At the very time when +General Motors and +Tadge Juechter introduced the 8-speed 8l90 slush box, praising its alleged ability to outshift Porsche DTC transmission, this blog condemned the newest slush box as a certifiable piece of shit, guaranteed to cause nightmares to anyone stupid enough not only to buy the latest generation of Corvette but also chose one with automatic transmission.

Now, in the fourth year of offering the 8-speed piece of shit auto, so predictably, +General Motors has nothing to offer to the owners of the cars equipped in a form of actual remedy but instead feeds the audience with the lure of a MAGIC TRANSMISSION FLUSH that supposedly will make the demons of transmission and torque converter failure go away.

So how bad are these transmission problems?  So bad that instead of one service bulletin the already infamous transmission has TWO service bulletins running concurrently.  While the first bulletin covers cars produced between 2015-2016, the second bulletin is the disturbing one as it extends its applicability to 2017 model year, along with widening the velocity range where the problems exhibit themselves so painfully.

In spite of the nightmares of dealing with incompetent dealers, waiting weeks and months to get their cars fixed, there are of course several unexpected benefits to the the tormented owners: for one thing, since the AFM inspired torque converter failures happen early on, the "lucky" owners get a temporary reprieve from the complete transmission failures which will reward the long term owners of these turds, in the upcoming future.  Then of course, there is the more joyful benefit:  the fact that not only Corvette C7 but all other GM turds equipped with the shitty transmission are affected by the failures, sending not just the Stinkray but all other GM turds into a resale value downward spiral.  Obviously, misery loves company.

Finally, with all the mechanical problems, the missing Nurburgring lap time may not matter so much, the ability to keep the latest generation of Corvette in a running condition makes any lap time aspirations so irrelevant.
