Just a short update for Camaro loves from 2016-2019 with the 8L45E or 8L90 automatic trans. The suit was filed in East Dist. Mich. about all the problems with shifting, heat build up , ect. It will be on the Camaro web site from GM

As much as I HOPE something happens. We know nothing will. GM always finds a way to get out of paying out money for design flaws.

Its crazy that I've had 3 A8s and never had an issue with any of them. I did have the fluid changed in 2 of the 3 for a little shuddering and never had an issue after that. I abused the shit out of my 16 Camaro SS with over 280 passes down the track and 13500 miles and not sure how many miles he has put on it or passes down since he purchased it. The new owner did break the diff on a pass at a Street Car Takeover in 2020. It still has not been flushed and has the original converter in it with original fluid. It is on it 3rd short block which I put in before I sold it. On my second A10 with no issues so far but not sure if they've had problems with them or not.

@laynlo15...yep,it was certainly abused.if that trans didnt break its a miracle...

mine is flawless. in fact i love it. love the pop on the upshifts

Mine's perfect, too. Two precautionary flushes, the last one with the magic 2019 fluid, then a nice stable JRE tune on it, no issues whatsoever before or after.

Paddle response is slower than with the A10, but that's by design, not much one can do about it (although I am still toying with the idea of an inverted paddle switch that activates on release and not at the end of switch travel, which would make it feel faster )

we're all spoilt today i tell you.
back in my day an auto box just had 3 gears and took 2 minutes to change gear lol.
these new autos are amazing.

Not surprised at all about the A8 issues, it is not just GM, several manufacturers have had issues with these 8, 9, 10 speed automatics. More is not always better.

The MT82 was a huge mistake, how ford could allow mass production of mating a transmission rated for a maximum torque that is exceeded by a stock 5.0 coyote is just insanity. A T-56 or TR6060 would have been the correct choices but they decided a fragile grenade prone manual was the right decision. At least they were smart enough to use a T56 in the 03-04 cobras.

What gets me on this is the defense GM uses (bolded below):

Numerous class-action suits have been filed against GM over its 8L45E and 8L90 eight-speed automatic transmissions in recent years. The automaker sought to have one of these suits thrown out last August, claiming the transmission problems are related to a design defect and not a manufacturing defect. GM’s vehicle warranties only cover manufacturing defects with parts and components and not design defects. Most of these suits claim all vehicles with these eight-speed transmissions are defective, which would imply a design defect and not a manufacturing defect.

So - if we make a mistake at the factory and build it incorrectly, we'll fix it. But if we completely screw up the plans in the design center, and then build it to those plans, you are S.O.L., fix it yourself, and you can't sue us. Seems to me they should be MORE liable for design flaws, not less.

GM has always attributed the failures to problems with the fluid, not the mechanicals. So, the question, in my mind, would be, "Did GM knowingly use a fluid they knew was hygroscopic?" I suspect not. So then you look to the fluid manufacturer for their specs on the fluid.
Here's a read way over the heads of any lawyers who ever get involved with this:

Thanks a lot for the article, ctrlz . I can reduce it to this one diagram and a paragraph from the conclusion :

The ingress of water as a contaminant results in short-term friction improvement followed by a steep, consistent degradation over time, ultimately resulting in permanently compromised clutch performance. This appears to corroborate GM's sole focus on resolving the fluid hygroscopy issue.

So the current study indicates possible two mech-
anisms of ATF degradation for water contamination:
(i) rapid reverse micelles formations (responsible for
the sudden increase in friction around 500 cycles in
Figure 3 due to the probable inadequate additive
action) and (ii) promoting aging (responsible for grad-
ually decrease in friction after 1500 cycles). The later
was considered as an impact of water since water eva-
porated during the test, but the degradation still pro-
ceeded and can also be responsible for the previously
observed fast degradation in the friction interfaces,
implies permanent change of the clutch system.

Adding to what was said above...quoted from elsewhere

The new 10 speed that people seem to really like is internally almost identical to the 8 speed with some minor changes, the biggest being changing 1 of the gearsets to feature and additional clutch pack. The fluid flow, housing, asymmetrical pump are largely unchanged.
