Anyone else get some paperwork for this? I'm just curious as to what it's for, if I can expect any differences etc. I've never had a complaint about the transmission so I'm a little curious about it. Dealer called it a recall however it's listed as a TSB, am I missing something?

i. Paddle shifting stops working until ignition is cycled. This can happen with a lot of
aggressive paddle shifting in low gears. The transmission calculates the clutches are
getting hot and will disables paddle shifting until key off event. The software has
been changed to bring back the paddle shifting function as soon as clutch
temperatures are reduced. The cluster will also provide a message to the driver that
informs them the paddle function is disabled.
ii. Vehicle will not stay in Sport mode. This happens whenever the vehicle is shifted out
of drive. The updated software keeps the vehicle in sport mode until the driver
deselects the sport mode or the ignition is cycled.
iii. Launch shudder. This condition happens when the vehicle is started and
immediately shifted in drive and 15% or more throttle is applied.
iv. 1 - 2 or 2 - 3 upshift bump in cold temperatures between -22° F (-30° C) and 50° F
v. 2 - 3 upshift bump. This condition occurs when the driver lifts their foot off the
accelerator pedal right before the transmission perform the 2 - 3 upshift.
vi. 3 - 2 downshift bump. This condition happens during light braking or coasting down
with no throttle input.
vii. 7 - 6 downshift bump. This condition happens during light braking or coasting down
with no throttle input
