Acura has issued a stop-sale order to its dealers and notified the National Highway Traffic Safety Administration of a potential safety defect with new Acura TLX sedans equipped with a V6 engine and nine-speed automatic transmission.
The problem is that transmission components in the TLX might have been damaged during manufacture, according to a technical service bulletin issued by Acura. As a result, the shift indicator could indicate that the transmission is in park when it is not, which could allow the vehicle to roll away.
Nope, ZF did and its the same 9 speed transmission that is in my 2015 Chrysler 200S that has been in the shop for transmission issues for months.

It uses a combination of dog and friction clutches to shift. It relies on the transmission software to make the shifting happen. It is a very complicated design with some major drawbacks in shift quality. I basically had to change my way of driving just for this car.
That's what they get for killing the manual option that the TSX/TL used to have. Seriously, does anyone build a decent automatic tranny?

I'm not sure why people rave about ZF transmissions, the ZF 6 speed in my 335i shifts slower than the one in my 2000 corolla and not nearly as smoothly. Same with other 3 series I've driven.
I have two different ZF 8 speeds and both are great. They shift funny when cold, like most transmissions, but other than that they are very smooth and very fast.
The Corolla tranny probably doesn't have to worry about grenading itself either due to 300ftlbs of torque. The ZF 6 speed feels faster and smoother than the 6L80 in the C6 IMO.
ZFs make them like that, they shift weird when cold to raise temperatures or something. It's not grinding it self at 300ftlbs 99% of the time. Drove my neighbors 328xi and many other 3 series like I said, and they all shift blotchly. I'm pretty sure the V6 camry has more power than a 328 yet shifts better.
Why are we comparing it to GM transmissions
Well I'm going to call it ahead of time and say they'll have a rash of transmission failures. Back when Toyota had the unintended accelerator event covering all the news, I was aware of the problem about 6 months prior to the shit hitting the fan. The problem for me though was that I wasn't sure how to make money off of knowing of the problem prior to everybody else knowing the issue and the whole recall mess so I did nothing.
IIRC, no real problem was ever found, save the one tragedy with the floor mat problem.
The pedal assemblies were recalled out of an abundance of caution because they could possibly return to idle slower than they were supposed to.
