters (oil and cabin). I now have 156K on it and have never had a problem with it other than the factory recalls. Love the car.
